Toughest Mudder is 12 full hours of extreme teamwork, stamina and mental grit testing action from 8pm Saturday to 8am Sunday. Haul through as many 5 mile laps as you can while attacking 20 of the best obstacles in the industry. Tackle this beast as an individual or team up with your friends and be part of our Team Relay division.
2 & 4 Person Team Relay was put into place to open up another division within Toughest Mudder and bring more participants into the Race Series Community. Teaming up with your best friends, family members, strangers is the best way to conquer this event and help push you towards the ultimate goal of World's Toughest Mudder.
Tough Mudder is more than a mud run - it's an epic teamwork experience consisting of mud and obstacles built to test your mental grit, camaraderie and all-around physical fitness. With courses from 3 miles to 8-10 miles we have a course suited for all different fitness levels. The party doesn't stop on course, after crossing the finish line get ready to experience our Mudder Village Festival with live entertainment, authentic local eats, lawn games and all the incredible Mudder camaraderie you can handle.
