Lock 2 Lock 10K 2025

Join us for a breathtaking 10K wild swimming event in the stunning upper Thames area, surrounded by nature's beauty. You'll encounter 3 locks along the way, each equipped with convenient feed stations. Our comprehensive support includes safety crews, medics, and power rescue boats for your peace of mind.

Immerse yourself in open water swimming amidst the river's natural habitat, complete with wildlife, trees, and fellow river enthusiasts. It's all part of the event's charm, but remember to prioritize safety and watch out for one another. We're excited to assist you throughout this epic journey.

Prior to registering, ensure you have the necessary swimming skills and experience for this distance. If you intend to swim without a wetsuit (skins), please contact us first.

We can't wait to meet you. Thank you!
