Isle of Man TT Mountain Course (Snaefell Mountain Course), Racing Circuit

The Snaefell Mountain Course is the most storied venue in road racing: a 37.73-mile (60.72 km) lap stitched together from ordinary public roads that are closed for racing, running clockwise out of Douglas and up over the slopes of Snaefell, the island's highest peak. Motorcycle racing on the Isle of Man dates to 1907, and this Mountain configuration has been used since 1911, growing into the spiritual home of the sport. A lap threads through villages such as Union Mills and Crosby before the long climb across the Mountain and the plunge back to the start at the Grandstand on Glencrutchery Road, taking in landmarks every fan knows by name: the screaming drop of Bray Hill, the leap at Ballaugh Bridge, the tight Ramsey Hairpin, the flat-out Mountain Mile, and the right-hander at Creg-ny-Baa. With more than 200 corners, walls, kerbs and unforgiving scenery, it is also the most dangerous circuit in racing, having claimed well over 250 lives across its history. The outright lap record belongs to Peter Hickman, who in 2023 circulated at an average of 136.358 mph. The course stages two annual fixtures: the Isle of Man TT in late May and early June, and the Manx Grand Prix and Festival of Motorcycling in late August.
