About This Race

The 50K at Noble Canyon demands endurance and technical skill as runners navigate over three times the distance of the 15K option, requiring careful pacing through the same challenging terrain that includes rocky singletrack, steep climbs, and desert washes. This distance suits experienced trail runners ready to test their limits on San Diego's rugged backcountry, where the extended time on technical footing becomes as much a mental challenge as a physical one. Runners will need to master nutrition and hydration strategies while maintaining focus through multiple hours of demanding desert trail running.

Both races follow an out-and-back format through the Noble Canyon Trail system, starting and finishing at Pine Creek Road in Pine Valley. The course features technical singletrack trail with rocky climbs, exposed ridgelines, and fast descents through varied terrain including pine forests, open granite slopes, and canyon switchbacks. Runners experience significant elevation changes with sweeping views of the Laguna Mountains throughout the journey.
