So far, so good with the running program. In the first week I experienced only mild discomfort in my feet and calves, however I can tell I’m definitely giving my lower legs a strong workout. Yesterday I started my 2nd week of the couch to 5k regimen, running 2 minutes on, 1 minute off. I ran closer to 40 minutes than the 30 minutes recommended and I paid for it with blisters near my pinky toes from my Vibram shoes. My calves were also complaining a lot. For my next run I’ll scale back.
