The Experience
The Napa Valley Trail Half Marathon, organized by Enviro Sports, takes runners through the scenic trails of Napa Valley wine country. Starting in Calistoga, the course winds through rolling vineyards and oak woodlands, offering a peaceful escape into nature. Typical race-day weather is mild, with temperatures ranging from 44 to 64°F, making for comfortable running conditions.
With a median field of just 71 runners from about 8 states, the race maintains an intimate, low-key atmosphere. First held in 2016, the event now boasts its 8th edition, drawing trail enthusiasts seeking a quiet weekend in wine country. The finish area offers post-race refreshments, and the surrounding valley is prime for exploration.
