Road Racing on the Island TT Known as the road racing capital of the world, the Isle of Man circuit is entirely made-up of public roads which are closed during Practice and Race weeks (traditionally end of May and beginning of June). During TT the population of the Island doubles and it take on a 'mardi gras' feeling. 2007 is the centenary of the start of the Isle of Man TT races, and it promises to be a bumper year, when enthusiasts and spectators from all over the world flock to the Island, to experience the 'adrenalin rush' engendered by this most exciting and hugely popular motor sport. TT (Tourist Trophy) is only one of many annual motor racing events held on other Island. For more information visit the Isle of Man TT official website. Other Exciting & Fast Events Equally exciting for motor race fans but a smaller event is the Manx Grand Prix (last 2 weeks of August) as is the Southern 100. Other popular events are The Manx International Car Rally, Stock Car Racing, the Manx Kart Grand Prix. The island further hosts an International Cycling Week. Nearly all these events and others take place across the Island during the summer months.
