The Gunni Grinder is an epic and very challenging 120-mile race/ride that starts and finishes in downtown Gunnison, CO. The course follows some of Gunnison County's most challenging, remote, and scenic gravel and dirt roads. If you don't have the miles but still want a challenge, The Gunni 60 (ish) and Gunni 30 will give riders a taste of what gravel riding in Gunnison County is all about. This is the 5th annual Gunni Grinder.
