Built on and around one of America’s most-storied racetracks, Michigan International Speedway is no stranger to adrenaline and high-stakes glory. Featuring murky wetlands, meandering trails and jaw-dropping surprises courtesy of our mad-minded Course Designers, only the Toughest Mudders will see the checkered flag in this Great Lakes giant.
Spectator registration is available online for $20 until Friday (Sept 19) at midnight before event weekend. If you miss the online registration deadline, spectator tickets will be sold for $40 on site.
Join our team of Tough Mudder Volunteers (MVPs) and create a life-changing experience for yourself and others. Or, if you’re participating, get your supporters (who are ready for the mud, but not the electric shocks) to volunteer so they can still be part of your day. As an added perk, our MVPs get up to 90% off registration.
All participants and spectators must sign a waiver in order to enter the event. Anyone under the age of 18 must have a parent or guardian sign a waiver for them.
