Well, had my first run in over 4 years this morning. Unfortunately, it was really chilly for central Florida. Actually, was combo run/walk. Trying to ease back in, since I'm 41 almost, 80 lbs overweight, and the Indianapolis 500 mini marathon was almost 20 years ago. Knees are a little rough after bearing so much weight for so long. Had joint replacement fluid therapy on the left one. Good news is, my first go this am went pretty well. Did run 1 minute, walk 2 minutes for a total of 30 minutes. Over next 8 weeks, will work up to more running than walking until all 30 minutes is running.
