Our group of 8 completed a bike wine tour with SVBT&R, and we had a great time. We had mixed fitness levels and a couple found one leg particularly challenging due to a small hill and strong wind, but it wasn't overly taxing and we survived. Traffic wasn't too bad on the roads we traveled. We visited 3 wineries and traveled a total of 15 miles, both more than enough. The travel itinerary was changed by our guide that day, but we weren't fixated on any particular winery and greatly enjoyed 2 of the 3 tastings. The isolated exception was due to the winery rather than the tour company. Our guide was personable and knowledgeable, and he knew when to talk and when to let us just socialize and hang out. Everything was setup in advance, and all was ready for us when we arrived. All in all, a great way to spend a day in Sonoma.
