My shin seems to be much better now which truly makes me a happy person. Yesterday's walk left me only slightly stiff today and I got on the treadmill with a smile. Since it had been a while, I chose to do a 1-minute-run/1-minute-walk session so that I knew I would finish with that same smile. At the end (around the 25 minute point) I decided to just run until I couldn't. It was my calves that finally prompted me to slow down since they were on fire. And that was after I'd run a solid 5 minutes. I wasn't smiling anymore, I was grinning! What will tomorrow bring? I'm predicting another smile.
