High Lonesome 100

The High Lonesome 100 is a high-flying Colorado mountain race transecting the southern end of the expansive Sawatch Range. Starting and ending at the base of Mount Princeton, the loop course takes runners along soaring ridges, through idyllic meadows and remote basins, across 5 alpine passes, and through two ghost towns. Runners will be treated to 27 miles of the National Scenic Continental Divide Trail and 35 miles of the classic Colorado Trail. This course is wild, tough, and relentless, but with each aid station captained by a 100-mile race veteran, we'll give you the push you need to succeed.
