We are pleased to present one of the most beautiful and challenging trail racing events in the state of Colorado with breathtaking (literally and figuratively) views of Clear Creek County and the Continental Divide. Participants will reach a top altitude over 13,000 feet.

The 50K course climbs over 6500 feet.  Due to the difficulty and remoteness of this race, prior ultra running experience is required.

The 22K course follows the first part of the 50K, making it one of the toughest half-marathons in the state, with 3400′ of climbing, reaching an altitude of 13,200′.  The 22K course is not recommended for novice trail runners.  It is a tough course at high altitude.
