Join us for the 34th Annual Napa Valley Trail Marathon, hosted by Enviro-Sports at Bothe-Napa Valley State Park. You can choose from a marathon, half marathon, or 10K, with all events starting and finishing at the park.

This well-organized event features chip timing, aid stations, and post-race refreshments. The course meanders through the park’s trails, offering hills, streams, and rocky sections—making it somewhat challenging, but ultimately rewarding!
