Help us fund the fight. Together we will find a cure.
Join 6,000 swimmers for this open water, mass participation event. Swimmers will set off in waves throughout the day to complete their one-mile distance.
All swimmers in the mass participation mile must wear either a wetsuit or use a tow-float. Both wetsuit and tow-float hire will be available at the Serpentine on the day.
Charity places have closed now. However if you have your own place we would love to have you swim on our behalf! Register below to let us know you are taking part!
