About This Race

The 15K serves as an ideal introduction to longer night trail running, offering enough distance to experience the unique challenges of headlamp navigation while remaining manageable for most trail runners. This middle-distance option allows participants to settle into the rhythm of night running without the intimidation factor of ultra distances. Well-suited for runners comfortable with trail running who want to explore the different sensory experience that darkness brings.

The courses utilize McDowell Mountain Regional Park's trail network, featuring classic Sonoran Desert terrain with singletrack paths winding through saguaro cactus forests, over rolling hills, and across desert washes. The Escondido, Scenic, Cinch, and Shallmo trails combine to create loop configurations for each distance, with the longest efforts requiring multiple loops.

Runners can expect typical desert trail conditions including rocky sections, sandy washes, and moderate elevation changes characteristic of the Sonoran landscape. The nighttime format adds navigation complexity while showcasing the desert's nocturnal character, from wildlife sounds to the interplay of artificial light against natural desert features.
