Also, I want to climb every hill in the area, so any suggestions for new ones are welcome.
If you are ever in the East Bay / Vacaville area, Winters- Cantelow Loop is a classic ride with a classic hill. Most people start in Winters down the frontage road to the South, West across the English Hills (good warmups) then up over Cantelow, North on Pleasant's Valley to Putah Creek Rd then East for a quick return to Winters. IMO, one of the best rides around. Check out the map/profile here (not my data):
Winters - Cantelow LoopI did it today and averaged 20.1 mph, so I was pretty psyched given that there is a good amount of climbing and there was also a decent 15 mph wind blowing.
Probably my most favorite ride in all of Northern California that I have done so far is the Silverado Trail Loop (Napa to Calistoga). Nothing but wide shoulders, good pavement, and vineyards/wineries the whole way. Usually a light breeze, but the area has its own microclimate. Sometimes it is smoking hot in Vacaville and I'll drive out there and there will be a cool breeze and a light marine layer. Perfect riding weather! (also, not my data)
