The 2017 Grizzly Peak Century was held on Sunday May 7, 2017.
If you wish you'd ordered a T-shirt or Jersey, it may not be too late. Visit our Century Store to see what's available.
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.
Start and Finish Times
Rider check-in is 7:00 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. Overall closing time is 4:30pm (due to being only a metric century), not 6:00pm as usual. See the times page for detailed information on opening/closing times.
Route: Metric Century Only in 2017
On April 18, the bridge on Canyon Road west out of Moraga was unexpectedly and indefinitely closed. Our century route normally crosses this three times. The Lafayette-Moraga Regional Trail, which parallels the road there and which might have been used as a bypass, was already closed due to a landslide. We had to reroute. We regret that lack of time and other planning factors have forced us to offer only a single 75 mile “Metric-Plus” Century course this year. For more information see the Routes page.
Mixed Terrain Route - Status
We regret that we will not offer a Mixed Terrain Route this year. Maybe next year.
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.
- Cue sheet and road markings
- Rest stops at 15 - 20 mile intervals
- Clothing drop at the first rest stop (Island Picnic Area)
- Basic mechanic service at all rest stops
- SAG vehicle and radio support
- A fabulous post-ride barbeque
- A souvenir pair of GPC Century socks
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!
