Primavera Century

April 18 2021
Fremont, California, USA

The Primavera Century covers some of East Bay’s most scenic roads.  The longer-distance routes ride past the historic Mission San Jose to the scenic Calaveras Reservoir (part of past Amgen Tour of California Routes and home to Bald Eagles), along beautiful tree lined lanes, through vineyards, to the top of Altamont Pass, past wind turbines and through scenic canyons. The 25-mile Fun Ride goes through Coyote Hills Park with abundant wildlife.

Primavera Century


Complete Century: 100 miles, 5,500′ ascent
Travel through Fremont past historic Mission San Jose along the foothills up Calaveras Road and “the Wall”. Then enjoy sweeping views of Calaveras Reservoir along roads used for the Amgen Tour of California. If you are lucky, you will see Bald Eagles. Then it is to Sunol, Pleasanton, and Livermore and to the top of Altamont Pass, past wind turbines and down into Livermore along more Tour of California roads for lunch at Rios Lovell Winery. Then it is up the Dublin Grade and quiet Palomares Road to Niles Canyon and back to Fremont for a hearty meal. Total elevation gain is approximately 5,500 ft.

85 Mile Option, 4,300′ ascent
The Century route without the Altamont Pass.

The Perfect Metric: 100k, 63 miles, 3,800′ ascent

The Calaveras Loop: 65k, 40 miles, 2,100′ ascent
Get a workout on “the Wall” then enjoy the scenery. Follow the Century route to and around the Calaveras Reservoir and then cycle Niles Canyon to your celebration lunch. Total elevation gain is 2,100 ft.
