Grizzly Peak Century -- Sponsored by the Grizzly Peak Cyclists . Starts in Moraga, climbs up the Oakland hills, then down past Inspiration Pt to San Pablo reservoir, around the reservoir, up the very brutal McEwen Road, over the Bears along Briones reservoir, then back to lunch. That's 69 miles and 5500 feet of climbing. After lunch if you continue on the century (which I'm always too tired to do), you head south up the Oakland hills and then back. It's a beautiful, challenging ride with wonderful food. Only problem can be the weather -- it rained last year.
