Trail running course through mixed terrain in Michigan, USA

5K

The race is built around a 10K loop that combines approximately 5.5 miles of rolling single track with a challenging 0.7-mile ski hill segment. The 5K uses the same loop with a shortcut, positioning the ski hill climb at the end of the race. Distance runners face the ski hill multiple times: 25K participants complete one 5K loop followed by two 10K loops, while 50K runners take on the full 10K loop five times. The single track sections wind through the natural terrain around Cannonsburg Ski Area, offering typical Michigan trail conditions with rolling hills and forest paths. The ski hill segment provides the course's most significant elevation challenge, requiring runners to ascend and descend the slope that serves skiers in winter months.
