The Isle of Man TT (Tourist Trophy) Race is an annual motorcycle event held on the streets of the Isle of Man. The TT was for many years the most prestigious motorcycle event of the year, and some argue it still is. Originally starting out in 1904 with four wheels, the event has progressed and increased in size ever since, with various different layouts, and lengths, the only main similarity to the original is the location! For many years the event was part of the FIM Motorcycle Grand Prix World Championship during 1949-1976, which was the last official GP held. The event moved to the UK, due to the increasing worries over safety. Even with this loss, the TT continued, and to an extent has become stronger because of it. Now, amatuers can enter, and race at speeds well in excess of 200mph, with very little in the way of safety! Looking at the lap, it is over 60KM long, and is around the island, going up and through the mountains.
