Tough Mudder is an endurance event series in which participants attempt 10-to-12-mile-long (16 to 19 km)[1]obstacle courses. It was co-founded by Will Dean and Guy Livingstone.[2] The obstacles often play on common human fears, such as fire, water, electricity and heights.[3]
The first Tough Mudder challenge was held in the United States in 2010,[4] on a ski hill in Allentown, Pennsylvania.[5] As of 2016, more than three million people worldwide have participated in Tough Mudder events.[6]
In January 2020, the Tough Mudder was petitioned for involuntary Chapter 11 bankruptcy by creditors Valley Builders LLC, Trademarc Associates Inc. and David Watkins Homes Inc.[7][8]
Spartan Race acquired Tough Mudder, which had been forced into involuntary bankruptcy proceedings, in February 2020. Spartan Race purchased Tough Mudder assets for $700,000 and the assumption of debts, including honoring prepaid tickets, which was approved by the bankruptcy court for the District of Delaware.[9] As of January 2024, 19 Tough Mudder events were scheduled for the remainder of the year in the United States and Canada.[10]
