I just started the C25K this week, and while it's hard getting mvoing again, I absolutely love it. It's a 9 week program, and you run 3 times a week. I found a podcast that helps keep time for this first week, and now even my 12yo is using it. Unfortunately, because I'm still new to the forum I can't post the link, but if you do a search for cool running c25k, it'll take you right to it.
I talked a gal I work with into starting it at the same time, and now we're already collaborating and conspiring to talk other coworkers into starting it as well, and getting a job 5K team together for charity runs.
Good luck! And keep us informed on how you are doing!
