Please note: we have places in HALF MILE distance only. 

Join Team WWF to take on the half-mile distance at Swim Serpentine. The popular Swim Serpentine event takes in half a lap of the world-famous lake in London’s Hyde Park. It's the perfect option if you’re looking to complete an achievable but memorable swim at your own pace, or making the transition from the pool to open water.

Entries for the half-mile distance on Saturday 16 September 2023 are now open. And by taking part in support of WWF, you’ll be helping to power our vital conservation projects across the UK and around the world. What’s more, all finishers will receive a medal after their swim, as well as a souvenir swim hat to wear on the day!
