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 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 cupless. Visit the organization's website for the most recent information.
