Start this loop along Piedmont Avenue for a brief warm up before the infamous climb up the steeps of Sierra Road. A relatively quiet, two-lane country road, Sierra starts out as a gradual climb, but quickly amps up to a grinding 10 percent grade. Along the way, expansive views of Silicon Valley reward, but the view from the Sierra Road summit is the real payoff. Glide down Felter Road, carefully navigating a few sharp turns that could be tricky at high speeds. Round out the ride with a relaxing spin down Calaveras Road and Piedmont Avenue. Note: Sierra Road is doable (but challenging) on a double. However, don’t be shy about using easier gear ratios if you have them.
