The Gunni Grinder is 120-miles of pure Colorado gravel grit. Starting and finishing near downtown Gunnison, this course throws down some of Gunnison County’s toughest, most remote, and jaw-dropping dirt roads. Big climbs. Big miles. Big views. This is backcountry gravel at its finest.
Not ready to go full send? The Gunni 60ish and Gunni 30 still bring the heat. Challenging, scenic, and seriously fun, these routes deliver a true taste of Gunnison County gravel without the full 120-mile commitment.
Choose your distance. Embrace the grind. Ride Gunnison.
