Yankee Springs Fall Festival

Yankee Springs Fall Festival is a trail running event in Middleville, Michigan, held on October 3, 2026, by Switchback Endurance. Three distances go off in staggered starts: the 50K (31 miles) at 8:00 AM, the 25K (about 15.5 miles) at 9:00 AM and the 10K (6.2 miles) at 10:00 AM, all on trails in the Yankee Springs area.

Southwest Michigan trails tend to be rolling singletrack with roots and sandy stretches rather than big climbs, which makes them good ground for a first trail race or a first ultra. The 10K is an easy entry point for newer runners and families, the 25K works well for runners who have done a road half and want to try trails, and the 50K is a classic first-ultra distance. Ten to twelve weeks of running with some hills will cover the 10K and 25K; for the 50K, plan 16 weeks with a long run reaching 22 to 26 miles and at least two back-to-back weekends. Early October usually means cool temperatures and fall color in this part of the state, so this is a comfortable time of year to race long.
