From the Organizer
Come ready my friends, this mountain throws everything it has at trail and ultra runners alike, challenging you from start to finish at an average elevation over 10,600′. You’ll run amongst these “beautifully difficult” mountains and hills lining the western slope of the South Park Valley. This is the race where you carry #Adversity on your back, if you can handle the burden, you can win the day! Runners looking for a wilderness experience, stunning views, opportunities for technical terrain mixed with remote forest service roads… will fall in love with this course. The Sheep Mountain 50 mile and 50k promises to provide runners with an unforgettable experience that celebrates the history, and rough and tumble nature of this mountain region. The Sheep Mountain Half Marathon is a wonderful introduction into trail running for those looking for a more mellow day. The course features flowing dirt county roads and USFS Fire Road (some of a little rocky).
