In the 2008 Summer Olympics he was selected to compete in the Men's Eight in Beijing. In the run-up to the games, he won silver at the Munich World Cup event, bronze in Lucerne, and gold in Poznań. At the Beijing Olympics he rowed in the 7 seat of the men's eight, qualifying for the final in the fastest time of either heat, 1.8 seconds ahead of the pre-games favourites, Canada. In the final, despite a late charge from Great Britain, the eight was narrowly beaten by Canada, with Langridge winning a silver medal. He was part of the British squad that topped the medal table at the 2011 World Rowing Championships in Bled, where he won a gold medal as part of the coxless four with Richard Egington, Tom James and Alex Gregory.
