The Dirty Mitten

The Dirty Mitten Gravel Bike Race 2025 is a high-energy gravel cycling event set in Michigan’s scenic backcountry, featuring three distances—10, 28, and 50 miles. Taking place on September 20, 2025, as part of the Dirtfest Weekend, this race offers an exciting mix of rolling gravel roads, wooded trails, and open countryside for cyclists of all skill levels. With well-marked routes and fully stocked aid stations, riders will experience Michigan’s stunning landscapes, including dense forests, quiet dirt roads, and rugged off-road sections. Whether you’re racing the fast-paced 10-mile loop or pushing yourself on the grueling 50-mile course, The Dirty Mitten promises a challenging yet rewarding ride. For those looking to double the challenge, The Dirty Double allows participants to race both Saturday and Sunday, competing in either the Trail Run + Gravel Bike Race or the Gravel Bike + Gravel Triathlon. Whether you’re riding for fun or pushing for a podium finish, The Dirty Mitten 2025 is the ultimate gravel experience in Michigan!
