8 Hours. Through the night.

Exclusive Obstacles...Only on

Toughest Mudder is an 8 hour obstacle course that takes teamwork, stamina and mental grit to the extreme—all between the hours of 11:59PM Saturday night and 8AM Sunday morning. With multiple regions, geographies and hardcore contenders from across the globe, Toughest Mudder is the ultimate challenge for Mudders insane enough to push themselves beyond anything they've ever experienced.

For those that want to take it one step further, the event series will act as a qualifier to make it into the Contender Category at World's Toughest Mudder (which includes eligibility for prizing).
