This event sees thousands of swimmers taking to the water in Hyde Park’s famous Serpentine Lake. In 2018, a record breaking 6,000 people of all ages and abilities entered this inspirational open water swimming event that includes half-mile, one-mile, two-mile and 'Super Six' swims.

All your needs are catered for with heated changing rooms, dunk zone, pontoon start and finish, full water safety crew, hot tubs and exhibition area. It's a family day, so bring everyone along to give their support and cheer you on! 

We have places for the 1 and 2 mile swims this year. The 2 mile swim counts towards The London Classics medal

The London Classics requires participants to complete the London Marathon, the RideLondon-Surrey 100 and the two-mile event at Swim Serpentine (in any order and over any given time period). Everyone who completes the three events receives the magnificent London Classics medal, engraved with the words Et Ego Londinium Vici (I too have conquered London) and is listed in the Hall of Fame.

The Swims

Half-Mile Swim:Taking in half a lap of the Serpentine, there is plenty of time to swim this distance at your leisure with a friend, race your mum or dad or just to try out an open water swimming event with an achievable but for some still challenging swim.

One-Mile Swim:A classic distance in the world of open water swimming events. The Children with Cancer UK Swim Serpentine takes place on the same course as the London 2012 Marathon Swimming Olympic event, with one full lap around the Serpentine making up the one-mile swim. This is the most popular of all the swim distances for the Children with Cancer UK Swim Serpentine with swimmers taking anything from 20 minutes through to one hour to complete the swim.

Two-Mile Swim:For those who would like to test themselves with two full (1.6km) laps of the Serpentine. Aimed at more experienced swimmers who have already completed a mile open water swim previously. A challenging two-lap swim set in a beautiful location.

Super Six Swim: For swimmers who can’t get enough of the open-water experience, there’s an opportunity to swim six miles at the Children with Cancer UK Swim Serpentine, broken down into one- and two-mile swims during event day.
