I first attempted running about 2 1/2 years ago. I could LITERALLY not run for more than 20 seconds. I'd run/walk, run/walk, run/walk for 20-30 minutes. I quit after 6 months; by then I could run about 4 minutes non-stop. 6 months after that I started working with a personal trainer. I can now run a mile...!!! I never dreamed that would be possible. When I completed my very first mile, I think my time was 14:41. I've whittled it down to a little over 11 minutes, but like I mentioned earlier, I haven't run much in the past 3 months so I doubt I could do it right now. When I'm in the habit of going to the gym 3 - 4 times a week, though, I can actually do that mile without TOO much trouble. I tend to feel really bad right around 7 minutes, but if I push through it, around 9 minutes I get my second wind and finish the mile without any more problems.
I'd love to be able to do a 10-minute mile.
