The Above the Clouds Ultra begins and ends on the track at Merit Academy in Woodland Park, Colorado, a mountain town known as the City Above the Clouds. This yearly trail event features a 50k and a 10k. The 50k gains 4,137 feet, and the 10k gains 1,126 feet. It is a mountain trail race, not a road ultra, featuring climbing, singletrack, forest roads, and long sections through National Forest land. The 50k route ascends Lovell Gulch to Rampart Range Road, proceeds south with clear views of Pikes Peak, and then encircles Rampart Reservoir on quick singletrack. It then links to the less-trafficked 700.A National Forest trail, moves north on quiet forest roads, and finishes by descending the latter half of the Lovell Gulch loop. Aid stations are located at Lovell Gulch, Rainbow, Dam, and Rampart Ridge. Offerings include Tailwind, Muir Energy gels, fruit, snacks, and hot items like bacon, quesadillas, and potatoes. Crews may meet 50k runners at certain aid stations, but Rampart Ridge is closed to crews, and reaching the Dam aid station requires passing a paid entry point.

Run Denver 'Mile High City' 5K/10K/13.1 is a local Denver running event offering 5K, 10K, and half marathon distances, taking place in late November. It functions more like a supported group run than a large race: each wave is limited to approximately 15 to 20 participants, both runners and walkers are accepted, and timing chips are not used. The atmosphere is intentionally relaxed. Bibs are distributed on race day, participant gifts are mailed out, and organizers can record times by bib number upon request. Waves begin in the morning and are filled sequentially, with a waitlist or virtual run offered once capacity is reached. Participants receive a shirt, medal, and entry into a virtual runner community; the virtual option also includes text-based coaching support prior to the run.

The Thanksgiving Gobble Trot Run 5K/10K/13.1 is a Denver/Aurora holiday race series offering 5K, 10K, and half marathon distances. Organized by The Best Races, it centers on a Thanksgiving morning running tradition: participants can race, jog, or walk before the day shifts to stuffing and turkey. The event welcomes families, friends, and local runners, not exclusively competitive athletes. The core idea is to enjoy the outdoors with others, complete a manageable distance, and burn calories before the Thanksgiving meal.
