Swim Serpentine 2025

Calling all open-water enthusiasts!

Swim Serpentine is a fantastic opportunity to take on a challenge in the beautiful setting of Hyde Park’s Serpentine Lake. Whether you’re a seasoned open-water swimmer or looking for a memorable pool-to-open-water transition, this event has something for everyone.

We’d love for you to join TeamTHS at Swim Serpentine. By participating, you’ll help raise awareness and funds for a great cause, just like our incredible 2024 swimmers pictured above.
