This part that goes across the SFO runway and over the bay probably needs some detail added


I have no idea what the streets are like, but maybe consider one of the SF2G routes, like the Bayway route (out and back) or any of the variations on that page, adding extra at either end such as going over the Golden Gate, or getting to and from home to make it a door to door ride.

Or check Ride With GPS. Not only is there the SF2G Byway, but there's also the Tierra Bella Century, and the easier version.
