What is Tough Mudder

Probably the toughest event on the planet

Tough Mudder is a 10-12 mile mud and obstacle course designed to be a challenge that emphasizes teamwork and camaraderie.

2018 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.
