Quad Rock 25 & 50 Mile Trail Races

Prepare for an unforgettable challenge at the Quad Rock 25 & 50 Mile Trail Races, set to take place on May 9, 2026, in the stunning landscapes surrounding Bellvue, CO. This event, crafted by trail runners for trail runners, offers participants a deep dive into the rugged beauty of Lory State Park and Horsetooth Mountain Park. Runners can choose between a demanding 50-mile ultra or a challenging 25-mile single loop, both promising an exceptional early-season test amidst the Colorado Rockies.

The course is renowned for its diverse and demanding terrain, featuring approximately 85% premium singletrack and 15% dirt road. The 25-mile loop alone boasts over 5,500 feet of vertical gain, with the 50-mile race doubling that to more than 11,000 feet as runners tackle the same loop in reverse for the second half, offering a unique change of perspective. Expect a relentless series of "quad-beating" climbs and descents, ranging from 800 to 1500 feet at a time, across runnable sections and technical stretches filled with rocks, roots, and steps. Along the way, runners are treated to expansive views of the Fort Collins skyline, the vast Great Plains to the east, and the majestic Longs Peak dominating the western horizon. Typical race day conditions in early May often bring highs around 67F and lows around 41F, with an 11% chance of precipitation, creating dynamic running conditions.

Beyond the challenging course, the Quad Rock experience is celebrated for its exceptional organization and vibrant atmosphere. Runners consistently praise the "super well organized" race and the enthusiastic, knowledgeable aid station staff and volunteers who provide fully stocked stations, often equipped with ice and dousing sponges for warmer sections. Participants can look forward to a rewarding post-race experience, including a substantial finish line meal with diverse dietary options, a choice of race T-shirt, a finisher award, and complimentary race photos to capture their epic journey. This event is not just a race; it's a testament to the trail running spirit, offering an impeccably marked course and a memorable day in the mountains.
