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 Registration Open, Volunteers Needed

Registration is now open for the 2017 Grizzly Peak Century to be held on May 7. Volunteers are always needed to help. We have opportunities on century-day itself and also in the days before and after — so you can both ride and volunteer, if you like. Volunteers get a T-shirt and a Ride-Leader credit.

Century South Loop Route Change and More

Due to winter storm damage, Redwood Road is closed south of Marciel Road (info here).   As a result, we are changing the south loop of the Grizzly Peak Century.  For more information see our our Century website routes page.

We have just learned that Canyon Rd out of Moraga is closed and the Lafayette-Moraga trail that could have been an alternate is also closed. Regretfully, the lack of time and other planning factors have forced us to offer only a single 70+ mile route this year. More info will be on the Century website routes page as we develop it.

Century-Prep Ride Series, Mar 5 - Apr 30

Join us for a series of nine weekly rides for intermediate bicyclists who want to build stamina, increase range, and get ready to ride a Century. They are on consecutive Sundays, from March 5 up to the week before our Century. They gradually progress in distance from about 25 to about 50 miles. All are over moderately hilly terrain, similar to that of the Grizzly Peak Century. Those who complete the series should be well-prepared to ride at least the 76-mile (metric century) route. For more information see our Century Prep Series page.

Pre-Registering for Rides

Ride leaders now have the option to accept pre-registration for their rides. If a leader has enabled this feature, you will find a link to register in the online ride listing. More information is on our pre-registration information page.

Ride Leading - Email Submission of Sign-In Sheets

Ride leaders may now submit a scanned PDF file of the ride sign-in sheet by email, rather than using postal mail to submit the original paper. See the instructions posted here.

Road Closures From Winter Storms

This winter's repeated heavy storms have caused many roads to wash out and close. Many of our standard routes are unusable. 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.

New feature: Member Finder tool

If you can't find your membership roster or if you need up-to-the-minute information, you can search for another member using our new Member Finder tool. You must log in to use the tool.

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