Marathon Maniacs: are you one?

You've seen these folks at races, but have you ever wondered what it takes to get into this crazy group of runners? They list their criteria on the website but the lowest level - Bronze Level - requires the runner to complete one of two things: 1) two marathons in a 16 day period or 2) three marathons in a 90 day period. I'm not interested in pursuing this for myself, but I find their group interesting. These runners always seem to be having THE BEST time at races. What do you make of them?
