Can a human run a marathon in two hours flat? The documentary Breaking2 follows three elite runners as they attempt to break one of the most famous barriers in sport — maintaining 26.2 four-minute, 34-second miles.
One of those runners, Olympic gold medalist Eliud Kipchoge, of Kenya, came 25 seconds shy of the two-hour mark with a time of 2:00:25. "The world now is just 25 seconds away," Kipchoge says in the film.
"I'm not afraid to say when he crossed the line I cried," filmmaker Martin Desmond Roe tells NPR.
