He ran the fastest mile in history, half a second faster

Scottish runner Josh Kerr ran the fastest mile in recorded history at the London Diamond League, clocking 3:42.66 and breaking a mark that had stood for 27 years. Kerr finished half a second ahead of Hicham El Guerrouj, the Moroccan whose 3:43.13 was set in Rome in 1999, when Kerr was a toddler. Pacemakers carried him to the 1,000 meter mark, then peeled away and left him to run the final stretch alone. He passed 1,500 meters at a personal best. According to World Athletics, he crossed every checkpoint faster than El Guerrouj had. Kerr had announced the attempt at the start of the year and trained in the hills of Albuquerque, New Mexico, in a camp he named "Project 222" after his target time in seconds. "I just hoped it would be a little bit faster," he told BBC Sport, sweat still on his brow. Six other runners set personal bests that night.
