MTB 65 is part of the Cohutta Races, an annual endurance mountain bike series centered in Copperhill, Tennessee. The series offers riders three distances: the Cohutta 100, the Big Frog 65, and the Old Copper 30.
The race headquarters is the pavilion at the former Ocoee Whitewater Center. The course includes fast, flowing singletrack, singletrack descents, some pavement, and gravel road sections, providing varied terrain beyond a continuous trail grind.
