|WAVE NUMBER||DISTANCE||START TIME|

Swimmers with Disabilities
We will not be holding a para swimmers wave this year, but we welcome para swimmers and swimmers with a disability at any of the Children with Cancer UK Swim Serpentine events.
You will be able to choose which wave you enter when you sign up. If you require help or support on event day, please contact firstname.lastname@example.org
The event offers a safe, inclusive environment for swimmers of all abilities, who we look forward to welcoming to the Serpentine in September.
Participants with a disability can register to receive a London Classics medal if they complete the London Marathon, the Prudential RideLondon-Surrey 46 and the two-mile distance at the Children with Cancer UK Swim Serpentine.
Your Swim Pack
All participants will receive a Swim Pack before the event.
Your Swim Pack will contain the following items:
- Coloured swim hat which matches your wave colour. You must wear this hat as it displays your start wave colour. If you have a favourite swim hat that you usually swim in, you can wear this underneath your Children with Cancer UK Swim Serpentine swim hat – but please take care not to overheat if it is warm on Swim Day.
- Timing tag and strap which must be worn on your ankle. Make sure the strap is over your skin not your wetsuit, if you wear one.
- Two bands showing your name and swimmer number. One must be worn on your wrist and the other is to attach to the bag you bring along to leave at our baggage drop while you swim.
- Four numbered transfers to be placed on your body or wetsuit. These transfers will be used to identify you for your official photographs. If you do not attach the transfers, it will not be possible to identify you for your photos. A wipe will be provided at the Finish Area to remove the transfers after you swim without damaging your wetsuit.
If any items are missing from your Swim Pack, please contact email@example.com with your full name, date of birth, missing items, and postal address.
London Classics Finishers
If you are set to complete the London Classics at Children with Cancer UK Swim Serpentine, you will pick up your London Classics medal from the collection point in the Finish Area after your swim.
Wearing a wetsuit or using a tow-float
Everyone who takes part in Children with Cancer UK Swim Serpentine events must either wear a full length wetsuit or use a tow-float for safety reasons.
If the temperature of the water in the Serpentine is 15°C or above, wetsuits are optional at Children with Cancer UK Swim Serpentine. If you choose not to wear a wetsuit, you must use a tow-float.
If the water temperature is under 15°C, wetsuits are compulsory.
Water temperature guidelines
The weather in the weeks leading up to the swim will determine the water temperature.
Below is some important information on the water temperature and how it could affect your swim.
|WATER TEMPERATURE||COURSE DISTANCE||WETSUITS||MAX. TIME IN WATER*|
|15-29°C||half mile||Optional||1hr 10 mins|
|15-29°C||1 mile||Optional||1hr 40 mins|
|15-29°C||2 miles||Optional||2hr 50 mins|
|13.5-14.9°C||1 mile||Compulsory||1hr 10mins|
|13.5-14.9°C||2 miles||Compulsory||1hr 30 mins|
*Maximum time in water times have been reached based on guidance from our medical & water safety team, in line with governing body guidelines and medical evidence around swimming in water of 14°C and below. These times will be used by our team on-site to monitor swimmers still in the water, and to enable them to assess the welfare of any swimmer still in the water, exceeding these times. Swimmers may be permitted to continue swimming in excess of the maximum time in the water, providing they are assessed fit to do so by our safety team. Any swimmers showing signs of hypothermia will be asked to exit the water for their own safety and well-being.

We are happy for people even with serious medical conditions to swim, but only with their GP’s and/or specialist’s agreement. If this applies to you, please send us details of your condition and the treatment with your name and swimming number. Address the envelope to Medical Director, mark it ‘confidential’ and send it to:
London Marathon Events Ltd
P O Box 1234
London SE1 8RZ
We cannot give individual swimmers advice but are happy to advise your GP.
The Children with Cancer UK Swim Serpentine course will be clearly marked by large buoys, and a water safety team is on hand to assist any swimmers on the day if needed. All swimmers should complete their chosen distance in full while training in a pool.
Swimmers should also practise swimming in the open water before the event.
Finish times from the 2018 edition of Swim Serpentine are now available to view.
Age Group Prizes
The mass participation events are not races, with the main focus on fun. However, specially designed age group medals will be mailed out post-event to the top three male and female finishers in the following age group categories:
One and Two-Mile Swims: 16-24 years old, then 10-year age bands starting at 25 years old.
The Half-Mile Swim is a fun event, although the top three male and female finishers in the 12/13 and 14/15 age categories, who are unable to enter the longer events, will also be awarded medals.
