Last weekend in London was Red Bull's annual soapbox race, in which competitors compete on a race track with their novelty vehicles. However, sometimes, it doesn't always work so well.
Red Bull has uploaded the below video showing some of the best crashes from the event, which took place at Alexandra Palace. Luckily, it seems, everyone walked away mostly intact.
The eventual winners of the tournament were a team called "The Breakfast Club", which was captained by Absolute Radio's Christian O'Connell. Other participants included one team which had recreated the Iron Throne from Game of Thrones and put it on wheels - and another which recreated Lego Batman.
