This week we launched a sale featuring Trek Travel’s California Wine Country tour, a five-night cycling itinerary that stops at some of Napa and Sonoma’s best wineries. We spoke with Jonathan Hershberger, a guide for Trek Travel, and asked all the important questions: How much can you really drink while biking? Do people ever fall down? And do you feel silly at a wine tasting in bike shorts? We also covered some less important ground, like the biggest challenges on the trip, the coolest stop and why their bikes have been in the Tour de France.
