I've tried couch to 5k a few times. I get to about week 3 or 4 and it's too hard. I've tried repeating a week but I still can't do it. My fitness is pretty crap and I'm about 7 stone overweight. Actually my fitness for 7 stone overweight is probably better than most in that position. I walk a fair amount. I walked more than 5 miles yesterday without any issues but running is so much harder. The minute I get to a hill (even at a walk) it kills me. Is there anything pre couch to 5k I could do to help?
