About This Race
The 50K distance represents the marquee challenge of the evening, demanding both physical endurance and mental fortitude as runners navigate technical Pacific Northwest terrain in complete darkness. This ultra pushes participants through sustained periods of solitude where headlamp beams become the primary connection to the trail ahead. The distance requires careful pacing and navigation skills, making it ideal for experienced trail runners ready to test themselves in night conditions.
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.
