Swim Serpentine 2024

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!

Trusts and Foundations

Today, 1-in-700 babies in the UK are born with a cleft lip and palate, the most common form of birth defect. The impact on a child’s life as they grow is profound. Typically, they will need at least four operations. They may also require ongoing tests, treatment or therapy. It will affect the way they look but also their speech, hearing and dental development. It can leave deep psychological scars.
