Join Macmillan for the largest triathlon in the world. There are two methods to apply for the London Triathlon, you can either use your own place to run for Macmillan, or you can apply for one of our limited number of Team Macmillan Guaranteed Places.

London Triathlon has now filled all its places.

Got a place? If you managed to secure your own place through the official entry system then we would love you to be part of Team Macmillan. Simply fill in our online form and we will provide you with a full Fundraising Pack including your free running vest, regular newsletter updates and the loudest support on the day. Most importantly we will provide you with a reason to put in those months of training and fundraising, because you will know that your efforts are going towards improving the lives of people living with cancer in the UK today.

Need a place? You can apply for a Team Macmillan Guaranteed Place, for which we ask for a minimum sponsorship pledge of £500. Simply complete and return our Team Macmillan application form [pdf] as soon as possible. If you would like to be sent a postal copy of the application information please fill in the online form.
