One of the most prestigious races in Northern California, the Napa To Sonoma Wine Country Half Marathon is 13.1 miles of racing and tasting. The course begins at the opulent Cuvaison Winery in Napa, running alongside miles of vineyards, ranches, wineries and the Napa-Sonoma Marshes Wildlife Area, before entering spectator-lined streets in downtown Sonoma for the final stretch. After the Half Marathon, participants and spectators have the opportunity to enjoy all that wine country has to offer with food, music, and over 25 wineries on hand to distribute tastings.
