My wife and I chose the 3-day Wine Country and Sonoma Coast tour. I would highly recommend it for anyone that might enjoy a nice mix of road biking, wine tasting, and soaking in gorgeous terrain.
There were a total of eleven people on our tour, and we had two guides - Laura and Daryl - who were just great. They had all of the bikes ready to go each morning, and the bikes were set up based on the measurements that each person had sent in beforehand (based on their own bike from home). The bikes were super nice, full carbon.
Each morning we got together for breakfast, got route sheets and talked about the potential add-ons for those that wanted more mileage. You go at your own pace, so at times we were a group, and at other times folks or couples took off on their own. We'd re-group for a snack and also then for lunch. The highlight for me was the grueling Sweetwater climb on day 2. This was an optional segment; the others chose the flat route, so I got my own person guide (Daryl) on Sweetwater. I actually flatted prior to the climb. Probably could have fixed it myself with the tube and CO2 provided in my bag, but let Daryl handle it - what the heck, I'm on vacation!
Bottom line, the rides are beautiful - lots of redwoods, rolling vineyards, and shady creekside roads. The most beautiful stretch is the 10 miles of coastline on day 3. We will definitely be looking for another UDC Tour in the future.

Our operation was founded with a radical notion that bike tours should emphasize great bicycling before everything else. Thousands of cyclists agreed, and our dedication to a great cycling experience has made us the leading road bike tour company in California. Our tours are very different than the standard fare offered by countless other companies, however. Here are the main features that set our tours apart:
Our first priority is always producing the best imaginable bicycle vacation for those who love road cycling. Anything that makes cycling more enjoyable, we do it. For example, a great cycling experience starts with a great bike. That's why our race-ready, feather-light carbon road bikes are the highest performance bicycles offered by any tour company.
California is our home, and we specialize on providing the absolute best cycling this state has to offer.
We prefer the backroads to the main highway, the quaint village to the busy tourist town, the small historic inn to the world famous resort. We don't see many other tour companies on our travels, and we like it that way.
Crowds are not our style, so we limit our group sizes to no more than 14 people—and frequently no more than 10! This lets us fit comfortably in the smaller inns, lodges, and restaurants off the beaten path.
We believe bike tours should be about traveling by bicycle, not shuttling in a van, so we design all of our tour routes to maximize amazing bicycle travel and minimize vehicle transfers (of course, a support vehicle is on the route should you need it).
