With the weather being a bit cooler than it was last week, I decided to ride up Mt Hamilton today, from east to west, starting from Livermore. From downtown Livermore, it is a about 49 miles to the summit (at about 4300 ft), which makes it tougher to climb from this side. What is more challenging is that, the final climb of about 2000ft happens in just about six miles (i.e. from mile 43). These six miles are grueling, with an average 9-10% grade, and I could not average more than 4 miles/hour during this segment. My GPS puts the cumulative ascent at 6500ft, although my legs are trying to make me believe that it is much more than that.
