Registration opens for 2023 Swim Serpentine

At noon on Thursday 8 June, 2023 Swim Serpentine opened for registration and within two hours, spaces had almost all sold out. 

When entries for Swim Serpentine 2023 went on sale Thursday 8 June, not even organisers expected the incredible demand for places, possibly due to the event being postponed in 2022. 

At the time of writing all of the two-mile waves and mixed one-mile waves were full. Spaces remained for the women-only one-mile wave and the half-mile wave.  Charity places will be released in the coming weeks, so there are alternative ways you can enter if you missed your chance to register for this year’s event!

Swim Serpentine, one of the UK’s largest outdoor swimming events, returns to Hyde Park on Saturday 16 September. It’s the first time the event has been held since 2021, after last year’s event was postponed due to preparations for the State Funeral of HM the Queen in Hyde Park. 

Everyone who signed up for the 2022 event was offered a guaranteed place for this year, with 1,500 new entries made available across four distances: half-mile, one-mile, two miles and the Super Six (a six-mile swim open to anyone aged 18 and over). 

Swim Serpentine is a legacy event from the 2012 London Olympic games. First held in 2016, it attracts participants from all walks of life to explore open water swimming in a fun, safe and welcoming environment.  

Take part in the London Classics challenge

The two-mile event at Swim Serpentine is part of the London Classics challenge, along with the London Marathon and RideLondon 100. Anyone who completes all three iconic events is rewarded with a special London Classics medal and a place in the Hall of Fame. This year, a record number of people are set to complete the London Classics and receive their finisher’s medal at Swim Serpentine.

2023 Swim Serpentine takes place on Saturday 16 September. Find out more about the event and sign up here.
