Tough Mudder is an endurance event that tests mental and physical strength over 10-12 miles of military-style obstacle courses.
The company was founded in 2010 by two British Harvard Business School students, Will Dean and Guy Livingstone. The concept was developed by the pair as part of an annual business plan competition, where it won an honorable mention.
Tough Mudder courses features over 20 obstacles including live wires, butter-slicked monkey bars over a pit of cold water, a dumpster filled with ice water, a 8-12 wall to scale, narrow pipes and mud, and a high jump. The company emphasizes teamwork and participants must help others complete the course.
Tough Mudder has had more than 1.3 million people worldwide participants in events since its founding in 2010.
The company is #65 in the 2014 Inc. 5000 list of Fastest-Growing Private U.S. Companies with a three-year growth rate of 4,738% and $107.9 million in revenue in 2013.
