The Chain Reaction website has some very nice routes mapped out, many with photos.
http://www.chainreaction.com/theloop.htm --> the Most Excellent Woodside / Portola Valley (mini) loop
http://www.chainreaction.com/bigloop.htm --> the beefier version of the mini loop, which adds Old La Honda up and the descent down 84 (not for the faint of heart, but quite the blast, I think!)
http://www.chainreaction.com/coastloop.htm --> Pescadero/Tunitas Creek. This one is for the studly.
