About This Race
The Noble Canyon 50K & 15K stands as one of Southern California's most enduring mountain trail races, having carved its reputation over nearly two decades in the rugged terrain of east San Diego County. Set within the Cleveland National Forest, this USATF-sanctioned event challenges runners with the historic Noble Canyon Trail system, where granite-studded slopes and technical singletrack demand both fitness and focus. The 50K presents a true mountain ultra experience, with significant elevation gain through varied ecosystems from pine forests to exposed ridgelines. Runners navigate rocky climbs, canyon switchbacks, and fast descents while taking in sweeping views of the Laguna Mountains. The course's technical nature and elevation changes create a challenging test that rewards preparation and mountain running experience. The 15K offers newer trail runners or those seeking a shorter mountain challenge a taste of the same rugged terrain. Both distances showcase the natural beauty of this protected landscape while providing the technical trail experience that has kept runners returning for years. Temperature variations from canyon heat to crisp mountain winds add another layer of complexity to race day strategy.
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.
