Swim Serpentine

Swim Serpentine within Hyde Park is a one-day open water swimming festival staged in the heart of London. 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!

Join team Rainbow Trust for either the Half Mile or Super Six event, and help raise vital funds to support families caring for a seriously ill child.

We work hard to ensure our swimmers have a memorable experience - you’ll be supported all the way to the finish!
