I want a charity place

Click the 'Get a place' button to join Team Macmillan. All of our charity places are only for the classic distance which is 8-10 miles of 25 obstacles, however if you would like to do another distance, please register directly on the Tough Mudder website.

Our charity places have a £30 registration fee and we ask you to commit to raising £300 to help support people living with cancer.

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.

Simply raise as much as you can and all the money you raise will go on to fund our vital work. Whether you're taking on the 5K distance or the classic distance, we'd love to have you on our team.
