Napa Wilderness Trail Runs
Napa Wilderness Trail Runs takes place at Skyline Wilderness Park in Napa, California and is organized by Bay Trailrunners. The event offers multiple trail distances, marked courses, staffed aid stations, and on-site parking and camping managed through the park.
Distances
- 50K: 32.4 miles, ~6,700 ft elevation gain, 10 hour cutoff
- 30K: 18.2 miles, ~4,000 ft elevation gain, 8 hour cutoff
- 21K: 13.9 miles, ~2,600 ft elevation gain, 6 hour cutoff

Course notes highlight new trail sections through Napa Open Space and include the Rim Rock Trail climbs, which provide broad valley views from the summit. Course maps and elevation profiles are finalized shortly before the event and runners are advised to review published routes in advance.
Logistics and on-course support include a $6 parking fee covered by registration, required South Gate overflow entry for runners, bib pickup that opens one hour before each race, and a mandatory race briefing ten minutes before each start. Aid stations appear approximately every 5 to 9 miles with Skratch, Cure Hydration, and GU products and plant based options; volunteers will pour fluids into containers. There is a roughly 7 mile stretch served only by a water stop, so longer distance runners must carry sufficient supplies.
Additional details: the event is cupless so runners must bring their own cup or bottle, there are no restrooms on course, finishers receive an insulated Bay Trailrunners cup, and final results are posted on UltraSignup within 72 hours.
