Overview
The Isle of Man TT (Tourist Trophy) is the world's oldest and most legendary motorcycle road race, first held in 1907. The event takes place annually on the Isle of Man, a self-governing British Crown Dependency in the Irish Sea. The race is run on the 37.73-mile (60.7 km) Snaefell Mountain Course — public roads closed for racing.
The TT is known as the most dangerous motorsport event in the world, with over 270 fatalities since its inception. This immense risk is matched by unparalleled bravery and skill, making TT racers a unique breed in motorsport. Average speeds exceed 130 mph (209 km/h), with top speeds over 200 mph (320 km/h).

- Bray Hill: First major test, a treacherous high-speed descent
