Bike Course

Both bike races start from the Visitor’s Center inside Norris Dam State Park. After hitting some of the single track trails on the West side of the park, riders will take US Highway 441 across the iconic Norris Dam and enter into the Norris Watershed on the East Side. The old road beds and contour cuts will take riders on a leg busting journey through the natural topography and beauty of the area before returning back across Norris Dam to finish the remainder of the trails in the State Park. Covering approximately 31 miles, the long course is a monster. The short course will also cross Norris Dam and explore a lot of the same trails as the long course, but with less climbing and distance.

Course maps are coming soon. Check back for updates.
