Taking in half a lap of the Serpentine, there's plenty of time for you to complete this achievable, but for some still challenging, swim. It is also a great opportunity try out open water swimming if you're new to the sport.

Your safety is our number-one priority at Swim Serpentine, so our water safety team will be standing by to assist on the day. The Swim Serpentine course will be clearly marked by large buoys, so you’ll find it easy to make your way around your chosen swim distance.

It’s a good idea to complete your chosen distance in full in a pool before the event, and also to practise swimming in open water beforehand, so you have the best possible experience at Swim Serpentine.
