Adrenaline Night Runs

Adrenaline Night Runs - McDowell Mountain Regional Park

Adrenaline Night Runs take place on May 23, 2026 at McDowell Mountain Regional Park in Fountain Hills / Fort McDowell, Arizona. The event is part of the 2026 Insomniac Night Trail Run Series and offers multiple overnight trail distances:

• 50K
• 25K
• 15K
• 10K
• 6K

Courses use rolling desert singletrack with both fast smooth sections and more mountainous, technical sections. Runners follow segments of the Escondido and Cinch trails and the Scenic Ridge trail. The course design features long and short loops that join and return along the Shallmo Trail.

Aid station support includes a fully stocked start and finish area and a remote Escondido aid station on the long loop; Pemberton serves as a water only station. The event is a cupless race, so participants are expected to use a reusable cup or obtain one on site. Drop bags are available at the start and finish area.

Crews are allowed at the start and finish. Pacers are allowed only for 50K runners beginning with the fourth loop. The 50K has an overall time limit and loop-specific cutoffs. Evening weather typically begins warm, with temperatures often in the 90s and cooling as the night progresses. Park entry now carries a fee per vehicle.

Additional event services include chip timing, finish line photos, finisher awards, live split tracking, and volunteer opportunities that offer race credit and race swag. Visit the organization's website for the most recent information.
