Bumping this up -- I just got back from a week in SF and got out to ride a few times. Beautiful scenery, but I came away less-than-impressed with the rides out there. I started my rides from the Las Campanas area, and tried a bunch from ridewithgps, but most of the rides ended up being long stretches on frontage roads. Basically, the only good ride I has was the awesome climb up to Aspen Vista.

Am I missing something? Is there a better source of gpx tracks?

Thanks!
