50 MARATHONS IN 50 DAYS: This guy’s a machine. Or maybe an eating machine:

You wouldn’t believe the stuff Karnazes consumes on a run. He carries a cell phone and regularly orders an extra-large Hawaiian pizza. The delivery car waits for him at an intersection, and when he gets there he grabs the pie and rams the whole thing down his gullet on the go. The trick: Roll it up for easy scarfing. He’ll chase the pizza with cheesecake, cinnamon buns, chocolate éclairs, and all-natural cookies. The high-fat pig-out fuels Karnazes’ long jaunts, which can burn more than 9,000 calories a day.

I’m speechless.
