The Brighton Speed Trials, in full The Brighton National Speed Trials, is commonly held to be the oldest running motor race. The first race was held 19–22 July 1905 after Sir Harry Preston persuaded Brighton town council to tarmac the surface of the road adjacent to the beach between the Palace Pier and Black Rock to hold motor racing events. This stretch was renamed Madeira Drive in 1909 and the event is still held there, normally on the second Saturday of September each year. In 1936 Motor Sport described the event as: "undoubtedly the most important speed-trials on the British Calendar."

Sydney Herbert Allard was the founder of the Allard car company and a successful rally driver and hillclimb driver in cars of his own manufacture.
