another early morning run

I wasn't able to get in all of my "normal" runs this week, but I did manage another run this morning. Quite a difference (almost night and day -- literally). While I ran Tuesday's run at 8pm, with it still light out, I ran this morning at 5:30 am, with it still dark out. I am hoping that work evens out and I can start getting my running back to a normal schedule...I am tired...
