Event Description


This is it, the race of all races. One hundred miles across the high-altitude, extreme terrain of the Colorado Rockies, this event was created for only the most determined athletes. Starting at 10,152 feet and climbing to 12,424 feet, you’ll be challenged to catch your breath — while the views try to take it away.

The 100-mile out-and-back course is in the midst of the Colorado Rockies. Low point, 9,200 feet; high point is Columbine Mine, 12,424 feet. Majority is on forest trails with some mountain roads.

Please note: Due to safety restrictions on the course wheelchair participation is not permitted.
