How do you choose your marathon training program?

Jeff Galloway says run four days a week, take walk breaks, do long runs.

Bob Glover says to run five, and doesn't really talk about walk breaks.
I like Running Chick's schedule - and she did her first marathon in just over four hours, which kicked ass.

Part of my brain is telling me that the Galloway program is the way to go. He's got a 98 percent success rate.

I've always believed that if a thing's worth doing, it's worth doing to excess. And the idea of the Galloway walk break method doesn't appeal to me as much. I like driving myself hard when I run.

I need to decide this and draw it up pretty damn fast. I will probably go for the Galloway - because I would like to run this thing and live to tell the tale. But I'd love any ideas or feedback.
