I'm 6' 270 lbs and I demolished 1-1/2 miles without stopping, with the help of this app. It's made so that each run is attainable, which is why the running seems almost addictive. Don't give up, stick to the program, and you'll be running distances in no time. What helped me was telling people that I was going to run a 5k. If people are always asking you about it, you will be more likely to stick to it. Kinda like accidental accountability.
