About this race

The Napa Half Marathon begins at Conn Creek Winery and proceeds along the Silverado Trail toward Napa, with vineyards and wineries bordering much of the path. This race is part of the Napa Valley Marathon weekend in March, which also features a full marathon and a 5K. Both the half and full marathons offer fast, net-downhill courses, attracting both new marathoners and those aiming for personal bests. The full marathon follows a point-to-point course from Calistoga to Napa and is a Boston qualifier, with its route recognized among the Top 50 Boston qualifying courses. The half marathon is recommended by Runner’s World, and Race Raves identified the event as a “Best Bet for Boston Marathon Qualifying Race.” Marathon and half marathon finishers are given a BOCO Gear backpack, medal, and T-shirt. The 5K, organized by the Kiwanis Club of Greater Napa, runs out and back from the finish area, with its proceeds supporting the Napa Valley community.
