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 thrilled to offer you the opportunity to participate in Swim Serpentine 2025! We have secured six spots in this iconic London event and would love for you to join Team THS. By taking part, you’ll help raise awareness and funds for an important cause, just like our amazing swimmers from 2024, who are pictured above.
