About This Event

The McDowell Mountain Trail Run offers a challenging 15-mile journey through Arizona’s McDowell Mountain Regional Park, showcasing some of the Southwest’s most distinctive desert terrain. The course winds through cholla forests and beaver tail cactus fields, combining steady climbs with rewarding descents across the park’s extensive trail network.

Runners follow a scenic route from Cinch to Scenic Trail, then over to Pemberton before threading through Tonto Trail. The finale delivers a fast, flowing descent down Shallmo Wash that rewards the earlier climbing efforts. The terrain mixes technical rocky sections with smoother cruising segments, demanding both fitness and trail running skills as you navigate the desert landscape.

As part of the XTERRA Trail Run World Series, this race attracts a mix of local desert runners and visiting athletes seeking to qualify for the XTERRA World Championships. The event awards 28 XTERRA Trail Run World Series passes, making it particularly appealing for competitive runners eyeing international competition. Awards recognize the top three finishers in each age group.

The noon course closure keeps the pace honest without being overly restrictive for most trail runners. McDowell Mountain Regional Park’s high desert setting provides dramatic mountain backdrops and unique Sonoran Desert flora that sets this race apart from typical trail running venues. The well-maintained trail system and reliable desert weather create ideal conditions for both racing and post-run exploration of the park’s extensive trail network.
