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.

It sells out every year, so don't delay registering!

New this year is a 52 mile "half century" route. 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!

There are now four routes to choose from, all of them very hilly: 52 miles, 76 miles; 102 miles; and 110 miles.

The 76 mile route (5750 ft. climb) consists of the North (or morning) Loop. It climbs the east side of the Oakland-Berkeley hills via Pinehurst Road, then follows the ridge up and over Grizzly Peak and into Tilden Park. It then drops down alongside San Pablo Reservoir and heads north to the edge of the Bay and the Carquinez Strait. From there it climbs McEwen Road for a run down into Franklin Canyon and Alhambra Valley, then over Pig Farm Hill and through the hills around Briones Regional Park and Reservoir. Finally, relatively easy riding on Moraga Way and Moraga Rd. takes you back to the start for lunch at mile 76.

The 102 mile route was revised in 2011. It has roughly 8000 ft. of climbing. It is the same as the 110 mile route until the new rest stop at Wayside Picnic Area in Redwood Park. Then it goes directly to the Proctor School rest stop through Anthony Chabot Regional Park, turns around, and follows the same route back. The 102 mile route is not mentioned on the registration form. Please note that unlike prior years, the route does not return to Campolindo High School until the finish.

The 110 mile route was revised in 2011. It has roughly 8550 ft. of climbing. It consists of most of the North Loop followed by a new rest stop at Wayside Picnic Area in Redwood Park. (If you feel tired or are running late at this point, consider doing the 102 mile option described below). After that you loop around Redwood and Anthony Chabot Regional Parks via Skyline Blvd and Lake Chabot Road to the Proctor School rest stop, returning via Redwood Road. Please note that unlike prior years, the route does not return to Campolindo High School until the finish.

We regret that we will not offer a Mixed Terrain Route option this year. Maybe next year.
