My boyfriend and I are planning a 2-week trip to San Francisco (and Yosemite and Napa) in late July. We'll be bringing our road bikes and want to do some fantastic day rides. We're not sure where to begin to ask so I thought I'd start here.

We're both strong cyclists and aren't afraid of climbing so single-day rides in the 50km to 160km (30 to 100 miles) range is what we're after.

If you have suggestions of must-do scenic rides, or can give us an idea where to start gathering info from, it'd be greatly appreciated.

thanks!
