I planned a 2 mile run and strength training today. One of my friends at work said, "Push it to the limit, run 2 1/4 miles today." So, as I was running, I thought, OK - why not? At 2 miles I started getting a little cramping in my stomach, but nothing too major, so I pushed through and ran another 1/4 of a mile then walked to cool down. It felt good to push it beyond what I had planned. One day at a time I will do this!
