Take a ride into the heart of the world-famous wine regions of the Napa and Sonoma valleys.
The bike course is 56-mile long and features gentle rollers and one tough climb, that winds through vineyards and quaint towns. It is a technical demanding ride with many rolling hills and curves. It has just under 2000 feet of climbing, including a 385 foot climb on Chalk Hill. But most of all the course is extremely beautiful, passing endless miles of vineyards and dozens of wineries.
