On the second day of riding in Napa I rode through Pope Valley. While not quite as long it was just as demanding as the previous day. It wasn't as hot so I was able to turn up the intensity on my spin. I had one big climb up Howell Mountain, followed by rolling terrain down and around Lake Hennessey.
Riding through wine country wasn't quite like I was expecting. It was a lot more challenging than I thought, especially being so accessible to some great mountain ranges and rolling hills. The dry heat also played a major factor in my ability to cover ground. It's really a beautiful area and very popular for cycling. I passed quite a few weekend warriors who all seem to know their way around and choice routes to consider. I'm definitely looking forward to my next visit.
