Open Water Swimathon is returning for the third year on Saturday 7 - Sunday 8 September 2019 to help raise vital funds for Cancer Research UK and Marie Curie.

We have a range of distances available (from 500m up to 5k), which makes it the perfect challenge for both experienced open water swimmers, and those transferring from the pool to the open water for the first time!
