Join CRUK and take on this one-day open water swimming festival staged in the heart of London.
Located in the heart of Hyde Park, at the same location that held the open water Swim at the London 2012 Olympics, the Swim Serpentine is a must-do event for all keen swimmers. Organised by the London Marathon, this is an event that guarantees a fantastic experience.
Swimming one mile is the equivalent of 64 lengths of a 25m pool. Think you're up to the challenge?
Join our team, join the fight and let’s beat cancer.
