Join us

Attracting over 11,000 participants and 30,000 spectators each year, this iconic triathlon has become a must-do event in the sporting calendar. With a variety of distances, routes and wave categories to choose from, everyone is welcome at the London Triathlon.

How to enter

There are two ways to join Team Macmillan for the London Triathlon 2020:

Macmillan Charity Place Entry

Our charity places are a great way to make a difference to people living with cancer. We ask that you pledge to raise a minimum of £300 in sponsorship (excluding Gift Aid) and there’s a £50 registration fee.

To enter, simply visit the London Triathlon website, choose your distance and select the 'Charity place' option.

The registration fee is payable to Macmillan Cancer Support Trading Limited which is wholly owned subsidiary of Macmillan Cancer Support. Macmillan Cancer Support Trading Limited donates 100% of its profits to Macmillan Cancer Support each year.

Own place entry

Sign up for your own place on the London Triathlon website and choose to join Team Macmillan. There's no minimum fundraising pledge, just raise as much as you can.

If you already have a place in the London Triathlon then you can order your free kit by emailing us. You’ll get all the same incredible support and you’re doing something wonderful with your personal challenge.

What do I get as part of Team Macmillan?

Whichever way you choose to join Team Macmillan, we’ll support you every step of the way with:

  • Our bumper fundraising pack, with and loads of fundraising tips and ideas.
  • Access to our online training zone .
  • Your free Team Macmillan technical running vest or t-shirt, plus iron on letters to customise your kit.
  • Regular e-newsletters to keep you up to date with Macmillan's news and activities.

Most importantly we will provide you with a reason to put in those months of training and fundraising, because you know that your efforts will help everyone with cancer live life as fully as they can.

Please make sure you read the event Terms and Conditions before signing up.

If you have any questions about the event please phone 0300 1000 200 or email

'Every time I came running round the corner on the last leg, you guys kept me going.'
