The Napa Lapa Trail Adventure

The Napa Lapa Trail Adventure, hosted by Inside Trail Racing, is a unique time-based trail running event held at Skyline Wilderness Park in Napa, California. Instead of racing a fixed distance, participants run as far as possible within 3, 6, or 12-hour time limits on a challenging 4.16-mile loop featuring approximately 815 feet of elevation gain. The course includes fire roads, singletrack trails, and rolling hills, offering a mix of technical and smooth terrain.

Runners can complete multiple laps with breaks in between. The event emphasizes endurance and community spirit, with awards for overall winners, fastest laps, and best-dressed runners. Aid stations provide a variety of nutrition, and the race promotes environmental responsibility by being a cupless event. Visit the organization's website for the most recent information.
