The Westbrook Hay Hill Climb was an annual motorsports event near Hemel Hempstead in England, where drivers competed on an uphill course.
The Herts County Automobile & Aero Club held the first Westbrook Hay speed hillclimb in 1953, and organised all events there until the course closed in 1962.
Between 1959 and 1962 the track hosted four rounds of the British Hill Climb Championship.
From the start on a gradient of 1 in 3 the road takes a fast left-hand sweep to come to a right-angled bend also to the left.
"[1] The course started just to the south of the A41[2] (today near the junction with the A4251), between Hemel Hempstead and Bourne End and climbed 650 yards up the main drive to Westbrook Hay House, today occupied by Westbrook Hay School.
