Half-mile swim

Take on the half-mile swim at Swim Serpentine

We’d love to see you take on the half-mile distance at Swim Serpentine! This event features half a lap of the world-famous lake in London’s Hyde Park and is a great option if you’re looking for an achievable but memorable swim at this iconic venue.

Choose the half-mile distance and you’ll have plenty of time to swim at your leisure with a friend, race the other speedy entrants, or simply try an outdoor swimming event if you’re making the transition from the pool to open water.

Medal and souvenir swim hat for every finisher

All finishers will receive a medal after their swim, as well as a souvenir swim hat to wear on the day!

Swimmers with disabilities

Our team works to support participants with a range of disabilities to ensure Swim Serpentine offers a safe, inclusive environment for swimmers of all abilities.

If you need assistance to feel safe and confident at the event, we’ve put in place a number of measures to help, including:

ramped entrance into and exit out of the Serpentine
assistance with entering and exiting the water
accessible toilets and changing facilities

Please note that you do not need to enter a specific wave at the event to receive support.

If you have any further questions about the disability support available at the event, or need any additional support, please email disability@londonmarathonevents.co.uk and we’ll be in touch.

Swimmer safety at Swim Serpentine

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.

The Festival

Alongside the open water events at Swim Serpentine, the free Festival will feature a range of stands offering essential kit (such as wetsuits and tow floats) to enhance your open water swimming experience, as well as talks from inspiring speakers and an opportunity to interact with wild swimming enthusiasts just like you!
