Ouray 100 Mile Endurance Run
July 17th 2026
Ouray, CO
100 Miles
With over 40k feet of gain for the 100 miler, 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.
