World's Toughest Mudder History

In 2011, World’s Toughest Mudder was created with one simple goal in mind; to find and challenge the toughest endurance athletes in the world. The format was set at a 24 hour, lap based course, to see who could complete the most laps within a 24 hour period. Each lap features the full set of signature Tough Mudder obstacles + a unique mix of obstacles designed specifically for World’s Toughest Mudder athletes. The first event was held in Englishtown, New Jersey in below freezing conditions where hundreds of athletes from around the globe turned up to compete. The conditions were harsh, but the competition was fierce and a new kind of sport was born. Along with it, a strong community of dedicated World’s Toughest Mudders turned it into an annual passion. From 2011 to 2013, the event remained in New Jersey, building new obstacles and new challenges into the format year after year.In 2013, Ryan Atkins broke the 100-mile-mark for the first time -- a feat most thought was impossible. In 2014 World’s Toughest Mudder moved from the raceway to the desert outside Las Vegas, Nevada where it remained until 2017. In 2018, World’s Toughest Mudder will take place in Fairburn, Georgia.
