The 2017 Grizzly Peak Century will be held on Sunday May 7, 2017.
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.
Rider check-in is 6:30 am to 8:30 am at Campolindo (7:30 am to 10:00 am at Island Picnic Area in Tilden Park if you use the alternative car-free start). We urge slower riders to get an early morning start.
Standard Route Options
There are three standard routes to choose from, all of them very hilly: 76 miles, 102 miles, and 110 miles. The routes are identical for the first 73 miles (the north loop), at which point the metric century route returns to the finish while the two full century routes continue onto the south loop. For more information see the Routes page.
Mixed Terrain Route Options - New!
In addition to our standard routes, we hope to repeat last year's successful Mixed Terrain routes: 78 miles and 100 miles. Registration for these options will probably be limited. For last year's information see our Mixed Terrain Details page.
Entry fees for 2017 range from $60 (early registration) to $80 (century day, if available). The ride is limited to 1,000 riders and has sold out for many years, so you should register early if possible. We also have a variety of century-related items available for purchase when you register.

Century Prep Rides
Join us for a series of nine rides for intermediate bicyclists who want to build stamina and increase range. The rides will be on consecutive Sundays, beginning February 28, and will gradually progress in distance from about 25 to about 55 miles. All are over moderately hilly terrain, similar to that of the 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.

Every year since 1975 the Grizzly Peak Cyclists have hosted the Grizzly Peak Century. The event is known for its challenging but beautiful terrain and gourmet home-made food. This page has only the basic information. There are many more details on the rest of the site.
Donations (Where does my fee go?)
We donate most of the proceeds raised from our 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.
Let our motto be your guide —
Ride to Eat and Eat to Ride!
