Marathons sound exhausting...at least to those of us that are non-runners. But the people who lead the marathons and finish first make it look effortless. 26 miles? Psh. Asics set out to show how much of a superhuman feat it actually is for those runners so quickly by allowing people to try and run at the pace they run the entire marathon (see above video). Um yeah - not easy. Even for a minute.
