The steep downhill plunge riders encounter just after the start of the TT course is Bray Hill.
Bray Hill begins shortly after the TT Grandstand in Douglas, near St Ninian's crossroads, and descends toward the course's first milestone. It is one of the opening lap's defining landmarks: riders accelerate downhill before confronting a compression at the bottom and then a steep rise toward Quarterbridge.
The name refers to the hill and course section rather than a single sharp corner. That distinction explains why it is sometimes confused with Quarterbridge Road, which follows the bottom of the descent, or with other named turns elsewhere on the circuit.
Bray Hill's shape makes it technically demanding. At racing speed, suspension is heavily compressed at the dip, and motorcycles can become light over the rise afterward. The section is also one of the best-known spectator locations in the Isle of Man TT, helping make its name familiar even beyond motorcycle racing.
