Buy a Garmin fitness tracker and join the PF group! When I started in April, I could not run a quarter mile without stopping. Last Saturday I had a total distance of 5 miles, but a considerable portion of that was walking because my dog is so out of shape. Anyway, running 3-4 miles without stopping is not difficult for me now. I've been amazed at what getting on the treadmill 2-3 times a week has done for my overall fitness, and the Garmin thread deserves most of the credit for that. It's been a huge help to me.
In other news, my weight today was 169.6. Today is the first time my pre-run weight has been under 170. When I started participating in this thread, my weight was 190, and I picked 170 as my goal weight. I'm revising my target goal down to 160 now. The most recent three pounds were rather difficult to lose, but a couple of days with pretty severe caloric restriction did the trick. The next ten pounds might be pretty miserable, but I'm certain the goal is attainable.
