TRC BREAKING NEWS: Josh Kerr Smashes the Mile World Record

WOW! History was made at the London Diamond League as Josh Kerr ran a mind-blowing 3:42.66 to break the men's mile world record, a mark that had stood since 1999, when Hicham El Guerrouj set it.

Andy and Sarah unpack one of the greatest middle-distance performances we've ever seen, looking at the numbers behind the run and why it's such a landmark moment for the sport.

Andy shares his own personal experience, having ranked number one in the world for the mile when he ran 3:49.38 in Oslo in 2008. He explains just how hard it is to run this event at the highest level, talks through how the race unfolded, and breaks down the perfectly executed pacing strategy that helped make history.

Sarah, meanwhile, puts Josh's speed into context in her own way... by comparing it to the speed of a cat.
