British athlete Josh Kerr delivered a historic performance on Saturday, July 18, 2026, at the London Diamond League, where he ran the fastest mile in history with a time of 3 minutes, 42.66 seconds. This remarkable feat shattered the previous men's mile world record of 3:43.13, set by Moroccan runner Hicham El Guerrouj in Rome in 1999, ending a 27-year-old record, according to The Associated Press.

Kerr, 28, celebrated his achievement with a lap around London Stadium, where the crowd erupted in applause. Video footage shared by the Diamond League on X captured Kerr throwing his arms into the air after crossing the finish line.

In the same race, Britain's Jake Heyward finished third with a personal best of 3:46.73, as confirmed by official results from World Athletics.

Before turning professional, Kerr had an accomplished collegiate career at the University of New Mexico, winning three NCAA titles, eight Mountain West championships, and setting the collegiate record in the 1,500 meters.

Kerr reflected on his record-breaking run, saying, "But ... I started to glide and I was like, 'Oh wow, this feels incredible.' It's incredible because I'm slowing down. So, I was like, 'I better get to the line.' So, crossing the finish line, seeing 42-something, anything, was my goal, so it was great." He also noted, "I was absolutely deaf in that last 110 meters," and admitted, "It's very overwhelming with the amount of hype [I created]."

Saturday's performance lowered Kerr's previous personal-best mile time of 3:45.34 by nearly three seconds and erased one of track and field's longest-standing world records, according to World Athletics.
