Event detail

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

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.
