After a neutral 5-mile spin from Jack London Square through Berkeley, the road kicks up for a roughly 2-mile climb up Claremont Avenue. The next 19 miles roll up and down through Redwood Regional Park and past the Upper San Leandro Reservoir, until you drop down to the first Aid Station in the outskirts of Hayward, CA.
It is important to start Mt. Diablo with plenty of fluids. You should expect the climb to the summit Aid Station to take at least an hour. Three stages of the Amgen Tour of California have featured Mt. Diablo, and top male pro times for the south side of Mt. Diablo are about 40-45 minutes, with top female pro times at about 50-55 minutes.
The timed section of Mt. Diablo is 10 miles, encompassing about 3400 feet of elevation gain. The first seven miles meander at reasonable grades below 7%. The final three are tougher, as grades increase to 8-10%. Keep something in reserve for the final pitch, which ramps up to 15%. If you crack here you can lose a minute or more!
After enjoying the views atop Mt. Diablo, it’s time to descend. When you reach the intersection with North and South Gate Roads, turn right on to North Gate Road. The northern descent of Mt Diablo drops 3500 feet in 11 miles, and can be quite chilling, so carry appropriate clothing. Keep in mind; the descent is not timed. There are no extra points for descending like a daredevil. Have fun, but be safe.
After passing through Mt. Diablo’s North Gate you’ll ride about 30 miles of rolling terrain through Walnut Creek before starting Stage 1’s final timed segment, the 5.7-mile Grizzly Peak climb. One hint about this climb; the tricky part is the flat section in the middle!
All timing for the stage ends at the summit and you have an 8-mile downhill cruise to the finish in Jack London Square. You must cross the finish line in Jack London Square to officially finish and have your timed segments counted toward stage and overall rankings.
