Huh?

I'm not really sure how one run could be so awful and then the next be amazing. I just finished four miles with an average pace of 8:51. That's a new PR for me. What's different today compared to Saturday? Well, let's see... it was sunny on Saturday and today it's trying to rain, Saturday I ran at home and today I'm on campus, I'm wearing a different shirt than I was on Saturday, oh yes and the Moon is now in Sagittarius. Somehow I doubt any of those things really mattered. I guess I'll have to add it to the list of things I'll never understand. Now I'm going to go enjoy my new-PR-post-run high.
