I've heard a few people using Couch to 10k, but most folks I know just run.
We own the book Jack Daniels Running Formula and it has a number of training plans as well as a wealth of information and super interesting tidbits. We just leave it by the bed and I open it on a whim and invariably read something interesting and usually useful. I like The Lore of Running by Timothy Noakes for the same reason. Actually, I think I like Noakes better. Anyway, if you are into running and a book kind of person, I'd recommend either or both.
