High Lonesome 100

The High Lonesome 100 is a high flying endurance race in the Sawatch Range of the Colorado Rocky Mountains. With 23,500′ of vertical gain, reaching an elevation of 13,150′, it’s a hell of a course. The race runs in a loop through some of the most beautiful singletrack in the state, and takes runners on the National Continental Divide and Colorado Trails, through two ghost towns, over five alpine passes, through remote basins, over soaring ridges, all in 37 hours.
