Make no mistake, the elevation profile for The Sheep Mountain 50 mile and 50k are docile looking. However, the average elevation of over 10,500’ and copious amounts of aggressive terrain, will see you waddle away from this race in shock. Come ready my friends, this mountain throws everything it has at runners, challenging you from start to finish. We 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. (It’s more of a love-hate relationship, really).The third series of races we host in Fairplay, The Sheep Mountain 50 mile and 50k promise to provide runners with an unforgettable experience that celebrates the history, and rough and tumble nature of this mountain region.
