i dont want to

Well, I really didn't want to go to the track today, but I have gotten myself in the habit of when I get home immediately putting on my sweats and running shoes. I have found I am more likely to go that way. So I went. I began the same workout as Monday and Tuesday but after three laps my the outside of my left leg felt so tight I couldn't extend it. So I walked the next mile and a quarter at a slower pace than normal. Then the last two laps I was able to run the ) again and my leg didn't hurt. Weird.
