I'm in the middle of Couch-to-5k. It's a running plan for beginners, intended to take you from couch potato to 5k runner in 9 weeks.
I got through most of the program last year, and "ran" (jogged/walked) the Run Through the Jungle 5k to benefit the Exotic Feline Rescue Center, a really awesome place, check it out - it's about a 1.5 hour drive from Indy). I finished in 39:29, but the course was a little short...keeping on the same pace with 3.1 miles I would have come in at 42-43 minutes.
Fairly soon after the race I stopped running altogether, but I've started from the beginning now and am determined to become a (slow, plodding) runner. Long term goal: to participate in a half marathon at Disney.
I decided, since I'm a bit heavier now than I was when I did this program last year, that I would take 2 weeks for every 1 on the plan. So it's taking me twice as long, but I still feel like I'm getting a good workout for someone who was sedentary 8 weeks ago! I might give up the 2-week idea a little farther on in the program, but for now it's working well.
Last night I started Week 4 - intervals with a total of 16 minutes running. I use the term running loosely, of course...I set the treadmill at 4 mph and jog. I'm not worried so much about speed at this point, just stamina.
I plan on signing up for the same race this year. Maybe if I'm dedicated I can finish in better time! I should start keeping track of my miles so I have an idea of my pace.
