One part mad science, one part human determination, Nike's sub-2 marathon event was a riveting, aggressive source of fascination for anyone who's ever ran a marathon. Why? Because running a marathon in under two hours would require a man to run 26.2 miles at a 4:41 pace per mile. Nike's team of scientists set out to control every factor--nutrition, shoes, weather, location, training, drafting--even going so far as choosing three genetically gifted Eastern African runners and monitoring their every move for months leading up to the attempt.
When the three men finally lined up at the Formula One Track in Monza, Italy, millions of spectators tuned in to a Twitter livestream and were not disappointed. Eliud Kipchoge, the 34-year-old Kenyan-born 2016 Olympic marathon gold medalist, finished in a mind-blowing 2:00:25, brushing up against a barrier that most thought was impossible to break. Call it the moon landing of running--we're ready to see someone shave those 26 seconds off.
