This was our longest hike since we started training. This area of the Montebello Preserve is beautiful; it has fantastic views of the bay area. We had different microclimates along the walk. It was warm at the bottom of the mountain, so we, the inexpert hikers, left our jackets in the car. By the time we reached the top of Black Mountain, it was cool and windy, probably 10 degrees cooler. We only stayed for 10 minutes and turned around to descend because we were cold. We learned that higher altitude means cool temperatures, and no matter what, always bring a warm jacket in your bag.
We hiked 10.13 miles.
