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.

The Haemophilia Society (THS) is excited to offer you the chance to participate in Swim Serpentine 2025! We have secured six places in this iconic London event and we’d love for you to join TeamTHS.
