Would people be interested in an article on "How to Run a Marathon the Hard Way"? There's a ton of stuff out there on how to run a marathon in four months and survive it, but not very much on how to spend two years gradually working up through the shorter distances so you can feel completely prepared for the marathon.
I think there's a lot of enjoyment from the shorter races that it's easy to miss out on from just moving straight up to the marathon. The camaraderie in most local road races and running clubs is great, and can really improve both your social life and enjoyment of running.
