Online entry for overseas swimmers will open in due course. If you are an international swimmer, you can register your interest in Swim Serpentine with Sports Tours International.
The Swim Serpentine events will take place on Saturday 16 September 2017 and will comprise a number of waves (groups). Participants will be seeded according to predicted finishing time.
Please note wetsuits are optional when the water is over 15 degrees. However, for safety reasons, all swimmers in the mass-participation event on Saturday 16 September must either wear a wetsuit or use a tow-float for the one-mile Swim Serpentine event. A small number of wetsuits and tow-floats are available in advance and a small number will also be available to hire/buy on the day.
