About the event

Start your open water journey with Open Water Swimathon 2019 and join Cancer Research UK and Marie Curie to raise as much money as possible for two causes close to the nation’s hearts. 

Open Water Swimathon will take place from Saturday 7th - Sunday 8th September. 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!

Choose to take part in an organised session at one of our registered venues or take part at a time and place which works for you with MySwimathon.
