Napa Wilderness Trail Runs

Napa Wilderness Trail Runs, held at Skyline Wilderness Park (2201 Imola Ave, Napa, CA), offers a spectrum of trail races from a 10K up to a 50K. The event emphasizes accessibility for all levels, with a 50K and 30K designed with guidance from ultra runner Angela Abbey. The courses feature Rim Rock Trail with steep climbs and panoramic Napa Valley views, with summit vistas toward Mount Diablo, Mount Tamalpais, and Mount Saint Helena.

Aid stations are cupless and spaced roughly every 5–9 miles; plant-based nutrition is provided. Runners and volunteers receive Bay Trailrunners gear, and post-race wraps are available; dogs allowed at start/finish and camping areas. Visit the organization's website for the most recent information.
