Grizzly Peak Century Ride

This event is hosted by the Grizzly Peak Cyclists.

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 year's century ride takes place Sunday May 5, 2019.

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 Times
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.

Route Options
There are three routes to choose from, all of them very hilly: 52 miles, 76 miles, and 102 miles. The latter two routes are identical for the first 73 miles (the north loop), at which point the metric century route returns to the finish while the full century route continues on to the south. For more information see the Routes page.

After a very popular debut in 2018 the 52 mile "half century" returns this year. This route is the heart of our longer north loop route, offering plenty of climbing, great views, and a sufficient amount of exercise. It is the Century Chairperson's favorite option!

We have dropped the 110 mile route this year in favor of the safer and more scenic 102 mile out-and back on Redwood Road.

Entry fees for 2019 range from $65 (early registration) to $85 (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.
