Swimathon and Open Water Swimathon
Swimming is back. Swimathon is back.
The 2021 Swimathon Festival will take place on the weekend of 10 - 12 September and will be a celebration of the return of all forms of swimming. With new distances and free entry options, this really is a swim for all! Join us for the biggest and best year yet, with close to 25,000 people set to take to the water over the Festival weekend!
Swimathon is the world's largest annual fundraising swim, taking place at 300+ pools and open water venues across the UK. There are a selection of distances and challenges to choose from, both indoors and outdoors, including 400m, 1.5k, 2.5k, 5k, Triple 5k and team challenges.
If you’re new to open water swimming, then Open Water Swimathon is ideal for swimmers of all abilities, from experienced open water swimmers to those transferring from the pool to the open water for the first time!
MySwimathon is also available, giving you the flexibility to take on your challenge within a two-week window at a location and time that suits you. This year a brand-new distance is also available to MySwimathon participants - the 30.9k!
