About This Race
The 50K presents an ideal stepping stone for runners ready to progress beyond marathon distance while experiencing the full character of the San Bernardino Mountains without the multi-day commitment of the longer ultramarathons. This distance allows runners to tackle the technical climbs and diverse terrain changes at a more manageable pace, making it particularly suited for first-time ultra runners or those seeking a challenging mountain race that can be completed in a single push through the day. The course provides enough distance to experience the full range of climate zones and technical challenges that define Kodiak, while maintaining cutoff times that accommodate runners building toward longer UTMB World Series goals.
