Swim Serpentine is a one-day open water swimming event on 17 September staged in the beautiful setting of the famous Serpentine in Hyde Park, the venue for the open water swimming competition at the London 2012 Olympic Games. It is estimated that there will be around 6,000 swimmers taking part in the event this year.

Don’t miss your chance to take part. Sign up today to avoid disappointment.

  • 2 x Half-Mile Swim places: 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.
  • 2 x One-Mile Swim places: A classic distance in the world of open water swimming events. 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 at the event with swimmers taking anything from 20 minutes through to one hour to complete the swim.
