Couch to 5k-I Just started...looking for advice!

I've done the program through more than once. Do it whatever days works for you, but leave day between each running day for recovery. You can do other exercise on those days, even walking. It you don't feel ready to move on to the next week, or the next step, repeat until you are. But push yourself. Pretty much anyone can run physically run 5 kms after some work, but the hard part is the mental. Don't give up on the long runs when they come. Just keep putting one foot in front of another. Read up on how to breath properly and most of all, enjoy the process of becoming a runner.
