The event is a ticket into the heart of the world-famous wine regions of the Napa and Sonoma valleys, and once you're there, you won't want to leave. There are B&Bs and boutique hotel options to suit every budget, as well as thousands of wineries, craft breweries, and farm-to-table restaurants for pre-race fueling and post-race celebrations. The race also offers a springboard for vacation itineraries including the San Francisco Bay Area, Santa Cruz mountains, and coastal redwood forests.
