Ouray 50 Mile Endurance Run
August 29th 2026
Ouray, CO
50 Miles
With over over 20k feet gain for the 50-mile, this will be one of the most difficult things you ever attempt. Lucky for you, Ouray (dubbed the "Switzerland of America") is also one of the most beautiful places in the world. Situated in the rugged and stunning San Juan Mountain range in southwest Colorado, your senses will be just as overwhelmed with the views as your quads and lungs are with the relentless climbs. When you top out at the Bridge of Heaven after the final 5,000 foot climb, you will know it is all downhill to Fellin Park where your big belt buckle and the Ouray Hot Springs await.
