New to the Swimathon family, Open Water Swimathon is an open water event happening for the first time in 2017.

The inaugural Open Water Swimathon will take place on 9th-10th September.

Cancer Research UK and Marie Curie are uniting as partners for Open Water Swimathon 2017 to raise as much money as possible for two causes close to the nation’s hearts.

Open Water Swimathon participants will have the opportunity to participate as individuals (1.5K, 2.5K or 5K) or in the team challenge (1.5K or 5K), providing the perfect challenge for both experienced open water swimmers, and those transferring from the pool to the open water for the first time.
