Come join us on the Rainbow Trail in the Sangre de Cristo Mountains for one of the most breathtakingly gorgeous trail and ultramarathon running adventures in the nation. Run beneath the watchful eye of the jagged and ominous peaks from the confines of the rolling Rainbow Trail. This race is full of festivities, friends, challenge, and fun. 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, traveling together, discovering the hidden treasures in the mountains and those within yourself.

All eight (8) hours must be completed while either performing trail construction or maintenance, or as a race volunteer at any official ultramarathon.

Volunteer Service Requirement Form (<Click Here to Download Form)

Select HPRS events allow a mid-race drop down in distance, where you will still receive a finisher's award and have your finish time in the results, in the event that you bit off more than you can chew.

Any runner who starts the 27k may drop down at the 8-Mile point of their run and receive a finisher's award, as well as their time in the 8-Mile results.

Any runner who starts the 50-Mile may drop down to the 50km by turning around at Macey Creek (not going to Horn Creek Aid). By turning around prior to Horn Creek and returning to Music Meadows you will receive a finisher's award, as well as their time in the 50km results. 

Any runners who starts the 100km may drop down to the 50-mile by skipping their final ascent of Music Pass. Runner's who do not do the final Music Pass out and back will receive a finisher's award, as well as their time in the 50-Mile results.

Any runner who starts the 100-Mile may drop down to the 100k by not doing their 2nd out-and-back to Venable (but must still do a final Music Pass), and receive a finisher's award, as well as their time in the 100k results.

Any runner who starts the 200-Mile may drop down at the 100-Mile mark and receive a finisher's award, as well as their time in the 100-Mile results.

There is no drop down option for the 8-Mile or 50km distances; meaning, you must finish the distance you start if starting one of those distances.

There are no refunds or credits, full or partial, for the difference in distance dropped to. HPRS supports responsible risk management decisions of our runners to call it a day if the challenge is more than you're feeling up to. Live to run another day!

Event check-in will take place at the Start/Finish area on private land before Grape Creek Trailhead on County Road 119, Westcliffe, CO 81252

Times:
Tuesday 6:00 PM - 8:00 PM
Friday 4:00 PM - 8:00 PM
Saturday 3:00 AM - 6:00 AM 
Sunday 7:30 AM - 9:00 AM

Held virtually on Sunday, September 22nd at 7pm Mountain Time.

A NOTE ON CREWS/SPECTATORS:
50-mile and 100km Runners: Due to access difficulty in the area, crew and spectator access will be available at the start/finish area ONLY (aka Music Meadows Aid Station). Crews can attend to their runners twice for the 50 Mile and 100k at THIS STATION ONLY.
 
The Start/Finish area (Music Meadows Aid Station) is located adjacent to the Grape Creek Trailhead on Custer County Road 119 30-min south of Westcliffe, CO.
 
100-mile Runners: The 100-mile distance will be limited to 50 total runners. Each runner will be allowed one (1) crew vehicle that may access the Horn Creek and Venable Aid Stations for crewing purposes. You will be provided with one (1) vehicle placard at check-in, which must be displayed on this vehicle at all times at these locales.
 
In the event that more than 25 runners are using a crew for the race, we will split the field of 100-mile crews into two "buckets." These buckets will be known as "Crew Lot 1" and "Crew Lot 2." Half of the crews (min 13 | max 25) will be in Crew Lot 1, and the other half (min 13 | max 25) in Crew Lot 2.
 
Crew Lot 1: Crews assigned to Crew Lot 1 will be able to access runners at Horn Creek Aid Station ONLY during your first out-and-back; and Venable Aid Station ONLY during your second out-and-back.
 
Crew Lot 2: Crews assigned to Crew Lot 2 will be able to access runners at Venable Aid Station ONLY during your first out-and-back; and Horn Creek Aid Station ONLY during your second out-and-back.
 
We will only split crews in half, provided more than 25 runners are present on race day with a crew. If fewer than 25 runners are present with a crew, those with a crew will be able to access both Horn Creek and Venable Aid Stations as you desire on both out-and-backs. Should we start with more than 25 crews but later drop to fewer than 25 crews, we will end the crew split, and crews will be able to access both Horn Creek and Venable Aid Stations as you desire them to from that point forward.
 
Crews may tend to runners at Music Meadows (Start/Finish Aid Station) each and every time 100-milers pass through without additional regulation.
 
For further restrictions related to parking, timing, and other crew regulations: Please refer to the Crew and Pacer Manual in the runner's drive (Coming Soon!) for more info.

Why? The road to Colony Creek is incredibly rough and very rocky, and a high clearance 4x4 vehicle is required for access, with no parking options for crews or spectators. The trailheads where Horn Creek and Venable aid stations are located are incredibly small trailheads, and it is a condition of our permit that we afford access to other trail users during our event. Simply put, there is nowhere for you to park anywhere else along the course, and our permit prohibits crews and spectators elsewhere. This is non-negotiable.

PACERS: Runners in the 100-Mile, 100k, and 50-Mile may all pick up a pacer at Music Meadows. 100-Mile and 100k runners may pick up a pacer on their final time through Venable and Horn Creek Aid Stations, and at these locales ONLY, pacers must arrange their own ride, and be dropped off at the aid location. This is a "drop and leave" situation, where crews and spectators are NOT allowed and pacers may only be dropped off to wait for their runner. More information about this policy will be available closer to race day.

For further restrictions related to parking, timing, and other crew regulations: Please refer to the Crew and Pacer Manual in the runner's drive (Coming Soon!) for more info.

Please see our aid station chart sheet for the exact mileage/locations where you can pick up a pacer. All pacers must sign a waiver, receive a pacer bib, and are required to carry a headlamp. Pacers are not allowed for the 50k, 27k, or 8-Mile.

All participants are allowed to have a drop bag at Music Meadows, as well as Horn Creek and Venable for those who are going there. Drop bags should be dropped off on race morning prior to the start of your event.  All participants may have access to their drop bag every time they are at Music Meadows. You are also allowed access to your car or tent. Please leave nothing of value in your bag. Do not leave your drop bag behind. All abandoned drop bags are disposed of immediately at the conclusion of the event. 

All participants and spectators will park on-site at the start/finish area. A map of this areas will be available closer to the race. 

All participants who complete their challenge will receive a unique finisher's award. All official 150-Mile and 100-Mile Finishers will receive a Sangre de Cristo Endurance Run belt buckle highlighting their distance. We'll also present our DFL and Transcendence Awards. HPRS does not have a podium or age group awards, please see our Awards Page for more details.

NO AWARDS WILL BE MAILED

This event is being held in accordance with permits from the U.S. Forest Service, San Isabel National Forest – San Carlos Ranger District, and two private land owners. We ask that you please respect and care for the land this event is held on to help ensure the future of this race and to limit our environmental impact.

Want to earn a Sangre de Cristo 200-mile finisher's buckle?

After the 2024 running of the Sangre de Cristo 200-mile, we terminated the distance due to a lack of interest. We still have several Sangre de Cristo 200-mile finisher buckles left over.

If you want to earn your own Sangre de Cristo 200-mile finisher's buckle, here's how:

1.) You must run 100-Miles between 4:00am MT on Wednesday, September 24, 2025 and 4:00am MT on Saturday, September 27, 2025.

• This 100-miles must be run within the window provided above.
• This 100-miles must be run anywhere in the Sangre de Cristo Mountains. Where and how is up to you. We suggest a point-to-point running of the Rainbow Trail from its beginning near Poncha Springs on US-285. From this point, our event site is 99.12 Miles (+/-) away, with 19,612' of Climb and 19,885' of Descent along the route. While we suggest this route, again... the route you decide is ultimately up to you.
• This first 100-mile adventure should be supported by your crew and/or pacers in whatever manner you see fit. The only requirement is to run 100 miles on foot following all normal race rules and regulations (no pacing via vehicle or bike). 
• You must provide HPRS with a gpx track of your first 100 miles before the official Sangre de Cristo 100-mile ends on Sunday. 

2.) After completing your first 100 miles within the aforementioned window, you must then complete the official Sangre de Cristo 100-mile within its official cut-off of 38 hours.

3.) Only those who register for and finish the official Sangre de Cristo 100-mile race in addition to their self-supported 100-mile adventure in the days prior will be provided with a 200-mile Finisher's buckle.
• You will only receive one (1) Finisher's Buckle, not the 100-Mile and 200-Mile Finisher Buckles.
• Those who fail to complete the self-supported 100 miles before the official Sangre de Cristo 100-mile but then go on to finish the official Sangre de Cristo 100-mile event will receive a Sangre de Cristo 100-mile finisher's buckle.

The term "Self-supported" within the narrative above refers to you figuring out your own support system. It refers to HPRS not being responsible for you or to you. You run the first 100 miles at your own risk and utilizing your own judgment. 

Any additional event information, changes, and updates will be sent to registered entrants ONLY via e-mail communication.
