177 ft gain

The courses utilize rolling, mostly wooded single track trails with beautiful lake views throughout Yankee Springs State Recreation Area. The 5K, 10K, and 25K are single loops of increasing distance, while the 50K consists of two complete 25K loops. The terrain is characterized by gentle rolling hills rather than steep climbs, making it accessible to a wide range of runners while still providing elevation challenge. The single track nature of the trails requires attention to footing, especially in winter conditions where ice, snow, or mud can create additional technical challenges. The wooded setting provides some wind protection but can also create shadowed areas where ice persists longer than on open terrain.
