The Tough Mudder is a 12-13 mile obstacle course designed by British Special Forces to test a participant’s all-around strength, stamina, mental grit and camaraderie.
The worldwide event was founded by Will Dean, a former counter-terrorism agent for the British government. While working on his master’s degree at Harvard, Dean created Tough Mudder because he was looking for a challenge that marathons, triathlons and other adventure runs did not offer.
Started in 2010 with just three races, there were 35 Tough Mudders held in 2012. The event has seen more than 700,000 people participate in a course that features anywhere from 25 to 30 obstacles, ranging from the Artic Enema, to the Ball Shrinker, Dirty Ballerina, Electric Eel and the Turd’s Nest, just to name a few. According to the group’s website, it is “the premier adventure challenge series in the world.”
The group has also raised more than $5 million for the Wounded Warrior Project by offering a discount off the registration fee for any participant who pledges to raise $150.
