Thanks Blast, i'm here for a 12 month placement with work, so plenty of time to get out and see the place by bike. I'll hopefully take some longer tours as well so will look for routes for those later on. For the moment i just want to get out for some weekend rides and get some miles into the legs.
I had a quick trip out to marin headlands when i first arrived (between christmas and new years), made it up Conzelman to the lookout. I don't have a car here so sarting from San Rafael is a bit out of the way, though from the looks of google maps there's some good roads out that way. I haven't seen any groups in the city so i guess most people drive out of town and ride from there. Are there any regular rides which start from the city, or at least from the GG bridge or something like that?
