The London to Brighton Veteran Car Run is the longest-running motoring event in the world. The first, 1896 run — "The Emancipation Run" — celebrated the recently passed Locomotives on Highways Act 1896 which liberalised motor vehicle laws.
The run has taken place most years since its initial revival in 1927. To qualify, the cars must have been built before 1905. It is also the world's largest gathering of veteran cars – 443 started in 2005, 484 in 2009, compared to 37 starters in 1927, 51 starters in 1930 and 131 in 1938.
It takes place, currently, on the first Sunday in November and starts at sunrise from Hyde Park, London and mostly follows the old A23 road to finish at Brighton – a distance of 54 miles (87 km). There are two official stops along the way: Crawley (for coffee) and Preston Park (in a suburb of Brighton).
Preston Park is the official finishing point; the cars then proceed to Madeira Drive on the seafront, also the venue for Brighton's other big motoring event, the Brighton Speed Trials.
The event is organised on behalf of the Royal Automobile Club who emphasise that the event is not a race – they do not even publish the order in which cars finish, and participants are not permitted to exceed an average speed of 20 mph (32 km/h). Any that finish (many do not) before 4:30 pm are awarded a medal.
