A description of local climbs is available from Stanford Cycling. This wonderful compilation is largely the work of Sergei Morozov, who unfortunately last time I checked was in exile in New York City. A frustrating fate for a climbing addict....
Keith Vetter's Klimb is a must-see route tracking utility for the San Francisco Bay area and Sonoma. It runs on a broad range of platforms. If you are thinking of charting out a route, you really need to give this a look. It's largely based on Bill Bushnell's comprehensive statistics, meticulously collected in the 1990's.
Another must-have local resource is The Krebs cycling map. It's not available at a bike shop in the Bay area, it's probably just because it's out of stock.
Local rides worth checking out, off the top of my head. There's others: a more comprehensive, not 100% up-to-date, list is maintained by Fremont Freewheelers:
- The Palo Alto Morning Ride: leaves 6:20am Tue & Thu from Starbucks on University Ave. Fast group ride with sprints.
- The Noon Ride, leaves noon SHARP from Page Mill and Old Page Mill near Foothill/Junipero Serra:
- Mon: short, moderate pace,
- Tue: race pace, longer. For example, here's motionbased data of the Corte Madera route.
- Wed: climb OLH (390 vertical meters), descend 84. For example, here's some of Chris Hipps' data.
- Thu: like Tue.
- Fri: like Mon but longer, blast over short hill at end with sprint after.
- Wed 9:10 am, Peets in Los Altos, Dave's Morning Ride: epic stuff. Really high quality riders, friendly, quality race training. Of course, work has a pesky tendency to get in the way of this one.
- Saturday: Spectrum Ride, approx 9:15 am from Los Altos (Foothill @ Edith) catching the group which starts 9am further south. Similar to Tue/Thu noon ride, but faster.
- Saturday, Peets in Los Altos, 9:10 am: Alto Velo B ride: a moderate pace group ride with climbing with generous regroups.
- Sunday, Peets in Los Altos, 9-9:10 am: Alto Velo A ride: a fast group ride with considerable climbing and limited regroups. Hard road race training.
- sanctioned races: See http://www.ncnca.org/ and http://www.ncncaracing.com/
- The Beat the Clock Series raises money for the the Lance Armstrong Foundation with its occasional time trials on Canada Road starting at 7:30 am.
- touring rides: interesting routes, with very generous regroups: Western Wheelers . Also Grizzly Peak Cyclists and the Alameda County Touring Cyclists occasionally organize group rides on the Peninsula.
