The North Fork 50 Mile/50K is a gem of an ultramarathon in the Colorado mountains just southwest of Denver. The course is 100% soft surface, made up almost entirely of incredible singletrack trails with a few short sections of double track road. 

Climb through open burn areas from a 1996 fire, then dive back into the beautiful ponderosa pines and wind around towering granite rock formations as you excite your senses and challenge your mettle. 

A portion of race proceeds goes to the North Fork Volunteer Fire Department, which supports and serves the local community.
