When it comes to support there's no competition. Team Macmillan is looking for budding triathletes to take part in this exciting event. With a variety of different races there is an event to suit everyone from complete beginners to experienced athletes.

Whether you want to compete in the sprint distances or as a team round the docklands or take on the Olympic distance all the way to Big Ben via Tower Bridge, it promises to be a spectacular event and a race to remember.

Here at Team Macmillan we understand what it takes to train for and complete a triathlon. So we'll be there for you from the start providing both fundraising and training advice. We'll prepare you for the big day with fundraising advice and top tips and we'll be there cheering you on from our supporter point.

By pulling on the green vest and becoming a part of Team Macmillan you will be helping us to provide immediate practical, emotional, medical and financial support that will change the lives of people living with cancer in the UK today, as well as joining the friendliest and most supportive team in the race.

So, if you're planning to sign up and swim, cycle and run your way round the world's most popular triathlon, now is the time to do it!
