What Makes It Great

The Sangre de Cristo 50K covers 33 miles of Rainbow Trail singletrack entirely above 9,000 feet in the southern Colorado Rockies. With 7,600 feet of climbing and a 16-hour cutoff, the course follows the wilderness boundary to a turnaround at Macey Creek before returning to Music Meadows Ranch. No crew or pacers are permitted — this is a self-reliant mountain running challenge in a genuinely remote setting. Starts at 6 AM alongside the 50-mile field.
