This scenic and fast 13.1 mile course starts at Cuvaison Carneros Winery where runners congregate in one of the most beautiful start areas anywhere. You’ll warm up next to the winery alongside rows of rolling vineyards and a reservoir. Runners must be dropped at the entrance to the winery by bus or by vehicle in the Domaine Carneros parking lot. There is NO parking there or anywhere near the start area!

Out of the starting gate, you’ll take a left turn on Duhig Rd. and make your ascent up Butt Burner Hill. Once over the crest it’s a beautiful cruise downhill into the Carneros wine appellation. Enjoy vistas of the Napa-Sonoma Marshes Wildlife Preserve, San Pablo Bay and Mt. Tamalpais in Marin as you wind through hundreds of rolling acres of vineyards and wineries. The course also passes ranches and farms filled with a variety of animals including horses, cows, pigs, sheep, goats, llamas, chickens and donkeys.
