Have not posted as this name before.I graduated on the Couch to 5K a few years ago but I can honestly say I never really enjoyed running so I didn't keep it up. Now at the age of 64 I find myself being a little interested again. I find I am scared of not being able to breathe again like before (but know I did). I wish I had the enthusiasm before running as I do when I finish. I always think people look as if they are really enjoying running.
