The Napa Lapa

The Napa Lapa Trail Adventure, held at Skyline Wilderness Park in Napa, California, is Inside Trail Racing’s first time-based ultrarun. Runners compete for a set amount of time rather than a fixed distance, choosing to cover as much terrain as possible within 3, 6, or 12 hours. Each loop is about 4.16 miles with 815 feet of climbing, traversing fire roads and dirt single-track amid Napa hills.

The course is cupless, with aid stations offering gels, snacks, and hydration. The event emphasizes pace, endurance, and fun, with awards like The Lapa Lapper, Grappa Lapper, and Dapper Lapper, plus finish medals. Visit the organization's website for the most recent information.
