Josh Kerr breaks men's mile world record at London Diamond League

Josh Kerr has broken the men's mile world record, clocking a time of 3:42.66 on Saturday, July 18, 2026, at the Novuna London Athletics Meet. The Edinburgh-born runner surpassed the mark of 3:43.13 set by Morocco's Hicham El Guerrouj in Rome in 1999, ending a record that had stood for 27 years according to AP News.

The performance was the culmination of Project 222, an eight-month specialized build named for the target number of seconds Kerr wanted to run. According to Npr, the project involved a laser-focus on the time goal, featuring training in the high altitude of Albuquerque, New Mexico, and recovery ice baths lasting 222 seconds.

Competing at London Stadium before a sell-out crowd of 60,000, Kerr utilized a strategic pacing plan. He was led through 800m by Brooks Beasts teammate Brandon Kidder and then by Zan Rudolf to the 1,000m mark, reported The New York Times.

Kerr hit the 1,500m mark in 3:27.62, which is faster than his own British record for that distance. He maintained his form over the final stretch, recording 13.7 seconds for each of the last three 100m splits, according to BBC. Kerr finished more than three seconds ahead of second-place finisher Yared Nuguse of the United States, who ran a 3:45.69.

A Legacy Reclaimed

The victory makes Kerr the seventh British man to hold the mile world record and the first to do so since Steve Cram in 1985. This lineage includes Sir Roger Bannister, who first broke the four-minute barrier in 1954, as well as Sebastian Coe and Steve Ovett. Coe and Ovett traded the record three times over 10 days in 1981, according to NPR.

"If I am to leave my mark on this sport as a British legend, following in the footsteps of the legends behind me, I have to put in those performances,"

Former record holder Sir Sebastian Coe described the achievement as unbelievable and foot-perfect, noting Kerr's mental resilience in front of the massive crowd, as reported by the Daily Mail. Steve Cram told BBC Sport that the world mile record perhaps surpasses everything and welcomed Kerr to the club.

Technical Preparation and Equipment

Kerr’s attempt was supported by bespoke gear from sponsors Brooks. According to BBC, the equipment included:

• Speed Suit: A bespoke all-in-one featuring laser-cut perforations to improve breathability in the July heat and enhance aerodynamics.
• Custom Spikes: Shoes designed for Kerr's specific biomechanics, featuring titanium pins to reduce weight and a carbon plate with an aggressive rocker for propulsion.

Leading up to the event, Kerr’s coach, Danny Mackey, noted that the athlete had targeted the record since returning from a calf injury that hampered his gold medal bid at the World Championships in Tokyo last September. Kerr also documented a 1,200m time trial in Albuquerque, clocking 2:42.45.

Wider Context and Other Results

Kerr chose to target the mile this year because the 2026 season does not culminate in a major global championship. This follows years of intense rivalry in the 1,500m with Jakob Ingebrigtsen. In the 2024 Paris Olympics, Kerr earned silver while Ingebrigtsen finished fourth. At the most recent World Championships, Kerr pulled up lame and limped into the finish of a race won by Portugal's Issac Nader.

The London Diamond League meet featured other notable performances. Cierra Jackson won the women's discus with a Diamond League record throw of 71.72m. In the women's 800m, Keely Hodgkinson won in 1:56.21. In the pole vault, Sam Kendricks took first place on countback after world record-holder Mondo Duplantis withdrew due to an injury, as reported by The New York Times.

For his record-breaking run, Kerr was presented with a cheque for £38,000, as reported by the Daily Mail, though Rnz cited the amount as $50,000.
