For all open-water swimmers, this is the annual event for you! Taking place in the heart of London in truly beautiful surroundings, we have limited places in all four distances: the Half-Mile, One-Mile, Two-Mile or Super Six. We know that both the Two Mile and Super Six have sold out already so this is a great opportunity to take part. 

    All finishers will receive a medal after their swim.

    Swimming for CLEFT in this iconic event is a fantastic opportunity and is also a brilliant way to fundraise for us. We would love you to try to reach a fundraising target of £250 which you can do by setting up a fundraising page in just a few quick steps on the CLEFT website.

    How to register

    All you have to do to take part is register your details below and pay a nominal fee. The fees for each race depend on the distance you are signing up to.

    On registration, we'll send you a bright yellow CLEFT swimming hat which we hope you will wear with pride!
