The International Isle of Man TT (Tourist Trophy) Race is a motorcycle racing event held on the Isle of Man and was for many years the most prestigious motor-cycle race in the world. The event was part of the FIM Motorcycle Grand Prix World Championship during the period 1949–1976 before being transferred to the United Kingdom after safety concerns and run by the FIM as the British Grand Prix for the 1977 season. The Isle of Man TT Races became part of the TT Formula 1 Championship during the period 1977–1990 to preserve the event's racing status. From 1989 the racing has been developed by the Isle of Man Department of Tourism as the Isle of Man TT Festival.
The race is run in a time-trial format on public roads closed for racing by the provisions of an Act of Tynwald (the parliament of the Isle of Man). The first race was held on Tuesday 28 May 1907 and was called the International Auto-Cycle Tourist Trophy. The event was organised by the Auto-Cycle Club over 10 laps of the St John's Short Course of 15 miles 1,470 yards for road-legal touring motor-cycles with exhaust silencers, saddles, pedals and mud-guards.
The winner of the single-cylinder class, and overall winner of the first event in 1907, was Charlie Collier riding a Matchless motor-cycle in a time of 4 hours, 8 minutes and 8 seconds at an average race speed of 38.21 mph. The winner of the twin-cylinder class was Rem Fowler riding a Peugeot engined Norton in a time of 4 hours 21 minutes and 52 seconds at an average race speed of 36.21 mph. The trophy presented to Charlie Collier as the winner of the 1907 Isle of Man TT Race, was donated by the Marquis de Mouzilly St. Mars. It featured a stylised version of Olympic God Hermes by Giovanni Da Bologna as a silver figurine astride a winged wheel. The trophy was similar in design to the 18 carat gold Montague Trophy presented to John Napier (Arrol-Johnston) as the inaugural winner of the Isle of Man Tourist Trophy car race in 1905 now known as the RAC Tourist Trophy. The Marquis de Mouzilly St. Mars Trophy is now presented annually to the winner of the Isle of Man Senior TT Motor-Cycle Race.
The 2007 Isle of Man TT was the Centenary event which ran between 26 May and 8 June 2007 and featured a special Re-enactment of the 1907 Isle of Man TT Race held on the village green next to Tynwald Hill in St John's on Monday 28 May 2007. The vintage parade of 100 classic motor-cycles for the Centenary Re-enactment on the original St John's Short Course was flagged away by former World Motor-Cycle Champion Geoff Duke. The first of the participants to be flagged away was the recently restored twin-cylinder Peugeot-Norton ridden by Rem Fowler during the first Isle of Man TT Race in 1907. Also participating in the 2007 Re-enactment was TT race competitor Guy Martin riding a 1938 Triumph Tiger 100 500cc and other former TT competitors including Alan Cathcart, Sammy Miller, Nick Jefferies and Mick Grant also completed the Re-enactment lap.
