The Chillswim Windermere 11 Miles End to End is a premier open water swimming event set in the picturesque Lake District. Scheduled for Saturday, September 6, 2025, this swim offers participants the opportunity to traverse the full length of Windermere, starting at Fell Foot Park in the south and finishing at Waterhead in the north. The route is approximately 11 miles (17.7 kilometers) long, with swimmers keeping within approximately 50 meters of the shore after the first 2 miles.
Participants can choose between the Suits category, which allows wetsuits for added buoyancy and warmth, and the Skins category, which requires swimming without a wetsuit. The event includes feed stations at 1-mile intervals along the route, stocked with water, energy drinks, and jelly babies to keep swimmers energized. A professional water safety team will be present throughout the swim to ensure participant safety. Each swimmer receives a Chillswim Windermere silicone event swim hat, a bespoke event medal, and a Chillswim Windermere event hoody upon completion. Age group trophies are awarded in both wetsuit and non-wetsuit categories. The entry fee is £225, which includes transport to the start from the race headquarters at Rydal Showground, Ambleside, free parking on race day, and all event amenities. Please note that a mandatory tow float/dry bag is required for all participants, and the entry fee does not include the cost of the tow float.
For those interested in discounted charity entries, a fundraising target of £250 is required, with the entry fee reduced to £49. The event is open to swimmers aged 16 and over. Please note that the entry fee does not include the cost of the tow float.
