Isle of Man TT
Updated: 12/11/2025, 3:26:48 PM Wikipedia source
The Isle of Man TT or Tourist Trophy races are an annual motorcycle racing event run on the Isle of Man in May and June of most years since its inaugural race in 1907. The two week event is sanctioned by the Auto Cycle Union, which also organises the event through its commercial arm known as Auto-Cycle Union Events Ltd. The Manx government owns the rights to, and promotes the event. The Isle of Man TT is a series of time-trial format races, run on public roads closed for racing. The event consists of one week of practice and qualifying sessions, followed by one week of racing. The closed public roads form the Snaefell Mountain Course, a 37.73 mile route containing 219 turns that traverses through a mix of urban and rural areas. The event currently features 5 different classes of road racing, each competing in two races over the course of the racing week. Since the inaugural Isle of Man TT in 1907, the event has been held most every year since, with seasons being cancelled only due to war or disease outbreak. The TT has become part of the local culture and economy of the Isle of Man with more than 40,000 visitors annually traveling to the island for the event.
