Tough Mudder X is the most insane race around, created to disrupt the sports industry. This is the ultimate race to determine the fittest, fastest athletes in the world. This pulse-pounding competition pits the world’s elite athletes against a one-mile course built to put speed, agility, and strength to the test with world-class obstacles and challenging workouts. Tough Mudder X will push good to great, better to best, and The Toughest Athletes on the Planet beyond their limits.

You saw it on TV, now is your turn to take on The Toughest Mile on the Planet, with Tough Mudder X Open.

Tough Mudder X Open is your chance to test your mettle against The Toughest Mile on the Planet. This open event is for any Mudder tough enough (and crazy enough) to tackle a mixture of epic obstacles, workout zones, and a one-mile course so wild it pushed The Toughest Athletes on the Planet to their limits. Individual male, female, and Team Relay winners will be crowned, and should you top the podium at your event, you’ll earn a spot on course to battle head-to-head against those very same Toughest Athletes on the Planet in the Tough Mudder X Championship.
