3.15 MON - I finally got back out there today! WOO-HOO !! With my new Ironman watch, which has an interval alarm, it was easy to keep track of the run/walk timing. I have it set to count down 3 mins, then 1 min and so on. The workout was easier than I had anticipated. And no burning shin pain! I think it's because I'm about 10 lbs lighter!
