Overview

edit

The Isle of Man TT is run in atime-trialformat on public roads closed to the public by anAct ofTynwald.The event consists of one week of practice and qualifying sessions followed by one week of racing. It was a tradition, perhaps started by racing competitors in the early 1920s, for spectators to tour theSnaefell Mountain Courseon motorcycles during the Isle of Man TT on 'Mad Sunday',[2]an informal and unofficial event held on the Sunday between Practice Week and Race Week.[3]In 2022, race organizers announced that beginning in 2023, racing would take place on Sunday after practices to allow visitors to see more events, marking the end of Mad Sunday.[4][5]

The first Isle of Man TT race was held on Tuesday 28 May 1907 and was named the InternationalAuto-CycleTourist Trophy.[6]The event was organised by the Auto-Cycle Club over 10 laps of the Isle of ManSt John's Short Courseof 15 miles 1,470 yards for road-legal 'touring' motorcycles with exhaust silencers, saddles, pedals and mudguards.

From 1911, the Isle of Man TT transferred to the much longerSnaefell Mountain Courseof 37.40 miles (60.19 km) (current length 37.73 miles (60.72 km)). Its elevation goes from near sea-level to 1,300 feet (400 m).[7]The race programme developed from a single race with two classes for the 1907 Isle of Man TT, expanding in 1911 to two individual races for the 350ccJunior TTmotor-cycles and theBlue Ribandevent the 500ccSenior TTrace. The race did not take place from 1915 to 1919 due to the First World War. It resumed in 1920. A 250ccLightweight TTrace was added to the Isle of Man TT programme in 1922, followed by aSidecar TTrace in 1923.

There was no racing on the Isle of Man between 1940 and 1945 due to theSecond World War.It recommenced with theManx Grand Prixin 1946 and the Isle of Man TT in 1947, with a greatly expanded format that included the new Clubman's TT races. The Isle of Man TT became part of theFIMMotor-cycle Grand Prix World Championship(nowMotoGP) as the British round of the World Motor-Cycling Championship during the period1949–1976.Following safety concerns with theSnaefellMountain Course and problems over inadequate "start-money" for competitors, there was a boycott of the Isle of Man TT races from the early 1970s by many of the leading competitors, motorcycle manufacturers and national motorcycle sporting federations.[8]

Beryl Swainbecame the first woman to compete in a TT race for solo motorcycles when she competed in the Isle of Man TT in 1962.[9]There was subsequently a ban on women in the race from 1962 untilHilary Mussoncompeted in 1978.[10][11][12][13]

The race is regarded as the most dangerous motorsport event in the world;The New York Timessaid in 2017 that the number of deaths had risen "to 146 since it was first run in 1907; if one includes fatal accidents occurring during the Manx Grand Prix... the figure rises above 250".[14][15]An account of the 2003 race bySports IllustratedwriterFranz Lidzcalled the TT "a test of nerves and speed that may be sports' most dangerous event."[16]

In 1976, the Isle of Man TT lost its world championship status; this was transferred to the United Kingdom by theFIMand run as theBritish Grand Prixfor the1977 season.The Isle of Man TT Races then became an integral part of the new styleTT Formula 1,Formula 2 and Formula 3 World Championships between 1977 and 1990 to develop and maintain the international racing status of the Isle of Man TT races.[17]

The event was redeveloped by the Isle of Man Department of Tourism as theIsle of Man TT Festivalfrom 1989 onwards. This included new racing events for the new Isle of Man TT Festival programme, including the Pre-TT Classic Races in 1989 followed by the Post-TT Races from 1991, both held on theBillown Circuit.In 2013, the Isle of ManClassic TTwas developed by the Isle of Man Department of Economic Development and the Auto-Cycle Union for historic racing motorcycles, and along with theManx Grand Prix,it formed part of the 'Isle of Man Festival of Motorcycling' held in late August of each year. The Classic TT brand ceased operation prior to the 2022 event, with classes for historic racing motorcycles integrated into the Manx Grand Prix. The TT is now promoted by the Isle of Man Government Department for Enterprise.

There has been criticism of the event. In 2007, an incident during the Senior Race resulted in the deaths of a rider and two spectators.[18]The resultant inquest made several recommendations and included several comments, such as: 'Senior Marshals may well have been elevated beyond the sphere of their competence'.[19]The coroner also noted that "I am more than aware of the fact that the witnesses from the Manx Motor Cycle Club and the marshals are all volunteers. They give their time freely and without paid reward. Having said that however, if it were suggested because they were volunteers there should be some allowance in the standards expected of them, then I regret I cannot agree."[20]

The 2020 and 2021 TT races were cancelled because of theCOVID-19 pandemic.[21][22]

Early Isle of Man TT race history (1904–1910)

edit

Gordon Bennett and Tourist Trophy car races

edit

Motor racing began on the Isle of Man in 1904 with the Gordon Bennett Eliminating Trial, restricted to touring automobiles. As theMotor Car Act 1903placed a speed restriction of 20 mph (32 km/h) on automobiles in the UK, Julian Orde, Secretary of the Automobile Car Club of Britain and Ireland approached the authorities in the Isle of Man for the permission to race automobiles on the island's public roads.[23]The Highways (Light Locomotive) Act 1904 gave permission in the Isle of Man for the 52.15-mile (83.93 km)Highroads Coursefor the 1904 Gordon Bennett Eliminating Trial which was won by Clifford Earl (Napier) in 7 hours 26.5 minutes for five laps (255.5 mi or 411.2 km) of theHighroads Course.The 1905 Gordon Bennett Trial was held on 30 May 1905 and was again won by Clifford Earl driving a Napier automobile in 6 hours and 6 minutes for six laps of the Highroads Course. This was followed in September 1905 with the first Isle of Man Tourist Trophy Race for racing automobiles, now known as theRAC Tourist Trophyand was won by John Napier (Arrol-Johnston) in 6 hours and 9 minutes at an average speed of 33.90 mph (54.56 km/h).[24]

International Motor-Cycle Cup Race (1905)

edit

For the 1905 Gordon Bennett Eliminating Trial it was decided to run an eliminating trial for motorcycles the day afterwards for a team to represent Great Britain in the International Motor-Cycle Cup Races. An accident at Ramsey Hairpin forced out one of the pre-race favourites, and the inability of the competitors to climb the steep Mountain Section of the course forced the organisers to use a 25-mile (40 km) section of the Gordon Bennett Trial course. This ran fromDouglassouth toCastletownand then north toBallacrainealong the primaryA3 roadand returning to the start at theQuarterbridgein Douglas viaCrosbyand Glen Vine along the currentSnaefell Mountain Coursein the reverse direction. The 1905 International Motor-Cycle Cup Race for five laps (125 mi or 201 km) was won by J.S. Campbell (Ariel) despite a fire during a pit stop[25]in 4 hours, 9 minutes and 36 seconds at an average race speed of 30.04 mph (48.34 km/h).[26]

Format of the races

edit

The TT Races since the first race in 1907 have been in the format of time-trial. The races held on theClypse Courseduring the period 1954–1959 were the more traditional full grid starts along with the 1924 Lightweight TT Race and Clubmen TT Races from 1948, which were also "mass-start" races. The current format is a "clutch start" and race competitors will be "started singly at 10-second intervals".[27]

For the1911 Isle of Man TT,the first TT event using theSnaefell Mountain CourseorMountain Course,two separate races were introduced. The first event was a four lapJunior TTrace and a separateSenior TTrace for 500 cc single-cylinder and 585 cc twin-cylinder motorcycles, over five laps of the new 37.5-mile (60.4 km) Snaefell Mountain Course. The new technical challenges of the Mountain Course forced changes on entrants and motorcycle manufacturers alike. The American Indian motorcycle factory fitted a two-speed gearbox and chain-drive.[32]This proved to be the winning combination when Oliver Godfrey won the 1911 Senior TT race riding anIndianat an average speed of 47.63 mph (76.65 km/h). Fitted with a six-speed belt drive[33]Charlie Collierriding a Matchless motorcycle finished second in the 1911 Senior TT race and was later disqualified for illegal refuelling.

Discontinued race classes

edit

Clubman TT and Production TT

edit

The Clubman races with Lightweight, Junior and Senior classes were held for production motorcycles from1947until1956.[36]A Senior 1000 cc class provided an opportunity forVincent motorcycles.[37]The riders were little-known, but as the stars were barred from entering the class, it provided a stepping-stone for future-stars but resulted in less spectator-interest. The series became dominated by one model – theBSA Gold Star,[38][39][40]and with little competition from other manufacturers, was discontinued. When previewing the impending re-introduction of a specification-controlled, roadster-based class in March 1967,David Dixonwrote: "lack of inter-make rivalry probably put the final nail in the coffin".[38]

Writing in UK monthly magazineMotor Cyclist Illustrated,racing journalist Ray Knight, who had achieved a lap speed of nearly 88 mph on aTriumph Tiger 100roadster-based racing motorcycle in theManx Grand Prix,[41][42][43]commented in early 1965 that theACUhad refused a request from manufacturers to run a production TT race, which he thought was a missed opportunity, particularly considering the dwindling support for the 500 cc race.[44]

Ryan Farquhar's 650 ccKawasakiat the start line of the 2012 Lightweight TT. He went on to win that year's race.

A Production TT for roadster-based motorcycles having classes for maximum engine capacities of 250 cc, 500 cc and 750 cc was introduced from1967until1976when the class was discontinued.

The Production TT was reintroduced for the 1984 races in three classes, reduced to two classes on safety grounds for the 1990 races. For the2005 racesthe Superstock class replaced the previous 1000 cc and 600 cc Production TT classes that had been part of the race schedule since 1989.

The TT Zero was a one lap race for electric bikes running from 2010 to 2019. It was announced that the race would take a two-year break after 2019, but it never came back on the schedule since.[45]

TT course official vehicles

edit

After the completion of a practice or race period, an official course vehicle displaying the noticeRoads Openproceeds around the Mountain Course, passing each point opening the roads including side-access junctions to public use. On theSnaefell mountain roadsection from Ramsey to Douglas, the official vehicle displays the noticeRoads Open One Way.

Travelling marshals

edit

Originally introduced in 1935, there are eight machines positioned around the course to provide a rapid response to any incidents. Selected riders have previous race experience and are first-aid trained, with machines carrying medical equipment that can assist in managing a casualty. They also have other duties such as course inspection, observation of machines on the course for visible faults, and review and report any course incidents.[47]As of 2023, all travelling marshals rodeHonda CBR1000RRFireblades.[48]

Crossing places during practice and races

edit

The 1982 Road Racing Act (Isle of Man) and the supplementary TT Road Races Orders allow vehicles and pedestrians to cross the Snaefell Mountain Course at certain points between scheduled race periods under the supervision of a police officer. Several permanent pedestrian overbridges have been erected. These points include:

In Douglas

  • Pedestrian overbridge at Glencrutchery Road, Douglas, close to start/finish andTT Grandstand
  • Pedestrian overbridge atBedstead Corner,Douglas, withHailwood Avenuejunction to right

  • A2 Albert Square and Princes Road,Ramseyat the junction withA18Snaefell Mountain Road, close to May Hill

TT Course access road

edit
Part of the access road passing under the A1 Peel Road

The TT Access Road runs parallel to a section of theA1Peel Road, which is part of theSnaefell Mountain Course,and operates during practice and race periods to enable vehicles to pass from inside of the race course to the outside. It runs along a section of former railway line on the historic Douglas toPeelroute, from the junction of theA5New Castletown Roadat theQuarter Bridge,passing under the course atBraddan Bridge,to an exit at Braddan School Road in Douglas outskirts, near the formerBraddan Railway Haltand theA23/Ballafletcher Road junction. The access road is a narrow,single-track widthwith passing places and is restricted to cars and light vans below a weight limit of 3,500 kilograms (3.4 long tons; 3.9 short tons). When used for vehicular traffic, pedestrian access is prohibited, but at other times it is part of a system ofnature trails.[49][50]

Incidents

edit
Main article:Isle of Man TT Mountain Course § Safety
See also:List of Isle of Man TT Mountain Course fatalities

Between 1907 and 2023, there have been 156 fatalities during official practices or races on the Snaefell Mountain Course, and 269 total fatalities (this number includes the riders killed during the Manx Grand Prix, and Clubman TT race series of the late 1940s/1950s).[14][51][52]In 2016, 5 riders died on the course during official practices or races.[53][54][15][55]There were six fatalities among competitors in the1970and2022Isle of Man TTs, making them the two deadliest years in the history of the event.[56][57][58]

2018 Course Car incident

edit
Sidecars returning toPaddockpastSarah's Cottagein reverse direction to a normal race after a red flag caused by a competitor's crash in2009

On 30 May 2018, an experienced TT rider, Steve Mercer,[59][60]was seriously injured during a head-on collision with an official Course Car atBallacrye.The car, being driven at high speed,[61][62]was conveying police officers to officiate at the scene of a fatality involvingDan Kneen.Mercer was unconscious for five days and hospitalised for five months due to multiple injuries. He was one of seven riders who had been halted on the course and turned back by marshals, being instructed to proceed back to theTT Grandstandarea in the reverse direction after thered flag stoppage.[63][64]Immediately after the accident the organisers changed their protocols, requiring that returning riders must be controlled by motorcycle-mountedtravelling marshalsto the front and rear.[65][66]An independent inquiry into the circumstances was arranged by ACU Events, the event organisers.[67]

TheAuto-Cycle Union,the Isle of Man Department for Enterprise, and the inquiry report author, lawyer Rob Jones, a former chief executive of theMotor Sports Association,all refused to release the report as it was confidential and privately owned by the ACU.[62][64][68][69]

The ACU admitted liability for the accident, but instructed that any legal claim for compensation by Mercer must be filed in the Isle of Man. The ACU stated that Mercer was receiving financial assistance through its "extensive insurance arrangements".[60][70][71]

In 2019, it was reported that the driver of the car in the collision had quit after criticism that he exceeded a newly introduced speed limit recorded by aGPS tracking devicewhen he drove to attend a fatality involving Chris Swallow atBallaughin August's Senior Classic TT. Gary Thompson, Clerk of the Course and an ACU employee, had been criticised in 2018 for also fulfilling the role of Safety Officer; consequently a new incumbent was in place for 2019.[62][72][73]

Cancellations

edit

World Wars I and II

edit

From 1915 to 1919, and 1940 to 1946, no TT events took place, due to the outbreak ofWorld Wars IandII.[74]Events continued from 1920 to 1939 and 1947 to 2000.

Since TT 1947, the Isle of Man TT has only been cancelled three times: 2001, 2020 and 2021, all of which were due to viral outbreaks.

2001 cancellation

edit

The 2001 Isle of Man TT races were cancelled because of theoutbreak of foot-and-mouth disease in the UKin the spring and summer of 2001. Disinfecting 40,000 spectators and competitors (and their motorcycles) to ensure the disease was kept off the island proved difficult.

2020 and 2021 cancellations

In March 2020, the Isle of Man Government announced the cancellation of the 2020 TT due to the ongoingCOVID-19 pandemic.[75]The Classic TT was subsequently cancelled in May,[76]and in December 2020, it was announced that 2021's TT races would also not go ahead, due to the continued worldwide spread of the virus.[77]In 2020, the Isle of Man Government lost an estimated £4.8 million of its annual projected revenue due to the cancellation of the TT races.[78]

The event returned in 2022 after a two-year absence.[79]

The Isle of Man TT was part of theFIMMotorcycle Grand Prix World Championship(now MotoGP) between 1949 and 1976. During this period the Isle of Man TT Races counted as the United Kingdom round including theSidecar TT,50 cc Ultra-Lightweight TT, 125 cc Lightweight TT, 250 cc Lightweight TT, 350 cc Junior TT and 500 cc Senior TT races counted towards the FIM Motor-Cycle Grand Prix World Championship.

After the 1972 races, multiple world champion, 10-time TT race winner and dominant motorcycle racer of his timeGiacomo Agostiniannounced he would never race again at the Isle of Man, declaring it too dangerous for international competition and that it was outrageous that such a race should ever be part of a scenario professional riders were forced into; at this point the Isle of Man TT was not suited to the growing professionalism and business aspects of Grand Prix motorcycle racing. More and more riders joined his boycott, and after 1976 the race was struck from the championship and replaced by theBritish Grand Prix.
