The climb pretty much increases in intensity. The last mile was the most grueling for me. Even with a 1:1 gear ratio and a 3.7 w/kg ftp, I found myself quite strained to get to the top. There are some less steep bits where you can spin a bit to recover. It is quite technical descent as there are very steep hairpins, so I do not recommend descending from Quimby Rd. Instead, decent down 130 or Clayton Rd!

Really like this climb. Takes you away from city bustle through classic switchbacks and solid grade. Use it to get to Mt Hamilton if needed and it is an interesting descent.

Climb summary by PJAMM’s John Johnson.

This is a steep and challenging climb out of the Silicon Valley into a very rural area on a narrow road with minimal traffic.  We begin our climb in a suburban area near Quimby High School in East San Jose, but at the 1.1 mile mark we cross Murillo Avenue and are soon into an eclectic mix of ranchland together with the occasional Silicon Valley mansion.  If you leave in the early morning as we did, you’ll encounter roosters crowing, along with cows and horses grazing.  

Before heading to the bay area on your cycling adventure, be sure to rely on our list of Things to Bring on a Cycling Trip, and use our interactive checklist to ensure you don't forget anything.

Windy road - no problem on the ascent, but . . .

There are excellent views of the Silicon Valley and San Jose to our west as we quickly rise out of the valley (because of the elevation gain, not our speed, that's for sure!).  Along with the first sections of
Mt. Hamilton Road West and Sierra Road in Santa Clara County, this climb provides the best views of the Silicon Valley from its eastern side.

Descent:  The downhill on this one is technical and steep with very sharp turns/switchbacks that come up on you quickly, so descend with caution.

Roadway Surface and Traffic Report: The roadway is two lanes with a double yellow center stripe the entire climb.  There is minimal traffic along this route and it is safe for cyclists.
