About This Race
The HOKA Kodiak Ultras 21K offers runners a focused introduction to the San Bernardino Mountains through terrain that reflects the full character of the UTMB World Series event. Starting and finishing in Big Bear Lake at 6,750 feet elevation, this course delivers a genuine mountain running experience without requiring the extended commitment of ultra distances. The route moves through mixed terrain that includes singletrack trails, forest roads, and technical sections representative of Southern California's high country. Runners encounter the ecological transitions that define this mountain range, from Jeffrey pine forests to exposed ridgeline segments. The half-marathon format allows for purposeful pacing while still demanding respect for altitude and variable trail conditions. As part of the UTMB World Series, the race draws a field that ranges from regional trail runners to international competitors using the distance as preparation for longer mountain objectives. The Big Bear Lake finish area serves as a gathering point for the full Kodiak weekend, creating a festival atmosphere without the manufactured hype common to many destination races.
The 21K course begins in Big Bear Lake village and works through terrain that showcases the San Bernardino Mountains' diversity. Runners navigate singletrack trails, fire roads, and technical sections that require attention to footing and line choice. The route's design emphasizes the natural features of the range rather than manufactured difficulty.
The high-altitude start means runners begin at elevations where oxygen is noticeably thinner, a factor that affects pacing from the opening miles. Course markings follow UTMB standards, and aid stations are positioned according to World Series protocols.
