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.

Novice Ride Series, Sun Aug 4 - Sun Sep 8

Come join us for a series of rides on six consecutive Sundays, starting August 4, expressly designed for less experienced bicyclists who want to ride more, and in the process increase their cycling abilities. See what makes us happy to be outside and riding with our friends. We start with some almost flat routes and work our way up to a 40+ mile ride in West Marin. We'll have a team of experienced ride leaders to help you with the course and teach about basic safety and the well-being of your bike. For details, see our Novice Series page and our current ride schedule.

Donation Committee Meeting Tuesday Sept 10

If you would like to help assemble this year’s donation proposal, please come to the donation meeting. All members are welcome to participate. The meeting will be at 7:00 pm on Tuesday September 10 at the home of the Committee Chair, JAZ Zaitlin. Contact her for the address.

In order to keep the meeting on schedule, we have evolved a structured way to prepare the proposal. If this will be your first time at the donation meeting, please contact JAZ in advance at DonationsChair at grizz dot org so that you’ll know what to expect and so that you can review the donation requests. Plan on at least an hour of reading in advance, so that you’ll be up to speed. Also see our donations page.
