I did it and loved it - highly recommend it. I did it, stuck with it faithfully ran, a 5K, and after that kept running and maxed out at 4 miles a day due to time contraints. I did back down a bit and kept running 2 miles 3 times a week and worked out the other 3 days (I always take sundays off). I kept it up for 3 years until I got preggo, I continued running until I got sick at six weeks. By the time I felt better, I was too out of shape to pick up running, so I walked until the end. I'm now starting over and using the couch to 5 k. Good Luck!!
