The Swim Serpentine returns this year on Saturday 26th September 2020. 

Nb: Currently (05/05/2020) there are no known plans to cancel or postpone the event as a result of the ongoing coronavirus. However we are watching on a daily basis for updates from the organisers, London Marathon events for changes. 

With the event still planned, if you would like to sign-up for one of our charity places today here are the distances we places in that we need swimmers for: 

3 x 1 mile places 

2 x 2 mile places 

and for those that want to push themselves 1 x Super six place.  

How do I sign-up for Cherry Trees and how much do I have to fundraise? 

If you are interested please email: [email protected] and we can send you our registration form and fundraising materials, as well as find out more about your reasons for entering. We are a small charity and like to keep in touch with our challenge fundraisers all the way through their training, up to and after the main day. 

We ask for the following amounts to be raised for each distance:

1 mile - £250 per person

2 miles - £300 per person 

6 miles - £350 per person 

Here's a bit more information about the different swims we have places in: 

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.

PLEASE NOTE: The 2 mile swim counts towards the London Classics Medal

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.
