Yankee Springs Winter Challenge

Welcome to the 12th annual Yankee Springs Winter Challenge! This race is run on beautiful rolling single track trails at Yankee Springs, State Recreation Area in Southwest Michigan. We run in whatever conditions Michigan winter gives us, and it's a different challenge every year. Distances are 10k, 25k, 50k, and 50 mile. The 10k is a single loop. The 25k is a single loop. The 50k is 2 laps of the 25k, and the 50 mile is 3 laps of the 25k plus a 5k loop at the beginning. Aid stations are between 2 and 4 miles apart.
