Overview

Welcome to Swim Serpentine!

Swim Serpentine is a one-day open water swimming festival staged in the heart of London.

Organised by London Marathon Events, the festival is held in and around the beautiful Serpentine in Hyde Park, the venue for the open water swimming competition at the London 2012 Olympic Games.

What’s happening

Thousands of swimmers will have the chance to swim a half mile, one mile or two miles in open water in the mass-participation event. Every swimmer will be able to choose a start wave, with swimmers setting off at regular intervals during the day.

Now in its second year, Swim Serpentine is already a must-do event in the open water swimming calendar. 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.
