Every see a marathon? New York City has a big one once a year that attracts thousands of runners, and if you stand anywhere along the course (which spans pretty much the entire city), you will see an assorted cast of characters.

They all are, without question, in fantastic shape. I mean, they’d have to be to be able to run 26 miles. But none of them seem “tough” like a fighter does. Runners are by their very nature lean and skinny and very unassuming.

Now picture seeing these dudes run by. It’s safe to say that these guys are the exception to the rule. They are the two marathoners in the world who would kick your ass like nobody’s business.
