I have been riding a good amount lately, but giving myself downtime and other forms of exercise. My legs are just dying though, on and off the bike. Going up a couple of flights of stairs has become difficult! It is sad, and a little worriesome. I am sure some of it is a little SAD, but that doesn't explain all of it because the rest of my body is fine. I am going to go try to ride today, but I am worried it is going to be another disaster like Sunday and Monday when I had to turn around after 30 minutes.
