Über Ouray 100 Endurance Run

"Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure... than to rank with those poor spirits who neither enjoy nor suffer much, because they live in a gray twilight that knows not victory nor defeat." -Theodore Roosevelt.

With over 40k feet of gain for the 100 miler (and over 20k feet gain for the 50), 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.



The top male and female 100 mile finishers will each receive $1,000. The top male and female 50 mile finishers will each receive $500. The payment of these cash awards will be subject to the results of urine and/or blood testing that will be administered to winners immediately after the event by the United States Anti-Doping Agency. Banned substances tested for will include steroids, testosterone, EPO, and THC. (Fear not, Colorado people. Only THC levels above the threshold of 150 ng/ml will trigger a positive result. Doping agencies chose that threshold so that out-of-competition use should not trigger a positive result. In other words, lay off the magic brownies prior to and during the event.)

Maximale Zeit

100 Miles: 52 hours and 50 Miles: 24 hours.
