Staged in the heart of Michigan's Upper Peninsula, the Rock River Canyon ultramarathon is a 50K journey through one of the state's most remote and pristine wilderness areas. Runners traverse a fast, out-and-back course that balances moderate elevation with 'Zen quality' single-track, providing an immersive experience in the silent, ancient forests south of Munising.
