Grizzly Peak Cyclists

Come Ride With Us

Welcome! Grizzly Peak Cyclists is a bicycle club of about 600 members based in Berkeley, California.

We have club rides every weekend throughout the year, and many weekdays too. Roughly half our rides are in the East Bay; the rest are all over the San Francisco Bay Area, and beyond. Our ride calendar is posted every month on this website and in our newsletter. Our members' riding interests run the gamut. We have novices, intermediates, advanceds, and everything in between. Our rides are correspondingly diverse.

Anyone is welcome on our rides. Each ride is rated to indicate the expected terrain, pace, and distance, so you can choose a ride suited to your abilities. Be sure to review our rider guidelines before your first ride to avoid any surprises. Advance signup is not necessary, but feel free to contact a ride's leader in advance with any questions.

Grizzly Peak Century

Every year since 1975 we have hosted the Grizzly Peak Century. The event is known for its challenging but beautiful terrain and gourmet home-made food. For more information, see our century website. We hope to see you there on the first Sunday in May.


Every year, we make significant donations out of the proceeds raised from our Grizzly Peak Century to organizations and causes that promote or help bicycling in some way — be it advocacy, safety, education, awareness, or the bicycling environment. See our donations page for details.

Strava Club

GPC members are invited to join our Strava club. For more information see our member benefits page.


Road Closures From Winter Storms

Many of our favorite roads were washed out and closed in the winter of 2016-17 due to heavy storms.  By now, most have reopened but not all. Redwood Road reopened on March 30, 2018. Calaveras Road is still closed; currently expected to reopen in late 2018. BikeEastBay has a web page with (reasonably) current status for Alameda and Contra Costa Counties. It includes links to various County web pages for more up-to-date info.

San Antonio Valley Road, which runs from Mt Hamilton east to San Antonio Junction (Mines Rd / Del Puerto Canyon Rd) is closed to through traffic for repairs during certain hours.  Closure information is posted by Santa Clara County, here.  As of May 18, 2018 it is said to be closed Mon-Sat 8:30am-4:00pm, and is expected to reopen on May 25.

Bear Creek Rd and Camino Pablo - EBMUD Truck Traffic

EBMUD will be running heavy truck traffic near Orinda, on Camino Pablo and Bear Creek Rd, from Hwy 24 to about halfway up Pumphouse Grade.  Dates are April 23 through October 2018.  Hours are typically 7am-3:30pm, M-F.  More information and a map are here.

Hazard Reporting

You can report potholes and other bicycle hazards on the Bike East Bay hazard reporting page. The excellent volunteers at Bike East Bay will send it on to the correct public works department and will follow up if necessary. General info about the Bike East Bay hazard reporting program is here.
