Beginner 10K - Day ???

Today was a 30 min hilly run. I made a route. In fact, I've made several routes. But I wonder why I bother, because I always deviate from that route. I went a good mile or so off track today. My legs felt like they were filled with cement. The best part of this run, ironically, occurred when I was feeling at my worst. I was walking--no, slogging home--when this chica walker passed by me. And she had that contently smug "I-just-passed-you" look that we all do, myself included. But as she breezed by, I thought, "Chick, please...you're walking. I just ran."
