The Course

COOL START AREA AT CUVAISON!
A new start area was introduced in 2006 to accomodate a larger field! This scenic Napa to Sonoma 13.1 mile course now starts at Cuvaison Carneros Estate on Duhig Road just off of Hwy 121. 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. Once out of the starting gate, there is a short but steep acsent up Duhig (Butt Burner Hill) and then it’s a beautiful cruise down into the Carneros wine country.

Enjoy vistas of the Napa-Sonoma Marshes Wildlife Area, San Pablo Bay and Mt. Tamalpais in Marin, as you wind through hundreds of rolling acres of vineyards and wineries. You'll also pass ranches filled with a variety of animals including horses, cows, pigs, sheep, goats, llama’s, chickens and donkeys on your way into Sonoma.

IMPORTANT! Race participants must obey CHP, police and course marshals at all times! There are two key intersections where extra precaution must be taken. At the 7.5 mile mark you will cross Hwy 121, a major connector between the Sonoma and Napa Valleys which experiences regular traffic. And at the 10 mile mark you will cross Napa Rd. Please group as much as possible to allow cars to get through and take extra caution as you approach any intersections where cars are stopped. Runners and racewalkers must be prepared to stop if deemed necessary by the CHP. Thanks to the support of our neighbors and local government agencies, we’ve been allowed access to this fabulous course. Please respect that privilege. Thanks and enjoy!
