Our open water swim challenge has a range of distances, which you can swim as an individual or as part of a team. This challenge is open to all swimmers whether you are a seasoned pro and can manage longer distances or you have only swum in a pool before but always fancied dipping into open water. Not only will you be swimming in tranquil surroundings, but also engaging in an activity that has so many incredible health and wellbeing benefits.

All participants will receive a swim hat, medal and free hot drink on the day.
