Prepare for an exhilarating high-altitude challenge at the Pajarito Mountain Run, set for August 22, 2026, in scenic Los Alamos, NM. This demanding 10K trail race kicks off at the 9,000-foot base of the Pajarito Mountain Ski Area, immediately immersing runners in a journey through its extensive trail network. The course features a significant ascent of 1,400 feet over approximately 2.4 to 3.25 miles, taking participants to the Pajarito Mountain summit at an impressive 10,442 feet. The climb begins with a mile of rolling singletrack before transitioning to a service road for the main ascent, culminating in breathtaking panoramic views of the Rio Grande Valley and surrounding landscapes.

After conquering the summit, runners will experience a serpentine descent primarily along the "Aspen For Trouble" Trail, a mix of singletrack and brief service road sections that lead back to the Lodge. This grassroots event is renowned for showcasing challenging high-alpine New Mexico trails, offering a refreshing escape from the summer heat, with typical race day conditions seeing highs around 80°F and lows around 55°F, and only a 12% chance of precipitation. A summit aid station, approximately three miles into the race, provides water and some sports nutrition gels, with a strong encouragement for runners to carry their own hydration vessels.

The Pajarito Mountain Run is more than just a race; it's an opportunity to connect with nature and contribute to trail preservation. A portion of the entry fee supports local trail maintenance through the Enchanted Circle Trails Association, underscoring the event's commitment to trail stewardship. The start and finish lines are conveniently located near the Lodge at Pajarito Mountain Ski Area, promising a memorable and challenging experience for all participants amidst stunning mountain vistas.
