Isle of Man TT (Tourist Trophy)

The Isle of Man TT (Tourist Trophy) is a motorcycle road race held each year on the Isle of Man, between Great Britain and Ireland. It was first run in 1907, making it one of the oldest motorcycle races in the world.

Since 1911 the main races have used the Snaefell Mountain Course, about 60 km of closed public roads past houses, walls, trees and a mountain section. Riders start individually at intervals and race against the clock, with classes for superbikes, supersport, sidecars and others.

The combination of very high speeds and unforgiving roadside obstacles makes the TT one of the most dangerous events in motorsport. It is no longer part of a world championship but remains hugely popular with fans, and the abbreviation TT is used for many other road races and products.
