Swim Serpentine London

September 16, 2017



Entries are now open for the new events that have been added to Swim Serpentine, the open water swimming festival that will return to Hyde Park on Saturday 16 September 2017.

Swimmers now have the choice of a half-mile and two-mile swim, in addition to the hugely popular one-mile mass-participation swim which returns for the second year of the event.

In addition, the organisers have created the Swim Serpentine Super Six challenge, which offers the chance for swimmers to take on the challenge of swimming a total of six miles in five different races during the day.

“We have added these new events to the Swim Serpentine programme so that swimmers of all ages and abilities can enjoy open water swimming in the spectacular setting of the Serpentine,” said Hugh Brasher, Event Director. “In 2017, we look forward to welcoming swimmers from the age of 12 in the new half mile event and the very experienced open water swimmers who take on the Swim Serpentine Super Six challenge.

“With thousands of swimmers participating in the mass participation one mile events plus the great free family festival around the lake, it’s going to be a fantastic day.”

The new events are:

  • Half mile: entry fee £25.00 (minimum age 12 on 16 September 2017)
  • Two miles: entry fee £49.00 (minimum age 16)
  • Super Six: entry fee £150.00 (minimum age 18)

The entry fee for the one mile event is £39.00 and the minimum age for entry is 16 on the day.

Up to 6,000 swimmers will be accepted for the one-mile mass-participation event. Every swimmer will be able to choose a specific start wave which go off at regular intervals during the day. Wetsuits or tow floats are compulsory in all events. Both wetsuit and tow-float hire will be available beforehand and at the Serpentine on the day.

Online Entry

Entering Swim Serpentine

Online entry for all events at Swim Serpentine is now open. Entry is on a first come, first served basis so enter now to avoid disappointment.

Entries for all events close at 17:00 on Thursday 27 July 2017.

Half-Mile Swim

This distance is an ideal entry level open water swim. Taking in half a lap of the Serpentine, there is plenty of time to swim this distance at your leisure with a friend, race your mum or dad or just to try out an open water swimming event with an achievable but for some still challenging swim.  Numbers are limited for this event, which will be held in the morning of Swim Serpentine, so don’t delay.

Half Mile Entry

Entry costs £25. Entrants must be at least 12 years old on Saturday 16 September 2017.

One-Mile Swim

A one-mile swim is a classic distance in the world of open water swimming events. Swim Serpentine takes place on the same course as the London 2012 Marathon Swimming Olympic event, with one full lap around the Serpentine making up the one-mile swim. This is the most popular of all the swim distances for Swim Serpentine with swimmers taking anything from 20 minutes through to one hour to complete the swim.

One Mile Entry

Entry costs £39. Entrants must be at least 16 years old on Saturday 16 September 2017.

Two-Mile Swim

For those who would like to test themselves with two full (1.6km) laps of the Serpentine. Aimed at more experienced swimmers who have already completed a mile open water swim previously. A challenging two-lap swim set in a beautiful location: what’s not to like?

Two Mile Entry

Entry costs £49. Entrants must be at least 16 years old on Saturday 16 September 2017.

Super Six

Swim six miles with a combination of one-mile and two-mile events during the day. All the ‘Super Sixers’ will start in the same one-mile wave, then how you complete the total distance is up to you. Choose to swim event after event, or take a break before you continue on with your swim.

Don’t underestimate this challenge – swimming for 10km straight is one thing, but the challenge for this swim is that the swimmer must to get out the water between each one or two-mile swim and wait for the next event to start, which makes this a tough challenge for any experienced swimmer. But with a special coloured swim hat for the Super Sixers and very limited spaces available, you’ll be treated like a true ‘Super (Six)’ Hero for the day.

Entry costs £150 and is limited to 60 swimmers. Entrants must be at least 18 years old on Saturday 16 September 2017.

Elite One-Mile Invitational Race

Entry into the Elite One-Mile Race is by invitation only. If you would like to be considered, please email Colin Hill at colin.hill@londonmarathonevents.co.uk

Elite entries are limited to 25 male and 25 female competitors. The minimum criteria from which the swimmers will be selected is 16:10 for the men (1500m time) and 9:00 for the women (800m time) or swimmers with international open water racing experience at FINA or LEN level.

There will also be an Elite Para One-Mile Invitational Race. Para swimmers should have international experience in the pool or triathlon and are selected by the Para elite manager.

Wetsuit & tow-float hire

Wetsuits are optional when the water temperature is over 15 degrees. However, for safety reasons, all swimmers must either wear a wetsuit or use a tow-float for all Swim Serpentine events.
