London Triathlon – 22-23 July 2017

Whether you are a returning triathlete or considering taking it on for the first time, the London Triathlon is the event for you.

With five different distances, ranging from the SuperSprint (400m swim / 10km bike / 2.5km run) to the Olympic Plus (1,500m swim / 80km bike / 10km run), there really is something for people of all abilities. There are also relay options for teams of three.

We ask for a minimum sponsorship of £500 if registering just one person or £750 per team of three. Contact the fundraising team on 0208 915 6086 or email [email protected] to register your place. We can offer you:

  • fundraising pack
  • sponsorship forms
  • t-shirt or running vest
  • dedicated fundraising support and advice
  • charity support on the day.
