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. 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. We hope you will join us in 2024 for our seventh year!
