The Napa Lapa Trail Adventure

The Napa Lapa Trail Adventure is a time-based trail run event. Participants run as far as possible within a pre-determined time limit instead of a set distance. The event offers three time categories: 12 Hour, 6 Hour, and 3 Hour events.

The race takes place at Skyline Wilderness Park in Napa, California. The park features 25 miles of multi-use fire roads and singletrack trails. The main course is a loop measuring 4.16 miles with approximately 815 feet of elevation gain per loop. The majority of the course uses fire trails and moderately technical dirt trails, including single track, smooth hills, and descents. During the final 40 minutes of each timed event, a shorter 0.34-mile loop opens for runners to continue.

A full aid station is located at the Start/Finish, and a water-only station is at mile 2. The event is cupless, so runners must carry their own water bottle or reusable cup. Aid stations provide items like Gu Energy products, trail mix, pretzels, fresh fruit, soda, and Skratch Labs hydration mix.

The event has a capacity of 500 runners across all distances. Bibs are professionally chip-timed. Awards include overall winner trophies, finisher medals, and age-group medals. A special pint glass is given to all 6 Hour finishers. Visit the organization's website for the most recent information.
