If you’re looking to take part or compete in an open water swimming event or race this year, then we’ve once again compiled a comprehensive list of all of the open water swimming events in Cornwall in 2020.

Some are pure swim events (with a choice of distances), whilst some are swim-run aquathlons/biathlons, or triathlons with additional run or run and cycle legs.  This year, we’ve split the list down by category, and then placed all events in date order.

If none of these dates work for you or the events don’t look suitable, then you can also create your own event/challenge by booking a private guided open water swimming session with us.
