So I decided that since I had to take yesterday (Friday) off work anyway, that I may as well see if this pulled muscle in my chest was going to stop me from running in a race next week. I thought I'd go back to my favorite haunt, Richardson Park, and try to see how I go. I wasn't planning on PR'ing anything, just surviving, which I did. Any really big breaths were a strain, but the normal run of the mill stuff was fine, so I'm good to go in my book. Incidentally I did 3.13 miles in 30m43s.
