The London to Brighton Veteran Car Run is the world's longest-running motoring event, held on a course between London and Brighton, England. To qualify, participating cars must have been built before 1905. It is also the world's largest gathering of veteran cars. The first edition, "The Emancipation Run" in 1896, celebrated the recently passed Locomotives on Highways Act 1896, which liberalised motor vehicle laws in the United Kingdom.
