I still don't get running marathons or the whole ironman thing either. K I get it in one day you might could go further than I because you exercise all the time to train to run _________ miles etc etc. but when the apcollypse hits - I'm the guy that's fixing the yellow hummer on the side of the road so I can leave and make up lots of miles. Or - When the SHTF for real I train at the gun range so I can hit something 50 yards away. but I sure as hell can't and won't run 26 miles. meh. I get everyone needs a hobby.
