Conquer underground trails where history meets mountain biking adrenaline.

Miner’s Revenge takes mountain biking to new depths at Michigan's Adventure Mine, July 11-13, 2025. Riders tackle XC, Downhill, and Enduro events across rugged terrain and descend into historic copper mine shafts—racing through 300-foot-deep tunnels by headlamp. Steep climbs, rocky descents, flowing singletrack, and adrenaline-fueled mine passages make this Michigan’s most distinctive and challenging MTB event.

Multiple race options: Cross Country (XC) features 6-mile laps (1-3 laps depending on category). Downhill and Enduro events challenge riders on descents and multi-stage technical terrain. The underground mining tunnels require lights, with varied sections of steep climbs, rocky and rooty singletrack, and historic mining structures throughout the course.
