Also, you are in a great area to link up with any number of rides in and around the East Bay Hills. Check out the Strava Heat Map for this area (in red), there are an absolute ton of really nice roads to ride, good climbs, excellent views, pleasant weather...
There's also a few nice rides going south, down to Sunol then back up over Palomares Rd, although riding in Niles Canyon is honestly scary as heck...
