High Lonesome 100

The High Lonesome 100 is a high flying endurance race in the Sawatch range of the Colorado Rocky Mountains. With almost 22,000 feet of vertical gain and 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 single track in the state, and takes runners on the Continental Divide and Colorado Trail, through 2 ghost towns, over 5 alpine passes, through remote basins, and over soaring ridges. It's also run and staffed by experienced and quality individuals, so you'll get to be a part of a wonderful community. If you're looking for a true mountain race, created in the spirit of the classic 100 milers, then look no further.
