The motorcycle  TT Course  is used principally for the  Isle of Man TT  Races and also the separate event of the  Isle of Man Festival of Motorcycling  for the  Manx Grand Prix  and  Classic TT  Races held in September of each year. [ 2 ]  The start-line for the Isle of Man TT Mountain Course is located on Glencrutchery Road in the City of  Douglas, Isle of Man . [ 3 ] The clockwise course has a lap of 37.730 mi (60.721 km), [ 4 ]  from the start line at the  TT Grandstand  on Glencrutchery Road ( A2 Ramsey  to Douglas) in the island's main town of  Douglas . [ 3 ]  After negotiating urban streets, the racing circuit turns right to leave Douglas at  Quarter Bridge , then proceeds along the  A1  Douglas to  Peel  Road from Braddan Bridge, through the villages of  Union Mills ,  Glen Vine ,  Crosby , and  Greeba . The course then turns right at  Ballacraine  on to the  A3 Castletown  to Ramsey road, firstly through countryside glens followed by agricultural land interspersed by the villages of  Kirk Michael ,  Ballaugh  and  Sulby , finally intersecting with the  A18 Snaefell mountain road  after negotiating urban streets in the town of Ramsey. The A18 then takes the course back to Douglas through the highest point, situated after the  Bungalow  at  Hailwood's Height  near the 31st Milestone and the UK Ordnance Survey  spot height  of 1,385 ft (422 m) above sea level. The descent starts through countryside before entering the residential outskirts of Douglas back to the finish line.\n Motor racing began on the Isle of Man in 1904 with the  Gordon Bennett Trial  and originally was restricted to touring automobiles. As the   UK Motor Car Act 1903  placed a speed restriction of 20 mph (32 km\/h) on cars within the United Kingdom, the Secretary of the  Automobile Club of Britain and Ireland  approached the authorities in the Isle of Man to seek permission to race cars on public roads. [ 5 ]  The Highways (Light Locomotives) Act 1904 passed by Tynwald gave permission to use local roads for the 52.15 mi (83.93 km)  Highroads Course  for the 1904 Gordon Bennett Trial. [ 6 ] For the 1905 Gordon Bennett Car event it was decided to run a trial for motor-cycles the day after for a team to represent Great Britain in the International Motor-Cycle Cup Races. The inability of the motorcycle competitors to climb the steep primary  A18  Snaefell Mountain Road section of the course forced the organisers to use a 25-mile (40 km) section of the Gordon Bennett Trial course. For this reason, the  1907 Isle of Man TT  Race used the 15 mi (24 km)  St. John's Short Course . The 1906 Isle of Man Tourist Trophy Race for automobiles the Highroad Course was reduced from 52.15 mi (83.93 km) to 40.38 mi (64.99 km). For the 1908 Tourist Trophy race for automobiles, the course was again reduced to 37.50 mi (60.35 km) with the removal of the Peel and Sandygate loops and was known as the  Four Inch Course . [ 7 ]  The name of the course derives from the regulations for the 1908 Tourist Trophy adopted by the  Royal Automobile Club  which limited the engines of the competing automobiles to a cylinder diameter of 4 inches (100 mm). The Four-Inch Course was adopted by the Auto-Cycle Club for the  1911 races . The Four-Inch Course subsequently became known as the Isle of Man TT Mountain Course or  TT Course  when used for motor-cycle racing. [ 7 ] Course changes: 1920–1939 [ edit ] Brandywell TT Race Marshal Shelter and Weather Station on the A18 Mountain Road\/B10 Sartfield Road looking north towards  Snaefell  Mountain and North Barrule For the  1919 Isle of Man TT , changes were made to the Mountain Course and competitors turned left at  Cronk-ny-Mona  and followed the primary A18 Mountain Road to  Governor's Bridge  with a new start\/finish line on Glencrutchery Road which lengthened the course from the pre- World War I  length of 37.50 mi (60.35 km) to 37.75 mi (60.75 km). An extensive programme of road improvements occurred to many roads in 1922 by the Highway Board including the Mountain Course with road widening at  Sulby Bridge , from Port-e-Chee on the A1 Peel Road to  Braddan Bridge  and part of the main road through Crosby. [ 8 ]  Modification of  Signpost Corner  including rounding off the bend occurred in 1922 along with further road widening at Governor's Bridge with the completion of the link road to A2 Glencrutchery Road\/Governor's Road and the removal of fence posts at  Keppel Gate . [ 9 ]  Further changes to the course followed in 1922 with the adoption of a private road part of the Ballastowle Estate between  Parliament Square  and  May Hill  in Ramsey. [ 10 ]  The course had previously had negotiated the  A2  Albert Road and Tower Road in Ramsey and the new course length was now 37.739 mi (60.735 km). The official course distance for the Snaefell Mountain Course was amended in 1938 to 37.73 mi (60.72 km) which is the current course length. [ 11 ] For the  1934 Isle of Man TT  races major alterations to the TT Mountain Course were carried out which included the removal of the East Snaefell Mountain sheep-gate. [ 12 ]  This was followed by the removal of the hump-backed bridge at  Ballig  and the road work was completed for the Manx Grand Prix in September 1935. Road widening occurred on the Mountain Course at the Highlander,  Laurel Bank ,  Glen Helen  (between the Old Quarry and Brew's Restaurant), and at  Brandywell  with the removal of the Beinn-y-Phott sheep-gate for the  1935 Isle of Man TT  races. [ 13 ]  Road Improvements occurred at the  26th Milestone ,  Greeba Bridge  and on the Sulby Straight for the  1938 Isle of Man TT  races. Further road widening and landscaping occurred at the  Waterworks  with road widening between the  Gooseneck  and the 26th Milestone for the  1939 races . [ 14 ]  A memorial to  Jimmie Guthrie  was built in 1939 at  The Cutting  at a cost of £1,500 [ 15 ]  (equivalent to £117,000 in 2023).\n Course changes: 1947–1999 [ edit ] Route of the  Clypse Course  used 1954–1959 Major road widening occurred on the Mountain course at the 33rd Milestone, including the removal of fence posts at road level and the removal of a section of a grass bank before the start of the  1947 Isle of Man TT  races. [ 16 ]  Changes to the Mountain Course occurred for the  1953 races  including road widening at  Bedstead Corner , elevation works at  Signpost Corner  and  Cronk-ny-Mona , and the widening of the corner at  Gorse Lea . [ 17 ]  Before the commencement of racing for the 1953 Manx Grand Prix, the cottage at  Appledene  Corner was demolished between the 6th and 7th Milestone road-side marker on the primary A1 Douglas to Peel road on the Mountain Course. [ 18 ]  Further changes occurred to the Mountain Course to facilitate racing on the  Clypse Course  and during the winter of 1953\/54 road widening occurred on the primary A18 Mountain Road at  Creg-ny-Baa , Signpost Corner,  Cronk-ny-Mona , and at the approach to  Governor's Bridge . [ 19 ]  The approach to the  Quarterbridge  on the primary A2 Douglas to Peel road was widened and re-profiled and the jumps at the  Highlander  and adjacent to  Ballagarraghyn  Cottages were removed for the  1954 Isle of Man TT  Races. [ 20 ]  Other major course alterations for the 1954 Isle of Man TT Races included road widening at Appledene,  Handley's Corner , Barregarrow,  Rhencullen ,  Ballaugh Bridge ,  Ginger Hall  ( Sulby ), and  Kerrowmoar . [ 21 ]  During the winter of 1957\/58 the hotel at the  Bungalow  tram-crossing was removed on the Mountain Section of the course. [ 22 ] [ 23 ] During the 1960s further road-widening occurred at Ballig and also at  Greeba Bridge  on the primary A1 Douglas to Peel road. In 1963 a roundabout was added to the road junction at the  Quarterbridge . [ 24 ]  The winter of 1970\/1971 and road-widening occurred on the A18 Mountain Road at  Verandah  by cutting into the hillside. [ 25 ]  During the winter of 1975\/76 road-widening and landscaping by the Isle of Man Highway Board occurred at Snugbrough on the primary A2 road at the 2nd Milestone. [ 26 ]  The winter of 1986 further re-profiling occurred at the Quarterbridge road junction with a new road traffic system including two new mini-roundabouts, the removal of a traffic island, and trees. Road re-profiling and widening occurred at  Quarry Bends  during the winter of 1987. During the winter months of 1991\/1992 the A18 Mountain Road was closed for repair work to the road foundation between the  26th Milestone  and the Mountain Box and also between the  Windy Corner  and  Keppel Gate . [ 27 ] Course changes: 2000–present [ edit ] Governor's Bridge road junction between the A18 Bemahague Road and the A2 Governor's Road From 2003 to 2006, road repair work was carried-out on the primary A3 road from Barregarrow to Cronk-y-Voddy, including  Handley's Corner  and the  11th Milestone . In 2004 the western-side embankment is removed from  Guthrie's Memorial  on the A18 Mountain Road. Also, during the winter of 2004\/2005 road widening occurred at  Windy Corner  followed by  Brandish Corner  during the winter of 2005\/2006 by the Department of Transport. In October 2007 the Department of Transport began road widening at  Braddan Bridge  on the Mountain Course with the creation of a new roundabout incorporating the 'Jubilee Oak' Tree on the A1 Douglas to Peel Road. The Department of Transport also announced the proposal of building a new section of road and roundabout for the Mountain Course with a link road from Signpost Corner to  Governor's Bridge  using the existing A18 Bemahague Road. This road widening scheme began in February 2008 [ 28 ]  with the removal of trees on the Bemahague Estate which included  Government House , the official residence of the  Lieutenant Governor , and the creation of a small mini-roundabout. Further work by the Department of Transport in July and September 2008 included a storm drain and the completion of the mini-roundabout. The TT races and Manx Grand Prix continued to use the original A18 Bemahague Road that runs parallel to the new link road and the  Governor's Dip  for motorcycle racing. In July 2008, the Department of Transport announced a £4 Million road safety scheme for the  Quarterbridge  road junction, including the building of a new roundabout and the demolition of the Quarterbridge Hotel. [ 29 ]  In August 2009, for the  2009 Manx Grand Prix  a section of grass bank is removed from the southern side of  Keppel Gate . This was to provide a run-off area after a practice crash by the Australian TT competitor  Cameron Donald  and a further more serious incident involving Travelling Marshal John McBride at Keppel Gate during the  2009 Isle of Man TT  races.\n Keppel Gate and Keppel Park showing the 2015 landscaping During the winter of 2010, further road construction and repair work was carried out by the Isle of Man Department of Infrastructure Highways Division, and the Isle of Man Water Authority between  Cronk Urleigh  and the 13th Milestone. This was followed by major road resurfacing work between the 13th Milestone and Westwood Corner near Kirk Michael, Barregarrow Hill, and Sulby Straight from Kella Crossroads to  Sulby Bridge  during the spring of 2011. The Highways Division modified the road junction at  Signpost Corner  including improved drainage, elevation changes, and repairs to the road surface in November 2010 [ 30 ]  and the same major repair process of road resurfacing was repeated for the  Quarter Bridge  road junction in February 2011. [ 31 ]  The Department of Infrastructure during the winter of 2011\/2012 removed and re-positioned roadside fence-posts from Brandywell to the 32nd Milestone and from Windy Corner to the 33rd Milestone. During the winter of 2012\/2013 the stone TT Marshal shelter at  Guthrie's Memorial  was demolished. The roadway at  Hillberry Corner  underwent repairs to the carriageway and was resurfaced and re-profiled by the Isle of Man Department of Infrastructure, Highways Division during the spring of 2014. In April 2015, the Highways Division instigated a programme of landscaping at  Keppel Gate  including the removal of a small grass bank on the north-eastern side of the corner, road re-profiling and re-surfacing work. [ 32 ] Official lap records [ edit ] The outright lap record for the TT Mountain Course is 16 minutes and 36.115 seconds at an average of 136.358 mph (219.447 km\/h). This was set by  Peter Hickman  on a  BMW M1000RR  Superstock bike during the 2023 Superstock TT Race Two. [ 33 ] The lap record for the Senior TT race is 16 minutes and 42.778 seconds at an average speed of 135.452 mph (217.989 km\/h) set by Peter Hickman during the 2018 Senior TT Race. The race record is also held by Hickman in 1 hour, 43 minutes and 08,065 seconds; an average race speed of 131.700 mph (211.951 km\/h) achieved during the same 6 lap Senior TT race. [ 34 ] The lap record for the  Sidecar TT  race  is 18 minutes and 42.350 seconds at an average speed of 121.021 mph (194.764 km\/h) set by Ryan Crowe and passenger Callum Crowe during the 2025 Sidecar TT Race 1. [ 35 ]  The race record for the Sidecar TT is 56 minutes and 41.816 seconds, an average race speed of 119.784 mph (192.774 km\/h) for 3 laps (113.00 miles) of the Mountain Course is held by  Ben and Tom Birchall , during the 2023 Sidecar TT Race 2. [ 36 ] In the 2006 TT practice New Zealander  Bruce Anstey  achieved the unofficial current top speed record of 206 mph (332 km\/h) [ 37 ]  at the end of Sulby straight on a Suzuki 1000cc machine. This speed value was registered by the on-board datalogging equipment.\n The same course has also been used for  cycle racing , including  individual time trials  and, from 1936, the  Manx International  massed-start road race. The first race held on 18 June 1936 was won by  Charles Holland  of the Midland Cycle and Athletics Club in 1 hour, 42 minutes and 57 seconds for one lap of the Mountain Course. [ 41 ]  In May 2017 it was announced that the circuit would be used for the 2017  British National Road Race Championships  in June of that year, two weeks after the TT races. [ 42 ] The cycling absolute lap record for the Mountain Course was broken in 2015 by Isle of Man born professional cyclist  Peter Kennaugh  in a time of 1 hour, 23 minutes and 48 seconds, [ 43 ]  beating the previous longstanding record, set by former Olympic cyclist  Chris Boardman  in 1993, by 6 seconds. [ 44 ] On 6 June 1990  Tony Pond  completed the first 100 mph (160 km\/h) average-speed lap in 22 minutes, 9.1 seconds driving a  Rover 827 Vitesse . [ 45 ] In 2011  Mark Higgins  completed a lap in 19 minutes, 56.67 seconds at an average speed over 113 mph (182 km\/h) driving a USAC Rally America specification  Prodrive  prepared 4-door  Subaru WRX STI .\n In 2014 Mark Higgins broke his own record driving a 2015 model  Subaru WRX STI  with a lap time of 19 minutes, 15.88 at an average speed of 117.510 mph (189.114 km\/h). [ 46 ] On 4 June 2016 Higgins improved on his record with a lap in 17 minutes 49.75 seconds, an average speed of 126.971 mph (204.340 km\/h) driving a 2016 model of the same car. [ 47 ]  Then a few days later he went even quicker completing the lap in 17 minutes 35 seconds, an average speed of 128.73 mph (207.17 km\/h). [ 48 ] This section is about corners named after Isle of Man TT riders. TT Race Marshal Signal Box on the A18 Mountain Road looking north towards  Guthrie's Memorial  and the Point of Ayre There are 219 corners on the Mountain Course with about 60 named corners, some named after individuals. The first corner to be named after a competitor was Edges Corner in 1920 on the primary A21  Johnny Watterson's Lane  on the Mountain Course between  Cronk-ny-Mona  and the  A22  Ballanard Road in  Douglas  used for racing between 1911 and 1922. [ 23 ] Part of the TT Course was renamed  Brandish Corner  after Walter Brandish crashed in the right-hand gutter while trying to pass another competitor at Upper Hillberry Corner (previously Telegraph Hill) between  Creg-ny-Baa  and  Hillberry Corner  and broke a leg during practice for the  1923 TT  races. [ 49 ]  During an early morning practice session for the  1927 TT ,  Archie Birkin  swerved in Kirk Michael village to avoid a fish-van travelling to Peel on the primary A3 road, collided with a wall and was killed. The corner was then named  Birkin's Bend , and afterwards, from 1928, practice sessions for the TT races and  Manx Grand Prix  were held on closed roads. The Ballameanagh Corner between the  11th Milestone  and the 12th Milestone was renamed  Handley's Corner  after  Wal Handley , riding a  Rudge  motorcycle, crashed during lap 1 of the  1932 TT Senior race , sustained a back injury and subsequently retired from the race. In 1939 a stone memorial to  Jimmie Guthrie  was built at  The Cutting  on the A18 Snaefell Mountain Road and the S-bend corner was renamed  Guthrie's Memorial . [ 15 ] Following a crash during an evening practice session for the  1950 Isle of Man TT  races by  Bill Doran  between  Ballig  Bridge and  Laurel Bank , the corner was named  Doran's Bend . A stone shelter in a style of a small mountain Alpine Lodge was built in 1955 as a memorial to  Les Graham , the inaugural 500 cc World Champion solo motorcyclist, on the A18 Mountain Road. [ 50 ]  The corner is named  Les Graham Memorial  or sometimes referred to as the  Bungalow Bridge .\n The uphill section of the Mountain Course from the  Bungalow  to the highest point of the course near  Brandywell  was named in 1981 as  Hailwood's Rise , in memory of  Mike Hailwood , the former world motorcycle champion, and the highest point of the course preceding the Brandywell road junction was named  Hailwood's Height . [ 51 ]  In 2003 the 32nd Milestone was named  Duke's , [ 52 ]  after the 1950s world solo motorcycle champion  Geoff Duke , and the  26th Milestone  was named  Joey's  after the former Formula 1 TT motor-cycle champion  Joey Dunlop , who tallied 26 race wins.\n In 2013 the Isle of Man Government took the unusual step of naming corners after active competitors, with 23 times TT winner  John McGuinness , [ 53 ]  and  Dave Molyneux , the most successful Manxman with 17 wins, being honoured. [ 54 ] The latest corners to be named have been named in honour of non-riders who have demonstrated a dedication to the TT. These include Ray Caley, former operator of the shop and post office at the junction of the course with Sulby Glen road who died in 2017. [ 55 ]  Caley's Corner is at the beginning of Sulby Straight. In 2019 Harold Leece was recognised for his garden hospitality to TT spectators with his name on a directional marker board. Harold's corner is the 170 mph right hand bend as the riders approach Gorse Lea. [ 56 ] Between 1911 and 2024 there have been 270 rider competitor fatalities during official practices or races on the Isle of Man TT Mountain Course (this number includes the riders killed during the  Manx Grand Prix , and Clubman TT race series of the late 1940s\/1950s). The first fatality on the TT Course was near  Glen Helen  during practice for the 1911 TT when  Victor Surridge , a works  Rudge-Whitworth  rider, crashed heavily and died of his injuries. [ 57 ]  This was also possibly the first death in the  Isle of Man  of a person in a motorcycle or other road-vehicle accident. [ 58 ] The  A3 Castletown  to  Ramsey  road approaching Douglas Road Corner, Kirk Michael with safety air fencing on the outside of the bend The compulsory use of crash helmets for the  1914 Isle of Man TT  motor-cycle races was the result of a fatal accident to Frank Bateman on the Keppel Gate section of the TT Course near to   Kates Cottage  during the 1913  Senior TT  race. [ 59 ]  The  first introduction of a flag to signify the end of an Isle of Man TT  race was as a result of a fatal accident to  Fred Walker  near to the finish line of the 1914  Junior TT  motor-cycle race after crashing into course boundary boards at St. Ninians Crossroads and Ballaquayle Road in the town of Douglas. [ 60 ] During an early morning practice session for the  1927 Isle of Man TT  races,  Archie Birkin , brother of  Tim Birkin  of the  Bentley Boys  fame, crashed fatally at  Rhencullen  after swerving to avoid a collision with a Fish Van being driven on open roads. [ 61 ]   From 1928 onwards,  practice sessions for the Isle of Man TT Races and  Manx Grand Prix  were held on closed public roads. [ 62 ] During the first lap of the  1934  Lightweight  TT race,  Syd Crabtree, European Grand Prix competitor and winner of the  1929  Lightweight TT, crashed fatally in heavy hill fog on the Mountain section of the TT Course near to the  Stonebreakers Hut on the Verandah section of the course. [ 63 ] [ 64 ]  For the  1935 Isle of Man TT  races,  two motorcycle-equipped Travelling Marshals were employed to search for missing riders, particularly in poor weather conditions on the Mountain section of the TT Course. [ 65 ]  After a fatal crash by  Doug J. Pirie , in poor visibility caused by mountain mist and fog near to the 33rd TT Milestone during the 1935 Lightweight TT, races were delayed or postponed to the next day until the weather improved. [ 66 ]  The first evening practice sessions were introduced for the  1937 Isle of Man TT  races which continue to this day. [ 67 ] Further changes to the Mountain Course occurred during the winter of 1953\/54 as the result of fatalities to competitors during the TT races and Manx Grand Prix from 1951 to 1953. Changes were also made to facilitate the return of  Sidecar TT  on the new  Clypse Course . On safety grounds,  'seeding'  of competitors occurred for the 1959 TT race. The Thursday afternoon practice session from 13:45–17:00 pm introduced in the late 1950s was discontinued for the Centenary  2007 Isle of Man TT  races. Also during the late 1950s, Appledene Cottage was demolished on safety grounds along with  Old Brew's Restaurant  near  Glen Helen  during the early 1960s accompanied by a road widening programme at  Greeba Bridge .\n There were six fatalities among the competitors at the  1970 Isle of Man TT , including world championship contender  Santiago Herrero , making 1970 the deadliest year in the history of the event. [ 68 ] [ 69 ]  Further road safety work during the winter of 1970\/1971 road-widening occurred at the Verandah series of bends and also at the  Bungalow Bridge  by the Isle of Man Highway Board cutting into the hillside. [ 70 ] [ 71 ]  Despite the safety improvements to the Verandah section, while lying in first place on the second lap during the  1972 Isle of Man TT  125 cc  Ultra-Lightweight TT  race held in heavy rain,  Gilberto Parlotti  crashed his 125 cc  Morbidelli  at the Verandah and later died from his injuries. [ 72 ]  From 1973, any weather conditions that would not allow a rescue helicopter to take-off or land would lead to the race start being delayed or postponed at any TT or Manx Grand Prix race. [ 73 ] The A2  Quarterbridge Road  including the road junctions at Selborne Drive and Brunswick Drive and the A2  Bray Hill  were subjected to major road repairs and re-profiling during the winter of 1978\/79 by the Isle of Man Highway Board. This followed a series of fatal accidents during the start of the 1978 Sidecar TT 'A' race, to the Swiss sidecar competitor Ernst Trachsel on Quarterbridge Road, and the sidecar crew of Mac Hobson & Kenny Birch on nearby  Bray Hill . [ 74 ]  For the 1979 TT races the practice of starting competitors in pairs was abandoned followed by the Manx Grand Prix in 2011 after the result of fatal crash at  Alpine Cottage  during the 2010 Junior Manx Grand Prix.\n Competitors at the  TT Grandstand  waiting for the start of the Newcomers Speed Control Lap (denoted by Hi-Visibility orange  tabards ) for the 2010 Manx Grand Prix Following a fatal accident to French newcomer Serge le Moal during the first practice session of the  2004 Isle of Man TT  races, [ 75 ]  a Newcomers Speed Control Lap was introduced for the 2004 Manx Grand Prix followed by the 2005 TT races. A mandatory TT Mountain Course licence for Isle of Man TT and Manx Grand Prix competitors was introduced for 2006. During the winter of 2004\/2005 road widening by the Isle of Man Department of Transport occurred at  Windy Corner  followed by  Brandish Corner  during the winter of 2005\/2006, included a slightly banked section and a constant radius curve as a safety improvement for general road traffic. [ 76 ]  A serious accident occurred at the  26th Milestone  during the  2007 Isle of Man TT  Centenary races on lap 5 of the  Senior race  resulting in the deaths of a competitor and two visiting spectators. [ 77 ] After a series of safety reviews, a number of general  measures were introduced after 2007 for the Isle of Man TT races and the Manx Grand Prix and other events such as the  Southern 100  motor-cycle races and the  Rally Isle of Man .  This included the  introduction of restricted areas, safety fencing and the continued introduction of air-fencing to corners to the Isle of Man TT Mountain Course. Following the start of the 2013 Senior TT race, a competitor lost control on the steep descent of Bray Hill and the racing motor-cycle  collided with a wall and spectators' safety area near the junction of Bray Hill and Cronkbourne Road in the town of Douglas, injuring 11 spectators. [ 78 ] [ 79 ]   During an evening practice session for the  2018 Isle of Man TT ,  a race competitor received serious injuries after colliding with a course inspection car near to  Ballacrye Corner  in Ballaugh parish when travelling in a group of race competitors in the reverse course direction.  The incident occurred  following a red-flag incident near Sky Hill (Churchtown) after a fatal accident to Isle of Man competitor, Dan Kneen. [ 80 ]  Following a meeting of the Strategic Motorsport Group organised by the Isle of Man Government, the Clerk of Course announced procedural changes to red flag incidents.  Competitors would now wait on the course until the incident had been cleared and only travel in   'course direction'   accompanied by TT Travelling Marshals at the front and rear of the convoy.

As the [UK](https:\/\/en.wikipedia.org\/wiki\/UK \"UK\") [Motor Car Act 1903](https:\/\/en.wikipedia.org\/wiki\/Motor_Car_Act_1903 \"Motor Car Act 1903\") placed a speed restriction of 20 mph (32 km\/h) on cars within the United Kingdom, the Secretary of the [Automobile Club of Britain and Ireland](https:\/\/en.wikipedia.org\/wiki\/Royal_Automobile_Club \"Royal Automobile Club\") approached the authorities in the Isle of Man to seek permission to race cars on public roads.[\\[5\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-5) The Highways (Light Locomotives) Act 1904 passed by Tynwald gave permission to use local roads for the 52.15 mi (83.93 km) [Highroads Course](https:\/\/en.wikipedia.org\/wiki\/Highroads_Course \"Highroads Course\") for the 1904 Gordon Bennett Trial.[\\[6\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-6)\n\nFor the 1905 Gordon Bennett Car event it was decided to run a trial for motor-cycles the day after for a team to represent Great Britain in the International Motor-Cycle Cup Races. The inability of the motorcycle competitors to climb the steep primary [A18](https:\/\/en.wikipedia.org\/wiki\/A18_road_\\(Isle_of_Man\\) \"A18 road (Isle of Man)\") Snaefell Mountain Road section of the course forced the organisers to use a 25-mile (40 km) section of the Gordon Bennett Trial course. For this reason, the [1907 Isle of Man TT](https:\/\/en.wikipedia.org\/wiki\/1907_Isle_of_Man_TT \"1907 Isle of Man TT\") Race used the 15 mi (24 km) [St. John's Short Course](https:\/\/en.wikipedia.org\/wiki\/St._John%27s_Short_Course \"St. John's Short Course\"). The 1906 Isle of Man Tourist Trophy Race for automobiles the Highroad Course was reduced from 52.15 mi (83.93 km) to 40.38 mi (64.99 km). For the 1908 Tourist Trophy race for automobiles, the course was again reduced to 37.50 mi (60.35 km) with the removal of the Peel and Sandygate loops and was known as the [Four Inch Course](https:\/\/en.wikipedia.org\/wiki\/Four_Inch_Course \"Four Inch Course\").[\\[7\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-Man'_pp_103-7) The name of the course derives from the regulations for the 1908 Tourist Trophy adopted by the [Royal Automobile Club](https:\/\/en.wikipedia.org\/wiki\/Royal_Automobile_Club \"Royal Automobile Club\") which limited the engines of the competing automobiles to a cylinder diameter of 4 inches (100 mm). The Four-Inch Course was adopted by the Auto-Cycle Club for the [1911 races](https:\/\/en.wikipedia.org\/wiki\/1911_Isle_of_Man_TT \"1911 Isle of Man TT\"). The Four-Inch Course subsequently became known as the Isle of Man TT Mountain Course or *TT Course* when used for motor-cycle racing.[\\[7\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-Man'_pp_103-7)\n\n### Course changes: 1920–1939\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=2 \"Edit section: Course changes: 1920–1939\")\\]\n\n[![](https:\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/7\/7c\/003brandywell.jpg\/250px-003brandywell.jpg)](https:\/\/en.wikipedia.org\/wiki\/File:003brandywell.jpg)\n\nBrandywell TT Race Marshal Shelter and Weather Station on the A18 Mountain Road\/B10 Sartfield Road looking north towards [Snaefell](https:\/\/en.wikipedia.org\/wiki\/Snaefell \"Snaefell\") Mountain and North Barrule\n\nFor the [1919 Isle of Man TT](https:\/\/en.wikipedia.org\/w\/index.php?title=1919_Isle_of_Man_TT&action=edit&redlink=1 \"1919 Isle of Man TT (page does not exist)\"), changes were made to the Mountain Course and competitors turned left at [Cronk-ny-Mona](https:\/\/en.wikipedia.org\/wiki\/Cronk-ny-Mona \"Cronk-ny-Mona\") and followed the primary A18 Mountain Road to [Governor's Bridge](https:\/\/en.wikipedia.org\/wiki\/Governor%27s_Bridge_\\(Isle_of_Man\\) \"Governor's Bridge (Isle of Man)\") with a new start\/finish line on Glencrutchery Road which lengthened the course from the pre-[World War I](https:\/\/en.wikipedia.org\/wiki\/World_War_I \"World War I\") length of 37.50 mi (60.35 km) to 37.75 mi (60.75 km).

This followed a series of fatal accidents during the start of the 1978 Sidecar TT 'A' race, to the Swiss sidecar competitor Ernst Trachsel on Quarterbridge Road, and the sidecar crew of Mac Hobson & Kenny Birch on nearby [Bray Hill](https:\/\/en.wikipedia.org\/wiki\/Bray_Hill \"Bray Hill\").[\\[74\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-74) For the 1979 TT races the practice of starting competitors in pairs was abandoned followed by the Manx Grand Prix in 2011 after the result of fatal crash at [Alpine Cottage](https:\/\/en.wikipedia.org\/wiki\/Alpine_Cottage \"Alpine Cottage\") during the 2010 Junior Manx Grand Prix.\n\n[![](https:\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/d\/d2\/Manx_grand_prix_2010_1823.JPG\/250px-Manx_grand_prix_2010_1823.JPG)](https:\/\/en.wikipedia.org\/wiki\/File:Manx_grand_prix_2010_1823.JPG)\n\nCompetitors at the [TT Grandstand](https:\/\/en.wikipedia.org\/wiki\/TT_Grandstand \"TT Grandstand\") waiting for the start of the Newcomers Speed Control Lap (denoted by Hi-Visibility orange [tabards](https:\/\/en.wikipedia.org\/wiki\/Tabard \"Tabard\")) for the 2010 Manx Grand Prix\n\nFollowing a fatal accident to French newcomer Serge le Moal during the first practice session of the [2004 Isle of Man TT](https:\/\/en.wikipedia.org\/wiki\/2004_Isle_of_Man_TT \"2004 Isle of Man TT\") races,[\\[75\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-75) a Newcomers Speed Control Lap was introduced for the 2004 Manx Grand Prix followed by the 2005 TT races. A mandatory TT Mountain Course licence for Isle of Man TT and Manx Grand Prix competitors was introduced for 2006. During the winter of 2004\/2005 road widening by the Isle of Man Department of Transport occurred at [Windy Corner](https:\/\/en.wikipedia.org\/wiki\/Windy_Corner,_Isle_of_Man \"Windy Corner, Isle of Man\") followed by [Brandish Corner](https:\/\/en.wikipedia.org\/wiki\/Brandish_Corner \"Brandish Corner\") during the winter of 2005\/2006, included a slightly banked section and a constant radius curve as a safety improvement for general road traffic.[\\[76\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-76) A serious accident occurred at the [26th Milestone](https:\/\/en.wikipedia.org\/wiki\/26th_Milestone,_Isle_of_Man \"26th Milestone, Isle of Man\") during the [2007 Isle of Man TT](https:\/\/en.wikipedia.org\/wiki\/2007_Isle_of_Man_TT \"2007 Isle of Man TT\") Centenary races on lap 5 of the [Senior race](https:\/\/en.wikipedia.org\/wiki\/Senior_TT \"Senior TT\") resulting in the deaths of a competitor and two visiting spectators.[\\[77\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-77)\n\nAfter a series of safety reviews, a number of general measures were introduced after 2007 for the Isle of Man TT races and the Manx Grand Prix and other events such as the [Southern 100](https:\/\/en.wikipedia.org\/wiki\/Southern_100 \"Southern 100\") motor-cycle races and the [Rally Isle of Man](https:\/\/en.wikipedia.org\/wiki\/Rally_Isle_of_Man \"Rally Isle of Man\"). This included the introduction of restricted areas, safety fencing and the continued introduction of air-fencing to corners to the Isle of Man TT Mountain Course. Following the start of the 2013 Senior TT race, a competitor lost control on the steep descent of Bray Hill and the racing motor-cycle collided with a wall and spectators' safety area near the junction of Bray Hill and Cronkbourne Road in the town of Douglas, injuring 11 spectators.[\\[78\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-78)[\\[79\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-79) During an evening practice session for the [2018 Isle of Man TT](https:\/\/en.wikipedia.org\/wiki\/2018_Isle_of_Man_TT \"2018 Isle of Man TT\"), a race competitor received serious injuries after colliding with a course inspection car near to [Ballacrye Corner](https:\/\/en.wikipedia.org\/wiki\/Ballacrye_Corner \"Ballacrye Corner\") in Ballaugh parish when travelling in a group of race competitors in the reverse course direction. The incident occurred following a red-flag incident near Sky Hill (Churchtown) after a fatal accident to Isle of Man competitor, Dan Kneen.[\\[80\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-80) Following a meeting of the Strategic Motorsport Group organised by the Isle of Man Government, the Clerk of Course announced procedural changes to red flag incidents. Competitors would now wait on the course until the incident had been cleared and only travel in  *'course direction'*  accompanied by TT Travelling Marshals at the front and rear of the convoy.[\\[81\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-81) After a further legal review by the ACU in 2018 into the cause of the accident and the collision with a course inspection car a number of safety changes were initiated. This included the creation of a new event safety officer and GPS tracking to be fitted to all course inspection cars.[\\[82\\]](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_note-82)\n\n## See also\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=11 \"Edit section: See also\")\\]\n\n- [List of Isle of Man TT Mountain Course fatalities](https:\/\/en.wikipedia.org\/wiki\/List_of_Isle_of_Man_TT_Mountain_Course_fatalities \"List of Isle of Man TT Mountain Course fatalities\")\n- [Isle of Man TT Races](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Races \"Isle of Man TT Races\")\n- [Manx Grand Prix](https:\/\/en.wikipedia.org\/wiki\/Manx_Grand_Prix \"Manx Grand Prix\")\n- [Clypse Course](https:\/\/en.wikipedia.org\/wiki\/Clypse_Course \"Clypse Course\")\n- [St. John's Short Course](https:\/\/en.wikipedia.org\/wiki\/St._John%27s_Short_Course \"St. John's Short Course\")\n\n## Sources\n\\[[edit](https:\/\/en.wikipedia.org\/w\/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=12 \"Edit section: Sources\")\\]\n\n1. **[^](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_ref-1)** *Isle of Man Centenary TT – ACU\/MMCC Official Race Guide* page 67 Isle of Man Department of Tourism and Leisure (2007) Mannin Media Group Ltd\n2. **[^](https:\/\/en.wikipedia.org\/wiki\/Isle_of_Man_TT_Mountain_Course#cite_ref-2)** International Isle of Man Tourist Trophy – 2018 Regulations page 26 Section 7 Qualifying and Race Procedure TT Business Development Manager (2018) Isle of Man Department of Economic Development.

Boilerpipe Text	Motorcycle circuit on the Isle of Man The Isle of Man TT Mountain Course or TT Course or Snaefell Mountain Course or Elmo’s Mountain Course [ 1 ] is a street and public rural road circuit located in the Isle of Man , used for motorcycle racing. The motorcycle TT Course is used principally for the Isle of Man TT Races and also the separate event of the Isle of Man Festival of Motorcycling for the Manx Grand Prix and Classic TT Races held in September of each year. [ 2 ] The start-line for the Isle of Man TT Mountain Course is located on Glencrutchery Road in the City of Douglas, Isle of Man . [ 3 ] The clockwise course has a lap of 37.730 mi (60.721 km), [ 4 ] from the start line at the TT Grandstand on Glencrutchery Road ( A2 Ramsey to Douglas) in the island's main town of Douglas . [ 3 ] After negotiating urban streets, the racing circuit turns right to leave Douglas at Quarter Bridge , then proceeds along the A1 Douglas to Peel Road from Braddan Bridge, through the villages of Union Mills , Glen Vine , Crosby , and Greeba . The course then turns right at Ballacraine on to the A3 Castletown to Ramsey road, firstly through countryside glens followed by agricultural land interspersed by the villages of Kirk Michael , Ballaugh and Sulby , finally intersecting with the A18 Snaefell mountain road after negotiating urban streets in the town of Ramsey. The A18 then takes the course back to Douglas through the highest point, situated after the Bungalow at Hailwood's Height near the 31st Milestone and the UK Ordnance Survey spot height of 1,385 ft (422 m) above sea level. The descent starts through countryside before entering the residential outskirts of Douglas back to the finish line. Motor racing began on the Isle of Man in 1904 with the Gordon Bennett Trial and originally was restricted to touring automobiles. As the UK Motor Car Act 1903 placed a speed restriction of 20 mph (32 km/h) on cars within the United Kingdom, the Secretary of the Automobile Club of Britain and Ireland approached the authorities in the Isle of Man to seek permission to race cars on public roads. [ 5 ] The Highways (Light Locomotives) Act 1904 passed by Tynwald gave permission to use local roads for the 52.15 mi (83.93 km) Highroads Course for the 1904 Gordon Bennett Trial. [ 6 ] For the 1905 Gordon Bennett Car event it was decided to run a trial for motor-cycles the day after for a team to represent Great Britain in the International Motor-Cycle Cup Races. The inability of the motorcycle competitors to climb the steep primary A18 Snaefell Mountain Road section of the course forced the organisers to use a 25-mile (40 km) section of the Gordon Bennett Trial course. For this reason, the 1907 Isle of Man TT Race used the 15 mi (24 km) St. John's Short Course . The 1906 Isle of Man Tourist Trophy Race for automobiles the Highroad Course was reduced from 52.15 mi (83.93 km) to 40.38 mi (64.99 km). For the 1908 Tourist Trophy race for automobiles, the course was again reduced to 37.50 mi (60.35 km) with the removal of the Peel and Sandygate loops and was known as the Four Inch Course . [ 7 ] The name of the course derives from the regulations for the 1908 Tourist Trophy adopted by the Royal Automobile Club which limited the engines of the competing automobiles to a cylinder diameter of 4 inches (100 mm). The Four-Inch Course was adopted by the Auto-Cycle Club for the 1911 races . The Four-Inch Course subsequently became known as the Isle of Man TT Mountain Course or TT Course when used for motor-cycle racing. [ 7 ] Course changes: 1920–1939 [ edit ] Brandywell TT Race Marshal Shelter and Weather Station on the A18 Mountain Road/B10 Sartfield Road looking north towards Snaefell Mountain and North Barrule For the 1919 Isle of Man TT , changes were made to the Mountain Course and competitors turned left at Cronk-ny-Mona and followed the primary A18 Mountain Road to Governor's Bridge with a new start/finish line on Glencrutchery Road which lengthened the course from the pre- World War I length of 37.50 mi (60.35 km) to 37.75 mi (60.75 km). An extensive programme of road improvements occurred to many roads in 1922 by the Highway Board including the Mountain Course with road widening at Sulby Bridge , from Port-e-Chee on the A1 Peel Road to Braddan Bridge and part of the main road through Crosby. [ 8 ] Modification of Signpost Corner including rounding off the bend occurred in 1922 along with further road widening at Governor's Bridge with the completion of the link road to A2 Glencrutchery Road/Governor's Road and the removal of fence posts at Keppel Gate . [ 9 ] Further changes to the course followed in 1922 with the adoption of a private road part of the Ballastowle Estate between Parliament Square and May Hill in Ramsey. [ 10 ] The course had previously had negotiated the A2 Albert Road and Tower Road in Ramsey and the new course length was now 37.739 mi (60.735 km). The official course distance for the Snaefell Mountain Course was amended in 1938 to 37.73 mi (60.72 km) which is the current course length. [ 11 ] For the 1934 Isle of Man TT races major alterations to the TT Mountain Course were carried out which included the removal of the East Snaefell Mountain sheep-gate. [ 12 ] This was followed by the removal of the hump-backed bridge at Ballig and the road work was completed for the Manx Grand Prix in September 1935. Road widening occurred on the Mountain Course at the Highlander, Laurel Bank , Glen Helen (between the Old Quarry and Brew's Restaurant), and at Brandywell with the removal of the Beinn-y-Phott sheep-gate for the 1935 Isle of Man TT races. [ 13 ] Road Improvements occurred at the 26th Milestone , Greeba Bridge and on the Sulby Straight for the 1938 Isle of Man TT races. Further road widening and landscaping occurred at the Waterworks with road widening between the Gooseneck and the 26th Milestone for the 1939 races . [ 14 ] A memorial to Jimmie Guthrie was built in 1939 at The Cutting at a cost of £1,500 [ 15 ] (equivalent to £117,000 in 2023). Course changes: 1947–1999 [ edit ] Route of the Clypse Course used 1954–1959 Major road widening occurred on the Mountain course at the 33rd Milestone, including the removal of fence posts at road level and the removal of a section of a grass bank before the start of the 1947 Isle of Man TT races. [ 16 ] Changes to the Mountain Course occurred for the 1953 races including road widening at Bedstead Corner , elevation works at Signpost Corner and Cronk-ny-Mona , and the widening of the corner at Gorse Lea . [ 17 ] Before the commencement of racing for the 1953 Manx Grand Prix, the cottage at Appledene Corner was demolished between the 6th and 7th Milestone road-side marker on the primary A1 Douglas to Peel road on the Mountain Course. [ 18 ] Further changes occurred to the Mountain Course to facilitate racing on the Clypse Course and during the winter of 1953/54 road widening occurred on the primary A18 Mountain Road at Creg-ny-Baa , Signpost Corner, Cronk-ny-Mona , and at the approach to Governor's Bridge . [ 19 ] The approach to the Quarterbridge on the primary A2 Douglas to Peel road was widened and re-profiled and the jumps at the Highlander and adjacent to Ballagarraghyn Cottages were removed for the 1954 Isle of Man TT Races. [ 20 ] Other major course alterations for the 1954 Isle of Man TT Races included road widening at Appledene, Handley's Corner , Barregarrow, Rhencullen , Ballaugh Bridge , Ginger Hall ( Sulby ), and Kerrowmoar . [ 21 ] During the winter of 1957/58 the hotel at the Bungalow tram-crossing was removed on the Mountain Section of the course. [ 22 ] [ 23 ] During the 1960s further road-widening occurred at Ballig and also at Greeba Bridge on the primary A1 Douglas to Peel road. In 1963 a roundabout was added to the road junction at the Quarterbridge . [ 24 ] The winter of 1970/1971 and road-widening occurred on the A18 Mountain Road at Verandah by cutting into the hillside. [ 25 ] During the winter of 1975/76 road-widening and landscaping by the Isle of Man Highway Board occurred at Snugbrough on the primary A2 road at the 2nd Milestone. [ 26 ] The winter of 1986 further re-profiling occurred at the Quarterbridge road junction with a new road traffic system including two new mini-roundabouts, the removal of a traffic island, and trees. Road re-profiling and widening occurred at Quarry Bends during the winter of 1987. During the winter months of 1991/1992 the A18 Mountain Road was closed for repair work to the road foundation between the 26th Milestone and the Mountain Box and also between the Windy Corner and Keppel Gate . [ 27 ] Course changes: 2000–present [ edit ] Governor's Bridge road junction between the A18 Bemahague Road and the A2 Governor's Road From 2003 to 2006, road repair work was carried-out on the primary A3 road from Barregarrow to Cronk-y-Voddy, including Handley's Corner and the 11th Milestone . In 2004 the western-side embankment is removed from Guthrie's Memorial on the A18 Mountain Road. Also, during the winter of 2004/2005 road widening occurred at Windy Corner followed by Brandish Corner during the winter of 2005/2006 by the Department of Transport. In October 2007 the Department of Transport began road widening at Braddan Bridge on the Mountain Course with the creation of a new roundabout incorporating the 'Jubilee Oak' Tree on the A1 Douglas to Peel Road. The Department of Transport also announced the proposal of building a new section of road and roundabout for the Mountain Course with a link road from Signpost Corner to Governor's Bridge using the existing A18 Bemahague Road. This road widening scheme began in February 2008 [ 28 ] with the removal of trees on the Bemahague Estate which included Government House , the official residence of the Lieutenant Governor , and the creation of a small mini-roundabout. Further work by the Department of Transport in July and September 2008 included a storm drain and the completion of the mini-roundabout. The TT races and Manx Grand Prix continued to use the original A18 Bemahague Road that runs parallel to the new link road and the Governor's Dip for motorcycle racing. In July 2008, the Department of Transport announced a £4 Million road safety scheme for the Quarterbridge road junction, including the building of a new roundabout and the demolition of the Quarterbridge Hotel. [ 29 ] In August 2009, for the 2009 Manx Grand Prix a section of grass bank is removed from the southern side of Keppel Gate . This was to provide a run-off area after a practice crash by the Australian TT competitor Cameron Donald and a further more serious incident involving Travelling Marshal John McBride at Keppel Gate during the 2009 Isle of Man TT races. Keppel Gate and Keppel Park showing the 2015 landscaping During the winter of 2010, further road construction and repair work was carried out by the Isle of Man Department of Infrastructure Highways Division, and the Isle of Man Water Authority between Cronk Urleigh and the 13th Milestone. This was followed by major road resurfacing work between the 13th Milestone and Westwood Corner near Kirk Michael, Barregarrow Hill, and Sulby Straight from Kella Crossroads to Sulby Bridge during the spring of 2011. The Highways Division modified the road junction at Signpost Corner including improved drainage, elevation changes, and repairs to the road surface in November 2010 [ 30 ] and the same major repair process of road resurfacing was repeated for the Quarter Bridge road junction in February 2011. [ 31 ] The Department of Infrastructure during the winter of 2011/2012 removed and re-positioned roadside fence-posts from Brandywell to the 32nd Milestone and from Windy Corner to the 33rd Milestone. During the winter of 2012/2013 the stone TT Marshal shelter at Guthrie's Memorial was demolished. The roadway at Hillberry Corner underwent repairs to the carriageway and was resurfaced and re-profiled by the Isle of Man Department of Infrastructure, Highways Division during the spring of 2014. In April 2015, the Highways Division instigated a programme of landscaping at Keppel Gate including the removal of a small grass bank on the north-eastern side of the corner, road re-profiling and re-surfacing work. [ 32 ] Official lap records [ edit ] The outright lap record for the TT Mountain Course is 16 minutes and 36.115 seconds at an average of 136.358 mph (219.447 km/h). This was set by Peter Hickman on a BMW M1000RR Superstock bike during the 2023 Superstock TT Race Two. [ 33 ] The lap record for the Senior TT race is 16 minutes and 42.778 seconds at an average speed of 135.452 mph (217.989 km/h) set by Peter Hickman during the 2018 Senior TT Race. The race record is also held by Hickman in 1 hour, 43 minutes and 08,065 seconds; an average race speed of 131.700 mph (211.951 km/h) achieved during the same 6 lap Senior TT race. [ 34 ] The lap record for the Sidecar TT race is 18 minutes and 42.350 seconds at an average speed of 121.021 mph (194.764 km/h) set by Ryan Crowe and passenger Callum Crowe during the 2025 Sidecar TT Race 1. [ 35 ] The race record for the Sidecar TT is 56 minutes and 41.816 seconds, an average race speed of 119.784 mph (192.774 km/h) for 3 laps (113.00 miles) of the Mountain Course is held by Ben and Tom Birchall , during the 2023 Sidecar TT Race 2. [ 36 ] In the 2006 TT practice New Zealander Bruce Anstey achieved the unofficial current top speed record of 206 mph (332 km/h) [ 37 ] at the end of Sulby straight on a Suzuki 1000cc machine. This speed value was registered by the on-board datalogging equipment. The same course has also been used for cycle racing , including individual time trials and, from 1936, the Manx International massed-start road race. The first race held on 18 June 1936 was won by Charles Holland of the Midland Cycle and Athletics Club in 1 hour, 42 minutes and 57 seconds for one lap of the Mountain Course. [ 41 ] In May 2017 it was announced that the circuit would be used for the 2017 British National Road Race Championships in June of that year, two weeks after the TT races. [ 42 ] The cycling absolute lap record for the Mountain Course was broken in 2015 by Isle of Man born professional cyclist Peter Kennaugh in a time of 1 hour, 23 minutes and 48 seconds, [ 43 ] beating the previous longstanding record, set by former Olympic cyclist Chris Boardman in 1993, by 6 seconds. [ 44 ] On 6 June 1990 Tony Pond completed the first 100 mph (160 km/h) average-speed lap in 22 minutes, 9.1 seconds driving a Rover 827 Vitesse . [ 45 ] In 2011 Mark Higgins completed a lap in 19 minutes, 56.67 seconds at an average speed over 113 mph (182 km/h) driving a USAC Rally America specification Prodrive prepared 4-door Subaru WRX STI . In 2014 Mark Higgins broke his own record driving a 2015 model Subaru WRX STI with a lap time of 19 minutes, 15.88 at an average speed of 117.510 mph (189.114 km/h). [ 46 ] On 4 June 2016 Higgins improved on his record with a lap in 17 minutes 49.75 seconds, an average speed of 126.971 mph (204.340 km/h) driving a 2016 model of the same car. [ 47 ] Then a few days later he went even quicker completing the lap in 17 minutes 35 seconds, an average speed of 128.73 mph (207.17 km/h). [ 48 ] This section is about corners named after Isle of Man TT riders. TT Race Marshal Signal Box on the A18 Mountain Road looking north towards Guthrie's Memorial and the Point of Ayre There are 219 corners on the Mountain Course with about 60 named corners, some named after individuals. The first corner to be named after a competitor was Edges Corner in 1920 on the primary A21 Johnny Watterson's Lane on the Mountain Course between Cronk-ny-Mona and the A22 Ballanard Road in Douglas used for racing between 1911 and 1922. [ 23 ] Part of the TT Course was renamed Brandish Corner after Walter Brandish crashed in the right-hand gutter while trying to pass another competitor at Upper Hillberry Corner (previously Telegraph Hill) between Creg-ny-Baa and Hillberry Corner and broke a leg during practice for the 1923 TT races. [ 49 ] During an early morning practice session for the 1927 TT , Archie Birkin swerved in Kirk Michael village to avoid a fish-van travelling to Peel on the primary A3 road, collided with a wall and was killed. The corner was then named Birkin's Bend , and afterwards, from 1928, practice sessions for the TT races and Manx Grand Prix were held on closed roads. The Ballameanagh Corner between the 11th Milestone and the 12th Milestone was renamed Handley's Corner after Wal Handley , riding a Rudge motorcycle, crashed during lap 1 of the 1932 TT Senior race , sustained a back injury and subsequently retired from the race. In 1939 a stone memorial to Jimmie Guthrie was built at The Cutting on the A18 Snaefell Mountain Road and the S-bend corner was renamed Guthrie's Memorial . [ 15 ] Following a crash during an evening practice session for the 1950 Isle of Man TT races by Bill Doran between Ballig Bridge and Laurel Bank , the corner was named Doran's Bend . A stone shelter in a style of a small mountain Alpine Lodge was built in 1955 as a memorial to Les Graham , the inaugural 500 cc World Champion solo motorcyclist, on the A18 Mountain Road. [ 50 ] The corner is named Les Graham Memorial or sometimes referred to as the Bungalow Bridge . The uphill section of the Mountain Course from the Bungalow to the highest point of the course near Brandywell was named in 1981 as Hailwood's Rise , in memory of Mike Hailwood , the former world motorcycle champion, and the highest point of the course preceding the Brandywell road junction was named Hailwood's Height . [ 51 ] In 2003 the 32nd Milestone was named Duke's , [ 52 ] after the 1950s world solo motorcycle champion Geoff Duke , and the 26th Milestone was named Joey's after the former Formula 1 TT motor-cycle champion Joey Dunlop , who tallied 26 race wins. In 2013 the Isle of Man Government took the unusual step of naming corners after active competitors, with 23 times TT winner John McGuinness , [ 53 ] and Dave Molyneux , the most successful Manxman with 17 wins, being honoured. [ 54 ] The latest corners to be named have been named in honour of non-riders who have demonstrated a dedication to the TT. These include Ray Caley, former operator of the shop and post office at the junction of the course with Sulby Glen road who died in 2017. [ 55 ] Caley's Corner is at the beginning of Sulby Straight. In 2019 Harold Leece was recognised for his garden hospitality to TT spectators with his name on a directional marker board. Harold's corner is the 170 mph right hand bend as the riders approach Gorse Lea. [ 56 ] Between 1911 and 2024 there have been 270 rider competitor fatalities during official practices or races on the Isle of Man TT Mountain Course (this number includes the riders killed during the Manx Grand Prix , and Clubman TT race series of the late 1940s/1950s). The first fatality on the TT Course was near Glen Helen during practice for the 1911 TT when Victor Surridge , a works Rudge-Whitworth rider, crashed heavily and died of his injuries. [ 57 ] This was also possibly the first death in the Isle of Man of a person in a motorcycle or other road-vehicle accident. [ 58 ] The A3 Castletown to Ramsey road approaching Douglas Road Corner, Kirk Michael with safety air fencing on the outside of the bend The compulsory use of crash helmets for the 1914 Isle of Man TT motor-cycle races was the result of a fatal accident to Frank Bateman on the Keppel Gate section of the TT Course near to Kates Cottage during the 1913 Senior TT race. [ 59 ] The first introduction of a flag to signify the end of an Isle of Man TT race was as a result of a fatal accident to Fred Walker near to the finish line of the 1914 Junior TT motor-cycle race after crashing into course boundary boards at St. Ninians Crossroads and Ballaquayle Road in the town of Douglas. [ 60 ] During an early morning practice session for the 1927 Isle of Man TT races, Archie Birkin , brother of Tim Birkin of the Bentley Boys fame, crashed fatally at Rhencullen after swerving to avoid a collision with a Fish Van being driven on open roads. [ 61 ] From 1928 onwards, practice sessions for the Isle of Man TT Races and Manx Grand Prix were held on closed public roads. [ 62 ] During the first lap of the 1934 Lightweight TT race, Syd Crabtree, European Grand Prix competitor and winner of the 1929 Lightweight TT, crashed fatally in heavy hill fog on the Mountain section of the TT Course near to the Stonebreakers Hut on the Verandah section of the course. [ 63 ] [ 64 ] For the 1935 Isle of Man TT races, two motorcycle-equipped Travelling Marshals were employed to search for missing riders, particularly in poor weather conditions on the Mountain section of the TT Course. [ 65 ] After a fatal crash by Doug J. Pirie , in poor visibility caused by mountain mist and fog near to the 33rd TT Milestone during the 1935 Lightweight TT, races were delayed or postponed to the next day until the weather improved. [ 66 ] The first evening practice sessions were introduced for the 1937 Isle of Man TT races which continue to this day. [ 67 ] Further changes to the Mountain Course occurred during the winter of 1953/54 as the result of fatalities to competitors during the TT races and Manx Grand Prix from 1951 to 1953. Changes were also made to facilitate the return of Sidecar TT on the new Clypse Course . On safety grounds, 'seeding' of competitors occurred for the 1959 TT race. The Thursday afternoon practice session from 13:45–17:00 pm introduced in the late 1950s was discontinued for the Centenary 2007 Isle of Man TT races. Also during the late 1950s, Appledene Cottage was demolished on safety grounds along with Old Brew's Restaurant near Glen Helen during the early 1960s accompanied by a road widening programme at Greeba Bridge . There were six fatalities among the competitors at the 1970 Isle of Man TT , including world championship contender Santiago Herrero , making 1970 the deadliest year in the history of the event. [ 68 ] [ 69 ] Further road safety work during the winter of 1970/1971 road-widening occurred at the Verandah series of bends and also at the Bungalow Bridge by the Isle of Man Highway Board cutting into the hillside. [ 70 ] [ 71 ] Despite the safety improvements to the Verandah section, while lying in first place on the second lap during the 1972 Isle of Man TT 125 cc Ultra-Lightweight TT race held in heavy rain, Gilberto Parlotti crashed his 125 cc Morbidelli at the Verandah and later died from his injuries. [ 72 ] From 1973, any weather conditions that would not allow a rescue helicopter to take-off or land would lead to the race start being delayed or postponed at any TT or Manx Grand Prix race. [ 73 ] The A2 Quarterbridge Road including the road junctions at Selborne Drive and Brunswick Drive and the A2 Bray Hill were subjected to major road repairs and re-profiling during the winter of 1978/79 by the Isle of Man Highway Board. This followed a series of fatal accidents during the start of the 1978 Sidecar TT 'A' race, to the Swiss sidecar competitor Ernst Trachsel on Quarterbridge Road, and the sidecar crew of Mac Hobson & Kenny Birch on nearby Bray Hill . [ 74 ] For the 1979 TT races the practice of starting competitors in pairs was abandoned followed by the Manx Grand Prix in 2011 after the result of fatal crash at Alpine Cottage during the 2010 Junior Manx Grand Prix. Competitors at the TT Grandstand waiting for the start of the Newcomers Speed Control Lap (denoted by Hi-Visibility orange tabards ) for the 2010 Manx Grand Prix Following a fatal accident to French newcomer Serge le Moal during the first practice session of the 2004 Isle of Man TT races, [ 75 ] a Newcomers Speed Control Lap was introduced for the 2004 Manx Grand Prix followed by the 2005 TT races. A mandatory TT Mountain Course licence for Isle of Man TT and Manx Grand Prix competitors was introduced for 2006. During the winter of 2004/2005 road widening by the Isle of Man Department of Transport occurred at Windy Corner followed by Brandish Corner during the winter of 2005/2006, included a slightly banked section and a constant radius curve as a safety improvement for general road traffic. [ 76 ] A serious accident occurred at the 26th Milestone during the 2007 Isle of Man TT Centenary races on lap 5 of the Senior race resulting in the deaths of a competitor and two visiting spectators. [ 77 ] After a series of safety reviews, a number of general measures were introduced after 2007 for the Isle of Man TT races and the Manx Grand Prix and other events such as the Southern 100 motor-cycle races and the Rally Isle of Man . This included the introduction of restricted areas, safety fencing and the continued introduction of air-fencing to corners to the Isle of Man TT Mountain Course. Following the start of the 2013 Senior TT race, a competitor lost control on the steep descent of Bray Hill and the racing motor-cycle collided with a wall and spectators' safety area near the junction of Bray Hill and Cronkbourne Road in the town of Douglas, injuring 11 spectators. [ 78 ] [ 79 ] During an evening practice session for the 2018 Isle of Man TT , a race competitor received serious injuries after colliding with a course inspection car near to Ballacrye Corner in Ballaugh parish when travelling in a group of race competitors in the reverse course direction. The incident occurred following a red-flag incident near Sky Hill (Churchtown) after a fatal accident to Isle of Man competitor, Dan Kneen. [ 80 ] Following a meeting of the Strategic Motorsport Group organised by the Isle of Man Government, the Clerk of Course announced procedural changes to red flag incidents. Competitors would now wait on the course until the incident had been cleared and only travel in 'course direction' accompanied by TT Travelling Marshals at the front and rear of the convoy. [ 81 ] After a further legal review by the ACU in 2018 into the cause of the accident and the collision with a course inspection car a number of safety changes were initiated. This included the creation of a new event safety officer and GPS tracking to be fitted to all course inspection cars.

The descent starts through countryside before entering the residential outskirts of Douglas back to the finish line. ## History \[[edit](https://en.wikipedia.org/w/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=1 "Edit section: History")\] Motor racing began on the Isle of Man in 1904 with the [Gordon Bennett Trial](https://en.wikipedia.org/wiki/Gordon_Bennett_Cup_\(auto_racing\) "Gordon Bennett Cup (auto racing)") and originally was restricted to touring automobiles. As the [UK](https://en.wikipedia.org/wiki/UK "UK") [Motor Car Act 1903](https://en.wikipedia.org/wiki/Motor_Car_Act_1903 "Motor Car Act 1903") placed a speed restriction of 20 mph (32 km/h) on cars within the United Kingdom, the Secretary of the [Automobile Club of Britain and Ireland](https://en.wikipedia.org/wiki/Royal_Automobile_Club "Royal Automobile Club") approached the authorities in the Isle of Man to seek permission to race cars on public roads.[\[5\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-5) The Highways (Light Locomotives) Act 1904 passed by Tynwald gave permission to use local roads for the 52.15 mi (83.93 km) [Highroads Course](https://en.wikipedia.org/wiki/Highroads_Course "Highroads Course") for the 1904 Gordon Bennett Trial.[\[6\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-6) For the 1905 Gordon Bennett Car event it was decided to run a trial for motor-cycles the day after for a team to represent Great Britain in the International Motor-Cycle Cup Races. The inability of the motorcycle competitors to climb the steep primary [A18](https://en.wikipedia.org/wiki/A18_road_\(Isle_of_Man\) "A18 road (Isle of Man)") Snaefell Mountain Road section of the course forced the organisers to use a 25-mile (40 km) section of the Gordon Bennett Trial course. For this reason, the [1907 Isle of Man TT](https://en.wikipedia.org/wiki/1907_Isle_of_Man_TT "1907 Isle of Man TT") Race used the 15 mi (24 km) [St. John's Short Course](https://en.wikipedia.org/wiki/St._John%27s_Short_Course "St. John's Short Course"). The 1906 Isle of Man Tourist Trophy Race for automobiles the Highroad Course was reduced from 52.15 mi (83.93 km) to 40.38 mi (64.99 km). For the 1908 Tourist Trophy race for automobiles, the course was again reduced to 37.50 mi (60.35 km) with the removal of the Peel and Sandygate loops and was known as the [Four Inch Course](https://en.wikipedia.org/wiki/Four_Inch_Course "Four Inch Course").[\[7\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-Man'_pp_103-7) The name of the course derives from the regulations for the 1908 Tourist Trophy adopted by the [Royal Automobile Club](https://en.wikipedia.org/wiki/Royal_Automobile_Club "Royal Automobile Club") which limited the engines of the competing automobiles to a cylinder diameter of 4 inches (100 mm). The Four-Inch Course was adopted by the Auto-Cycle Club for the [1911 races](https://en.wikipedia.org/wiki/1911_Isle_of_Man_TT "1911 Isle of Man TT"). The Four-Inch Course subsequently became known as the Isle of Man TT Mountain Course or TT Course when used for motor-cycle racing.[\[7\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-Man'_pp_103-7) ### Course changes: 1920–1939 \[[edit](https://en.wikipedia.org/w/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=2 "Edit section: Course changes: 1920–1939")\] [![](https://upload.wikimedia.org/wikipedia/commons/thumb/7/7c/003brandywell.jpg/250px-003brandywell.jpg)](https://en.wikipedia.org/wiki/File:003brandywell.jpg) Brandywell TT Race Marshal Shelter and Weather Station on the A18 Mountain Road/B10 Sartfield Road looking north towards [Snaefell](https://en.wikipedia.org/wiki/Snaefell "Snaefell") Mountain and North Barrule For the [1919 Isle of Man TT](https://en.wikipedia.org/w/index.php?title=1919_Isle_of_Man_TT&action=edit&redlink=1 "1919 Isle of Man TT (page does not exist)"), changes were made to the Mountain Course and competitors turned left at [Cronk-ny-Mona](https://en.wikipedia.org/wiki/Cronk-ny-Mona "Cronk-ny-Mona") and followed the primary A18 Mountain Road to [Governor's Bridge](https://en.wikipedia.org/wiki/Governor%27s_Bridge_\(Isle_of_Man\) "Governor's Bridge (Isle of Man)") with a new start/finish line on Glencrutchery Road which lengthened the course from the pre-[World War I](https://en.wikipedia.org/wiki/World_War_I "World War I") length of 37.50 mi (60.35 km) to 37.75 mi (60.75 km). An extensive programme of road improvements occurred to many roads in 1922 by the Highway Board including the Mountain Course with road widening at [Sulby Bridge](https://en.wikipedia.org/wiki/Sulby_Bridge "Sulby Bridge"), from Port-e-Chee on the A1 Peel Road to [Braddan Bridge](https://en.wikipedia.org/wiki/Braddan_Bridge "Braddan Bridge") and part of the main road through Crosby.[\[8\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-8) Modification of [Signpost Corner](https://en.wikipedia.org/wiki/Signpost_Corner "Signpost Corner") including rounding off the bend occurred in 1922 along with further road widening at Governor's Bridge with the completion of the link road to A2 Glencrutchery Road/Governor's Road and the removal of fence posts at [Keppel Gate](https://en.wikipedia.org/wiki/Keppel_Gate "Keppel Gate").[\[9\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-9) Further changes to the course followed in 1922 with the adoption of a private road part of the Ballastowle Estate between [Parliament Square](https://en.wikipedia.org/wiki/Parliament_Square,_Ramsey "Parliament Square, Ramsey") and [May Hill](https://en.wikipedia.org/wiki/May_Hill,_Gloucestershire "May Hill, Gloucestershire") in Ramsey.[\[10\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-10) The course had previously had negotiated the [A2](https://en.wikipedia.org/wiki/A2_road_\(Isle_of_Man\) "A2 road (Isle of Man)") Albert Road and Tower Road in Ramsey and the new course length was now 37.739 mi (60.735 km). The official course distance for the Snaefell Mountain Course was amended in 1938 to 37.73 mi (60.72 km) which is the current course length.[\[11\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-11) For the [1934 Isle of Man TT](https://en.wikipedia.org/wiki/1934_Isle_of_Man_TT "1934 Isle of Man TT") races major alterations to the TT Mountain Course were carried out which included the removal of the East Snaefell Mountain sheep-gate.[\[12\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-12) This was followed by the removal of the hump-backed bridge at [Ballig](https://en.wikipedia.org/wiki/Ballig "Ballig") and the road work was completed for the Manx Grand Prix in September 1935.

In 1939 a stone memorial to [Jimmie Guthrie](https://en.wikipedia.org/wiki/Jimmie_Guthrie "Jimmie Guthrie") was built at The Cutting on the A18 Snaefell Mountain Road and the S-bend corner was renamed [Guthrie's Memorial](https://en.wikipedia.org/wiki/Guthrie%27s_Memorial "Guthrie's Memorial").[\[15\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-Man_Weekly_Times'_pp18-15) Following a crash during an evening practice session for the [1950 Isle of Man TT](https://en.wikipedia.org/wiki/1950_Isle_of_Man_TT "1950 Isle of Man TT") races by [Bill Doran](https://en.wikipedia.org/wiki/Bill_Doran_\(motorcyclist\) "Bill Doran (motorcyclist)") between [Ballig](https://en.wikipedia.org/wiki/Ballig "Ballig") Bridge and [Laurel Bank](https://en.wikipedia.org/wiki/Laurel_Bank "Laurel Bank"), the corner was named [Doran's Bend](https://en.wikipedia.org/wiki/Doran%27s_Bend "Doran's Bend"). A stone shelter in a style of a small mountain Alpine Lodge was built in 1955 as a memorial to [Les Graham](https://en.wikipedia.org/wiki/Leslie_Graham "Leslie Graham"), the inaugural 500 cc World Champion solo motorcyclist, on the A18 Mountain Road.[\[50\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-50) The corner is named [Les Graham Memorial](https://en.wikipedia.org/wiki/Bungalow_Bridge "Bungalow Bridge") or sometimes referred to as the Bungalow Bridge. The uphill section of the Mountain Course from the [Bungalow](https://en.wikipedia.org/wiki/Bungalow,_Isle_of_Man "Bungalow, Isle of Man") to the highest point of the course near [Brandywell](https://en.wikipedia.org/wiki/Brandywell,_Isle_of_Man "Brandywell, Isle of Man") was named in 1981 as Hailwood's Rise, in memory of [Mike Hailwood](https://en.wikipedia.org/wiki/Mike_Hailwood "Mike Hailwood"), the former world motorcycle champion, and the highest point of the course preceding the Brandywell road junction was named [Hailwood's Height](https://en.wikipedia.org/wiki/Hailwood%27s_Height "Hailwood's Height").[\[51\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-51) In 2003 the 32nd Milestone was named Duke's,[\[52\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-52) after the 1950s world solo motorcycle champion [Geoff Duke](https://en.wikipedia.org/wiki/Geoff_Duke "Geoff Duke"), and the [26th Milestone](https://en.wikipedia.org/wiki/26th_Milestone,_Isle_of_Man "26th Milestone, Isle of Man") was named Joey's after the former Formula 1 TT motor-cycle champion [Joey Dunlop](https://en.wikipedia.org/wiki/Joey_Dunlop "Joey Dunlop"), who tallied 26 race wins. In 2013 the Isle of Man Government took the unusual step of naming corners after active competitors, with 23 times TT winner [John McGuinness](https://en.wikipedia.org/wiki/John_McGuinness_\(motorcycle_racer\) "John McGuinness (motorcycle racer)"),[\[53\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-53) and [Dave Molyneux](https://en.wikipedia.org/wiki/Dave_Molyneux "Dave Molyneux"), the most successful Manxman with 17 wins, being honoured.[\[54\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-54) The latest corners to be named have been named in honour of non-riders who have demonstrated a dedication to the TT. These include Ray Caley, former operator of the shop and post office at the junction of the course with Sulby Glen road who died in 2017.[\[55\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-55) Caley's Corner is at the beginning of Sulby Straight. In 2019 Harold Leece was recognised for his garden hospitality to TT spectators with his name on a directional marker board. Harold's corner is the 170 mph right hand bend as the riders approach Gorse Lea.[\[56\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-56) ## Safety \[[edit](https://en.wikipedia.org/w/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=10 "Edit section: Safety")\] Between 1911 and 2024 there have been 270 rider competitor fatalities during official practices or races on the Isle of Man TT Mountain Course (this number includes the riders killed during the [Manx Grand Prix](https://en.wikipedia.org/wiki/Manx_Grand_Prix "Manx Grand Prix"), and Clubman TT race series of the late 1940s/1950s). The first fatality on the TT Course was near [Glen Helen](https://en.wikipedia.org/wiki/Glen_Helen,_Isle_of_Man "Glen Helen, Isle of Man") during practice for the 1911 TT when [Victor Surridge](https://en.wikipedia.org/wiki/Victor_Surridge "Victor Surridge"), a works [Rudge-Whitworth](https://en.wikipedia.org/wiki/Rudge-Whitworth "Rudge-Whitworth") rider, crashed heavily and died of his injuries.[\[57\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-57) This was also possibly the first death in the [Isle of Man](https://en.wikipedia.org/wiki/Isle_of_Man "Isle of Man") of a person in a motorcycle or other road-vehicle accident.[\[58\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-58) [![](https://upload.wikimedia.org/wikipedia/commons/thumb/6/62/Douglas_Road_Corner_IMG_0003.JPG/250px-Douglas_Road_Corner_IMG_0003.JPG)](https://en.wikipedia.org/wiki/File:Douglas_Road_Corner_IMG_0003.JPG) The [A3](https://en.wikipedia.org/wiki/A3_road_\(Isle_of_Man\) "A3 road (Isle of Man)") [Castletown](https://en.wikipedia.org/wiki/Castletown,_Isle_of_Man "Castletown, Isle of Man") to [Ramsey](https://en.wikipedia.org/wiki/Ramsey,_Isle_of_Man "Ramsey, Isle of Man") road approaching Douglas Road Corner, Kirk Michael with safety air fencing on the outside of the bend The compulsory use of crash helmets for the [1914 Isle of Man TT](https://en.wikipedia.org/wiki/1914_Isle_of_Man_TT "1914 Isle of Man TT") motor-cycle races was the result of a fatal accident to Frank Bateman on the Keppel Gate section of the TT Course near to [Kates Cottage](https://en.wikipedia.org/w/index.php?title=Kates_Cottage,_Isle_of_Man&action=edit&redlink=1 "Kates Cottage, Isle of Man (page does not exist)") during the 1913 [Senior TT](https://en.wikipedia.org/wiki/Senior_TT "Senior TT") race.[\[59\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-59) The first introduction of a flag to signify the end of an Isle of Man TT race was as a result of a fatal accident to [Fred Walker](https://en.wikipedia.org/wiki/Frederick_James_Walker "Frederick James Walker") near to the finish line of the 1914 [Junior TT](https://en.wikipedia.org/wiki/Junior_TT "Junior TT") motor-cycle race after crashing into course boundary boards at St. Ninians Crossroads and Ballaquayle Road in the town of Douglas.[\[60\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-60) During an early morning practice session for the [1927 Isle of Man TT](https://en.wikipedia.org/wiki/1927_Isle_of_Man_TT "1927 Isle of Man TT") races, [Archie Birkin](https://en.wikipedia.org/wiki/Archie_Birkin "Archie Birkin"), brother of [Tim Birkin](https://en.wikipedia.org/wiki/Tim_Birkin "Tim Birkin") of the [Bentley Boys](https://en.wikipedia.org/wiki/Bentley_Boys "Bentley Boys") fame, crashed fatally at [Rhencullen](https://en.wikipedia.org/wiki/Rhencullen "Rhencullen") after swerving to avoid a collision with a Fish Van being driven on open roads.[\[61\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-61) From 1928 onwards, practice sessions for the Isle of Man TT Races and [Manx Grand Prix](https://en.wikipedia.org/wiki/Manx_Grand_Prix "Manx Grand Prix") were held on closed public roads.[\[62\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-62) During the first lap of the [1934](https://en.wikipedia.org/wiki/1934_Isle_of_Man_TT "1934 Isle of Man TT") Lightweight TT race, Syd Crabtree, European Grand Prix competitor and winner of the [1929](https://en.wikipedia.org/wiki/1929_Isle_of_Man_TT "1929 Isle of Man TT") Lightweight TT, crashed fatally in heavy hill fog on the Mountain section of the TT Course near to the Stonebreakers Hut on the Verandah section of the course.[\[63\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-63)[\[64\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-64) For the [1935 Isle of Man TT](https://en.wikipedia.org/wiki/1935_Isle_of_Man_TT "1935 Isle of Man TT") races, two motorcycle-equipped Travelling Marshals were employed to search for missing riders, particularly in poor weather conditions on the Mountain section of the TT Course.[\[65\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-65) After a fatal crash by [Doug J.

Changes were also made to facilitate the return of [Sidecar TT](https://en.wikipedia.org/wiki/Sidecar_TT "Sidecar TT") on the new [Clypse Course](https://en.wikipedia.org/wiki/Clypse_Course "Clypse Course"). On safety grounds, ['seeding'](https://en.wikipedia.org/wiki/Seed_\(sports\) "Seed (sports)") of competitors occurred for the 1959 TT race. The Thursday afternoon practice session from 13:45–17:00 pm introduced in the late 1950s was discontinued for the Centenary [2007 Isle of Man TT](https://en.wikipedia.org/wiki/2007_Isle_of_Man_TT "2007 Isle of Man TT") races. Also during the late 1950s, Appledene Cottage was demolished on safety grounds along with Old Brew's Restaurant near [Glen Helen](https://en.wikipedia.org/wiki/Glen_Helen,_Isle_of_Man "Glen Helen, Isle of Man") during the early 1960s accompanied by a road widening programme at [Greeba Bridge](https://en.wikipedia.org/wiki/Greeba_Bridge "Greeba Bridge"). There were six fatalities among the competitors at the [1970 Isle of Man TT](https://en.wikipedia.org/wiki/1970_Isle_of_Man_TT "1970 Isle of Man TT"), including world championship contender [Santiago Herrero](https://en.wikipedia.org/wiki/Santiago_Herrero "Santiago Herrero"), making 1970 the deadliest year in the history of the event.[\[68\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-68)[\[69\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-69) Further road safety work during the winter of 1970/1971 road-widening occurred at the Verandah series of bends and also at the [Bungalow Bridge](https://en.wikipedia.org/wiki/Bungalow_Bridge "Bungalow Bridge") by the Isle of Man Highway Board cutting into the hillside.[\[70\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-70)[\[71\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-71) Despite the safety improvements to the Verandah section, while lying in first place on the second lap during the [1972 Isle of Man TT](https://en.wikipedia.org/wiki/1972_Isle_of_Man_TT "1972 Isle of Man TT") 125 cc [Ultra-Lightweight TT](https://en.wikipedia.org/wiki/Ultra-Lightweight_TT "Ultra-Lightweight TT") race held in heavy rain, [Gilberto Parlotti](https://en.wikipedia.org/wiki/Gilberto_Parlotti "Gilberto Parlotti") crashed his 125 cc [Morbidelli](https://en.wikipedia.org/wiki/Morbidelli "Morbidelli") at the Verandah and later died from his injuries.[\[72\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-72) From 1973, any weather conditions that would not allow a rescue helicopter to take-off or land would lead to the race start being delayed or postponed at any TT or Manx Grand Prix race.[\[73\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-73) The A2 [Quarterbridge Road](https://en.wikipedia.org/wiki/Quarterbridge_Road "Quarterbridge Road") including the road junctions at Selborne Drive and Brunswick Drive and the A2 [Bray Hill](https://en.wikipedia.org/wiki/Bray_Hill "Bray Hill") were subjected to major road repairs and re-profiling during the winter of 1978/79 by the Isle of Man Highway Board. This followed a series of fatal accidents during the start of the 1978 Sidecar TT 'A' race, to the Swiss sidecar competitor Ernst Trachsel on Quarterbridge Road, and the sidecar crew of Mac Hobson & Kenny Birch on nearby [Bray Hill](https://en.wikipedia.org/wiki/Bray_Hill "Bray Hill").[\[74\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-74) For the 1979 TT races the practice of starting competitors in pairs was abandoned followed by the Manx Grand Prix in 2011 after the result of fatal crash at [Alpine Cottage](https://en.wikipedia.org/wiki/Alpine_Cottage "Alpine Cottage") during the 2010 Junior Manx Grand Prix. [![](https://upload.wikimedia.org/wikipedia/commons/thumb/d/d2/Manx_grand_prix_2010_1823.JPG/250px-Manx_grand_prix_2010_1823.JPG)](https://en.wikipedia.org/wiki/File:Manx_grand_prix_2010_1823.JPG) Competitors at the [TT Grandstand](https://en.wikipedia.org/wiki/TT_Grandstand "TT Grandstand") waiting for the start of the Newcomers Speed Control Lap (denoted by Hi-Visibility orange [tabards](https://en.wikipedia.org/wiki/Tabard "Tabard")) for the 2010 Manx Grand Prix Following a fatal accident to French newcomer Serge le Moal during the first practice session of the [2004 Isle of Man TT](https://en.wikipedia.org/wiki/2004_Isle_of_Man_TT "2004 Isle of Man TT") races,[\[75\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-75) a Newcomers Speed Control Lap was introduced for the 2004 Manx Grand Prix followed by the 2005 TT races. A mandatory TT Mountain Course licence for Isle of Man TT and Manx Grand Prix competitors was introduced for 2006. During the winter of 2004/2005 road widening by the Isle of Man Department of Transport occurred at [Windy Corner](https://en.wikipedia.org/wiki/Windy_Corner,_Isle_of_Man "Windy Corner, Isle of Man") followed by [Brandish Corner](https://en.wikipedia.org/wiki/Brandish_Corner "Brandish Corner") during the winter of 2005/2006, included a slightly banked section and a constant radius curve as a safety improvement for general road traffic.[\[76\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-76) A serious accident occurred at the [26th Milestone](https://en.wikipedia.org/wiki/26th_Milestone,_Isle_of_Man "26th Milestone, Isle of Man") during the [2007 Isle of Man TT](https://en.wikipedia.org/wiki/2007_Isle_of_Man_TT "2007 Isle of Man TT") Centenary races on lap 5 of the [Senior race](https://en.wikipedia.org/wiki/Senior_TT "Senior TT") resulting in the deaths of a competitor and two visiting spectators.[\[77\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-77) After a series of safety reviews, a number of general measures were introduced after 2007 for the Isle of Man TT races and the Manx Grand Prix and other events such as the [Southern 100](https://en.wikipedia.org/wiki/Southern_100 "Southern 100") motor-cycle races and the [Rally Isle of Man](https://en.wikipedia.org/wiki/Rally_Isle_of_Man "Rally Isle of Man"). This included the introduction of restricted areas, safety fencing and the continued introduction of air-fencing to corners to the Isle of Man TT Mountain Course. Following the start of the 2013 Senior TT race, a competitor lost control on the steep descent of Bray Hill and the racing motor-cycle collided with a wall and spectators' safety area near the junction of Bray Hill and Cronkbourne Road in the town of Douglas, injuring 11 spectators.[\[78\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-78)[\[79\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-79) During an evening practice session for the [2018 Isle of Man TT](https://en.wikipedia.org/wiki/2018_Isle_of_Man_TT "2018 Isle of Man TT"), a race competitor received serious injuries after colliding with a course inspection car near to [Ballacrye Corner](https://en.wikipedia.org/wiki/Ballacrye_Corner "Ballacrye Corner") in Ballaugh parish when travelling in a group of race competitors in the reverse course direction. The incident occurred following a red-flag incident near Sky Hill (Churchtown) after a fatal accident to Isle of Man competitor, Dan Kneen.[\[80\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-80) Following a meeting of the Strategic Motorsport Group organised by the Isle of Man Government, the Clerk of Course announced procedural changes to red flag incidents. Competitors would now wait on the course until the incident had been cleared and only travel in 'course direction' accompanied by TT Travelling Marshals at the front and rear of the convoy.[\[81\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-81) After a further legal review by the ACU in 2018 into the cause of the accident and the collision with a course inspection car a number of safety changes were initiated. This included the creation of a new event safety officer and GPS tracking to be fitted to all course inspection cars.[\[82\]](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Mountain_Course#cite_note-82) ## See also \[[edit](https://en.wikipedia.org/w/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=11 "Edit section: See also")\] - [List of Isle of Man TT Mountain Course fatalities](https://en.wikipedia.org/wiki/List_of_Isle_of_Man_TT_Mountain_Course_fatalities "List of Isle of Man TT Mountain Course fatalities") - [Isle of Man TT Races](https://en.wikipedia.org/wiki/Isle_of_Man_TT_Races "Isle of Man TT Races") - [Manx Grand Prix](https://en.wikipedia.org/wiki/Manx_Grand_Prix "Manx Grand Prix") - [Clypse Course](https://en.wikipedia.org/wiki/Clypse_Course "Clypse Course") - [St. John's Short Course](https://en.wikipedia.org/wiki/St._John%27s_Short_Course "St. John's Short Course") ## Sources \[[edit](https://en.wikipedia.org/w/index.php?title=Isle_of_Man_TT_Mountain_Course&action=edit&section=12 "Edit section: Sources")\] 1.
