The Napa Lapa Trail Adventure

The Napa Lapa Trail Adventure

The Napa Lapa Trail Adventure is a time-based trail run hosted by Inside Trail Racing at Skyline Wilderness Park in Napa, California. Instead of a fixed distance, participants run as far as they can within a set time period. Events offered include multiple time formats and relay options.

Race options:

• 12 Hour
• 12 Hour Relay (teams of 2 or 3)
• 6 Hour
• 6 Hour Relay (teams of 2)
• 3 Hour

The course uses a main loop of just over 4.1 miles and a short loop of 0.34 miles that opens for the last 40 minutes of each event. Each full main loop has approximately 815 feet of elevation gain. Relays use a single bib that teams pass between runners; teams may choose their own exchange strategy.

Aid stations provide a variety of foods and beverages such as Skratch Hydration Mix, Spring Energy products, trail mix, PB&J, bananas, and other typical aid station items. Runners are encouraged to carry at least one 20 oz bottle during their run. Alcohol is allowed in the park but participants are not permitted to drink while their event is in progress; anyone who drinks during their event will be finished.

Awards include top three overall winners for each distance, fastest lap awards, best dressed, age-group medals in listed categories, finisher medals, special items for 12 Hour entrants, and a Dead Last Finisher award. Race shirts are performance tri-blend tees; to guarantee a shirt and size, registration must be completed by July 25, 2026.
