This is my 2nd time here. Should I be writing here or should this be a "new topic"? Anyway, the important thing is I DID use the C25K app again today - my 2nd day in a row. Although I can't run every 'run'section, I'm doing every other one and walking briskly in between. For me, this is amazing! As I said yesterday, I haven't run in years! I am feeling kind of sore and achy tonight though. - Lilylover
