Yesterday I learned a valuable lesson while I was running: Don't run with out a plan! I started out on the treadmill knowing I was going to run but not really thinking about how fast or far I wanted to run. About 13 minutes into my run I wanted to QUIT bigtime! I did manage to push through and finish 30 minutes and almost 2 miles but it was HARD. Lesson learned, next time I will have a plan.
