I can start in Oakland/Berkeley. I need the ride to end in Hayward no later than 12:00. You can take BART home from Hayward (or Castro Valley) if you want. I am thinking that we'd leave Oakland/Berkeley by 8 or 9 and ride for about 40 miles through the hills to end up in Hayward.

This is the basic route, which I can do in two hours (door to door): http://trail.motionbased.com/trail/activity/4406918

To add the additional miles, maybe it would work to go up to Inspiration Point, drop down Wildcat, go through Moraga, and reconnect to the main route on Canyon. Something like this: http://maps.google.com/maps?f=d&hl=e...5&ie=UTF8&z=14 (about 38 miles).

Let me know if you are interested.
