Course Description
Both the 3.5 & 7.5-mile racecourses follow predominately single-track mountain bike and hiking trails. The Courses offer a lot of twists, turns, and elevation changes to challenge runners as they wind through and around the densely wooded hills and prairie along the Big Sioux River. Runners for both races will start near Oak Grove Lodge and quickly dive into wooded single track. The 3.5-mile course and the 7.5-mile course split at about 1 mile into the race with the 7.5-mile course rejoining the 3.5-mile course at about 5 miles. Both race distances will finish back at the Lodge where post-race refreshments will be available.
