I find these posts infuriating... and given how old this one is, it seems to be the template for all those to follow.

"How did I get to be a world class marathoner? I avoided anything that wasn't running, and then on race day, I went faster than everyone else. It's so simple, you can do it too -- just buy my course."

The advice is reasonable, well-intentioned, and completely unusable for me or anyone else I know.
