“Wilderness is not a luxury, but a necessity of the human spirit.”
– Edward Abbey

Come join us on the Rainbow Trail in the Sangre de Cristo mountains. Run beneath the watchful eye of these gorgeous, and ominous, mountains. You may even think to yourself, ‘what a wonderful world’. This race is full of festivities, friends, challenge, and joy. Camp out with the HPRS tribe, whichever distance you choose you’ll wander through the Southern Colorado Rocky Mountains, and embrace the feeling of the wilderness within, while you run along the literal wilderness boundary the entire way. No race in our country is in a more wild setting. This unique race is about community, it is about traveling together, it is about discovering the hidden treasures in the mountains and those within yourself.

Join the original creator of the first ever 200-miler in the world, our race director, Sherpa John for 200 amazing miles in the SdC!

CAMPOUT! The land our start/finish line is hosted on is private ranch land where we are priviledged guests. We have been afforded the opportunity of TENT CAMPING ONLY for a nominal fee per site. This in order to help minimize and mitigate our impact on the resource the ranch owner relies on for their herd of cattle, and allows us to give back to those who’ve allowed us use of their beautiful land. We encourage you to be a part of this amazing tribe, and immerse yourself, on this weekend. The camping fee is $10 per site/family for those in the 50k, 50-Mile, and 100k. The $10 site fee has been built into the entry fee for the 100-Miler. Please email the race director about camper vans, rooftop tents, or other options. You can purchase your site during registration as an add-on, or later on by CLICKING HERE

Course: The course is an out-and-back that begins and ends on Private Ranch Land off of Custer County Road 119 located south of Westcliffe, CO. Runners will negotiate the Rainbow Trail, and Music Pass Road/Trail, within the San Isabel National Forest/San Carlos Ranger District. Runners will negotiate these trails and roads at elevations between 9,000 and 11,400′. On this section of the Rainbow Trail, the trail is just wide enough for ATVs to travel on. It is not a double track trail or road, not quite single track. The trail is rugged and remote and serves as the boundary of the Wilderness Area along it’s entire western flank.

Each aid station will be fully stocked with water, electrolyte drink, and assorted “Ultra” snacks. Aid station cut-offs have been set against the slowest possible pace possible to successfully finish the event. Therefore, the cut-offs in this event are strict. Please see our Aid Stations chart for more details.
