Swim Serpentine 2025
Saturday, 20 September 2025, 08:00
Release your inner dolphin and join Team WWF to take on the two-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.
The two-mile event is for those who would like to test themselves with two full laps of the Serpentine, and is aimed at more experienced swimmers who have previously completed a one-mile open water swim. The two-mile distance is also one of the three events that makes up the London Classics.
