About This Race
The HOKA Kodiak Ultras by UTMB 50K sits at the threshold where trail running becomes true mountain ultrarunning. Set in the San Bernardino Mountains at Big Bear Lake, this race offers 30 miles through high-altitude terrain that shifts between pine forest and exposed ridgeline. As part of the UTMB World Series, it draws runners seeking qualifying points alongside those simply ready to test themselves beyond marathon distance. The October date provides a window of favorable mountain conditions, with summer heat behind and winter storms still weeks away. Big Bear Lake sits at 6,750 feet, meaning runners start and finish at elevation that demands respect in pacing strategy. The course's technical sections require attention to foot placement, while the overall distance allows for recovery from mistakes that might end a longer race. This distance serves runners moving up from marathons without requiring the overnight gear and multi-day recovery of 100K or 100-mile events. It's long enough to demand proper fueling strategy and mental toughness when fatigue sets in, but short enough that most runners will finish in daylight and sleep in their own beds that night.
The course traverses the San Bernardino Mountains through terrain that ranges from maintained forest trail to exposed alpine sections. Runners encounter the full spectrum of high-altitude mountain challenges: rooted forest singletrack, rocky ridgeline, and the thin air that makes every climb more demanding. The route's mixed terrain requires variable pacing, with technical sections slowing progress and smoother fire roads offering chances to open up the stride.
