Did about 16 miles on the C&O Canal towpath yesterday. I had intended to do about 30 miles, but had bad legs and even the 16 miles was an effort. Of course, I kept checking the bike to find some reason that it was the problem and not me But, no flat tire, no rubbing brake pads, just a pooped pedaler. I finally realized that I was more tired than I thought when I fell asleep on the side of the towpath on one of my breaks. Gorgeous weather, though, so I just stared at the beautiful views of the Potomac River as I pushed myself to pedal in circles instead of squares. Today's definitely gonna be a rest day.
