What is Tough Mudder Half

5 Miles. 13 obstacles. One extraordinary experience.

Tough Mudder Half isn’t a race -- it’s a challenge that’s all about teamwork, fun and finding out what you’re made of....

Tough is Calling. How will you answer?

Tough Mudder is no ordinary mud run - it’s an experience. An escape from the everyday. At Tough Mudder, you won’t just face your fears - you’ll knock them down. You’ll go over, around, and through them. You’ll test your strength, stamina, and grit, and you’ll help the Mudders around you to do the same.
