Event detail

  • Various UK Locations
  • Multiple dates

 Tough Mudder London West, Midlands and Scotland have been postponed until the autumn. The Yorkshire, Midlands and South West events have been postponed to 2021. 

We are so grateful for your commitment, resilience and amazing support. In the current climate, people living with Crohn’s and Colitis are relying on our services more than ever – and, because of our incredible fundraisers, like you, we’re able to be here for more of those affected by these conditions. Thank you.

We very much look forward to a fantastic event series later in the year. We’ll be in touch soon, but if you have any questions in the meantime, please do get it touch with us.

We will be opening registrations for the 2021 Tough Mudders later in the year. Email us to let us know that you are interested in joining the 2021 team, and we'll get in touch once registrations are open.

Do you love a good challenge and want to try something new?

Why not sign up to take part in the ultimate muddy obstacle challenge, Tough Mudder! 

The courses are designed to challenge physical strength and mental grit, and are best tackled as part of a team, so you can sign up with friends before you go or of course meet new friends at the foot of each obstacle.

We have Charity Places avaliable in all of the ‘Classic’ events, which are 8-10 miles and have 25 obstacles.  

Check below to find your nearest event:

North West: 5th & 6th September

London South: 19th & 20th September

Scotland: 3rd & 4th October

We ask all our charity place runners to pay a £50 registration fee and to commit to raising a minimum of £350 in sponsorship.

Part of a team of 5 or more of you looking to do Tough Mudder? To sign up as a team, and recieve 20% off your registration fee and a team fundraising target choose Charity Place - Team of 5 or more when you sign up.

If you already have a place in a Tough Mudder event, whatever the distance, we would love to have you join our team as an Own Place participant - choose Own Place when you sign up.

After 3.5 hours I was glad to reach the finish line, feeling very tired and bruised, but absolutely euphoric at being able to complete the course and most importantly raise money for Crohn’s & Colitis in the process. Knowing it was for a great cause definitely helped carry me through the course.
