The Grizzly Peak Cyclists have hosted the annual Grizzly Peak Century since 1975. The event is known for its challenging but beautiful terrain and gourmet home-made food. Due to COVID-19 we were forced to cancel the 2020 GPC Century and we are currently holding the fully supported ride on Sept. 12, 2021. A do it yourself version is available from Aug. 28th thru Sept. 11th.

The main start/finish and post-ride meal location is Campolindo High School, 300 Moraga Rd, Moraga, CA. Parking at Campolindo is limited, so if you are driving there, please try to carpool with other riders if you can. We also offer a car-free alternative start in Tilden Park. For details on both options see our Start Locations page.

There are three routes to choose from, all of them very hilly: 50 miles, 75 miles, and 100 miles. The latter two routes are identical for the first 73 miles (the north loop), at which point the 75 mile route returns to the finish while the full century route continues on to the south.
