Prepare for an unparalleled mountain ultra adventure at the Sangre de Cristo Trail Festival on September 26, 2026, in Westcliffe, CO. Offering 100M, 100K, 50M, and 50K distances, this event plunges runners into the heart of the San Isabel National Forest, with courses primarily traversing the rugged and remote Rainbow Trail and Hermit Pass Road. You'll navigate elevations ranging from 9,000 to a breathtaking 13,500 feet, featuring long, steady climbs and descents that are both challenging and runnable. Expect stunning, expansive views of the Sangre de Cristo Mountains, with the potential for vibrant autumn leaves and even an early season dusting of snow as typical race day conditions often see highs around 69F and lows near 35F, with minimal chance of precipitation.

The Sangre de Cristo Trail Festival, hosted by the Human Potential Running Series, begins and ends at the scenic Music Meadows Ranch, adjacent to the Grape Creek Trailhead. This out-and-back course is renowned for its wild setting, tracing the literal wilderness boundary and providing a deep sense of community and camaraderie. Runners describe the terrain as ATV-width trail, not quite single track, with notoriously rocky and technical access trails to certain aid stations, particularly Horn Creek and Venable. Well-stocked aid stations, offering water, electrolyte drinks, and ultra-specific snacks, are strategically placed along the route, with varying numbers of stops based on distance. Drop bags are also available at key locations, including the start/finish and designated remote aid stations for longer distances.

This festival is more than just a race; it's an immersive experience designed for discovery both in the mountains and within oneself. While the demanding altitude and challenging terrain ensure strict cut-offs, the atmosphere is supportive, celebrating festivities, friendship, and the joy of embracing the wilderness. Runners can even opt for on-site camping at the start/finish, fostering a unique "HPRS tribe" feel.
