Chillswim Windermere 11 Miles End to End 2025

The 4th Edition of Chillswim Windermere will take place on Saturday 6th September 2025. It’s the longest swim in England and a unique chance to swim the full 11 mile length with all of your swimming friends whilst knowing you are safe in the hands of the highly experienced management team at Chillswim.

There will be 7 x Start Waves at staggered times throughout the morning based on average mile pace to give you the best experience possible swimming along with other swimmers at a similar pace in the early stages, as the event progresses the waves will start to merge meaning swimmers can swim freely and unhindered at their own pace if they feel able to swim beyond the pace of their start wave. As with all Chillswim events this will be a wetsuit optional swim.
