About This Race

The Yankee Springs Winter Challenge embraces the unpredictability of Michigan winters, running its 15th edition on rolling single track trails at Yankee Springs State Recreation Area. This established January race offers four distances from 5K to 50K, each designed to test runners against whatever conditions winter delivers. The race draws its character from the variability of the season—runners might face snow, ice, mud, or even bare trails, making each year a unique challenge. The courses wind through beautiful wooded terrain with lake views, offering a scenic backdrop to winter trail running. Aid stations are strategically placed every 2-4 miles on longer distances, providing consistent support through the rolling terrain. The race maintains a welcoming atmosphere with post-race food served in a heated tent, creating a warm gathering point after cold miles on the trail. Organized by Switchback Endurance, the event has built a reputation for reliable organization and consistent course quality over its decade-and-a-half history. The 50K distance allows pacers on the second loop, adding strategic elements for ultrarunners tackling the longest distance in winter conditions.

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.
