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.


Century Planning Meeting - Tue Nov 27

The next planning meeting for our 2019 Century will be Tue Nov 27, 6:30pm, at the home of Janet Noble and Brian Aldrich in Oakland. Century coordinators in particular are encouraged to attend; so are all club members who want to help plan the century. Contact Brian,, for more info, the address, and to RSVP (required). For general info, see our Century Planning Policy. Planning meetings occur approximately once per month up to the Century.

Cyclist Video Evidence

If you use a bike-cam, upload your video recordings of incidents with motorists to this website: They maintain a searchable database of motorists who have harassed and/or assaulted cyclists. The more accumulated video evidence, the better. You can use it to track repeat offenders — and the justice system can use it too.  Over time, more bike cameras and more evidence will bring better driver behavior.

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.

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.

Let our motto be your guide
Ride to Eat and Eat to Ride!
