Overview

Swim Serpentine is the UK’s most iconic swimming festival

Swim Serpentine is an open water swimming festival held in the famous Serpentine lake in London’s Hyde Park.

First held in 2016 as a legacy event from the 2012 London Olympic Games (the Serpentine hosted both the triathlon and open water swimming events during the Games), Swim Serpentine invites participants to take on four distances: half mile, one mile, two mile and six miles (known as the Super Six).

Swimmers are split into a series of waves that take place in the Serpentine throughout the event day. Participants can be aged from 12 upwards with many taking on the challenge to raise money for charity.
