Prepare for an unforgettable night on the trails with the Moonlight on Mt Ascension Trail Run, a unique 12-hour challenge set for June 19, 2026, in Helena, Montana. This event, organized by the Helena Ultra Runners League (HURL), stands out as the only one of its kind in Montana, offering runners the chance to conquer the rugged South Hills trails under the glow of the moon. Participants will tackle a modified figure-8 loop course, entirely composed of singletrack through the Mount Ascension and Rodney Ridge areas. Each demanding loop spans 11.57 miles and features an impressive 2,645 feet of elevation gain, characterized by plenty of rocks and uneven terrain. As you navigate the night, keep an eye out for potential wildlife, including deer, black bear, and mountain lions.

The race begins at 8:00 p.m. on Friday, running until 8:00 a.m. on Saturday, allowing runners 12 hours to complete as many full loops as possible. This isn't a continuous effort; runners are encouraged to manage their race strategically, taking breaks or even napping between loops before returning to the course. The event offers a comprehensive aid station at the Old Shooting Range Trailhead, stocked with essentials like typical aid station food, HEED, Perpetuem, Hammer Gel, water, plus warm soup, coffee, and hot chocolate to fuel your nocturnal adventure. Course markings will be clear with ribbons, signs, reflective tape, and glow sticks guiding the way.

Typical race day conditions in June see comfortable highs around 77°F and lows around 50°F, with only an 8% chance of precipitation, providing ideal conditions for a night on the trails. Beyond the challenge, runners have praised the Moonlight on Mt Ascension for its organized, low-key atmosphere and stunning views of Helena at night. With a limited entry field of just 75 runners, securing your spot in this distinctive ultra-experience is highly recommended. Afterward, celebrate your accomplishment with fellow runners over pancakes and bacon at the awards ceremony.
