Notes
First foray into Greenbelt Park. It's quite hilly. I took it very easy. Around 8 miles, I got a strange pain in the left side of my chest and stopped. It came back when I tried to run again, so I walked a long way. Eventually I realized that, in my puny state, I had probably strained a rib muscles yesterday by briefly carrying a dresser, and swinging my arms while running aggravated it. After Grandma's I really need to do some strength work.
