About This Race
The half marathon strikes an ideal balance for runners ready to step beyond shorter distances while exploring meaningful trail mileage. This 13.1-mile route provides ample opportunity to settle into trail rhythm and experience the changing character of the canyon environment. The distance appeals to road runners transitioning to trails and experienced trail runners seeking a strong tempo effort.
The courses wind through the canyon and ridge systems characteristic of Northern California's transition zone between valley floor and true mountains. Runners encounter a varied terrain palette of oak woodlands, chaparral-covered slopes, and seasonal creek crossings. The single-track sections demand technical attention, with roots, rocks, and quick elevation changes requiring focused footwork.
The longer distances incorporate significant climbing that rewards runners with expansive views across the surrounding valleys before plunging back into shaded canyon sections. Fire road segments provide opportunities to open up the stride and make time, while the single-track portions keep runners honest with their pacing strategy.
