After a day of riding 65 hilly miles, my legs felt like concrete. Yesterday I was walking around like Frankenstein. In a fit of sanity, I took the day off.
Today my legs felt much better. I decided to go for a spin but before I began I raised my saddle a smidgen. Small changes to saddle height and other bicycle settings can make an enormous difference in comfort. Just a couple of millimeters was all it took to calm my sore left knee. I had no pain at all during my 35-mile ride up to DC and back. The change also seemed to help my lower back.
About a mile from home, I pulled The Mule over to take a picture..

I am beginning to wonder whether The Mule will outlast me.
