Josh Kerr ran 3:42.66 for the mile at the London Diamond League on July 18, breaking one of athletics' longest-standing world records.
The British runner took 0.47 seconds off Hicham El Guerrouj's 3:43.13 mark from Rome in 1999. World Athletics currently lists Kerr's performance as WR(p), the designation used while a record awaits the sport's standard ratification process.
Kerr Breaks 3:43 Barrier
Kerr became the first man to complete an outdoor mile in under 3 minutes 43 seconds. His 3:42.66 finish ended El Guerrouj's 27-year hold on the record in front of a reported 60,000 spectators at London Stadium.
The result was not a narrow win disguised as a record attempt. American Yared Nuguse finished second in 3:45.69, more than three seconds behind Kerr. Britain's Jake Heyward placed third with a personal best of 3:46.73, while Robert Farken ran a German record of 3:46.82 in fourth.
Kerr entered the race with a previous mile best of 3:45.34, set in Eugene in 2024. He therefore improved his personal record by 2.68 seconds while moving beyond a mark that had survived changes in competition, pacing technology and shoe design since the late 1990s.
The result also placed the mile record back with a British runner for the first time since Steve Cram held it in 1985.
Project 222 Delivered
Kerr built the attempt around Project 222, named for his goal of running the mile in approximately 222 seconds.
His official time converts to 222.66 seconds. That means the project did not literally produce a sub-222-second mile, but it delivered the more important competitive target: finishing faster than El Guerrouj's 223.13-second record.
That distinction matters because the campaign was framed around both a memorable number and an official record. Kerr achieved the latter without needing the stopwatch to display 3:41 or 3:42.00 exactly.
The public commitment also made the attempt unusual. Kerr announced months beforehand that he would attack the record in London, allowing organizers, pacemakers and spectators to understand the race's purpose before the gun.
This was not an unexpected record emerging from a tactical contest. It was a planned assault in which the athlete accepted that success or failure would be measured against one precise line.
Pacing Built the Record
Training partner Brannon Kidder and Žan Rudolf handled the early pacing. Kidder reached 400 metres in 54.75 seconds, with Kerr following in 55.3, and Kerr passed 800 metres in 1:51.1.
After the pacemakers withdrew, Kerr took control and reached 1,200 metres in 2:46.39. That left him to sustain the attempt alone through the part of the race where controlled pacing becomes a direct contest with fatigue.
Kerr passed 1,500 metres in 3:27.62, faster than his previous British record of 3:27.79 for that distance. The remaining 109.344 metres carried him across the finish in 3:42.66.
The splits show where the performance was built. Kerr did not depend on a wildly fast opening lap followed by survival. The pace remained close to the required schedule, and he preserved enough speed to complete the final section without giving back the margin created earlier.
Nuguse stayed within reach during the first part of the race but could not maintain Kerr's closing pace. The final gap confirms that Kerr was racing the clock rather than relying on a late tactical kick to win.
World Athletics Ratification Follows
The asterisk attached to early official reporting does not mean the timing is disputed. World Athletics uses pending-record notation while required procedures are completed.
Ratification normally depends on checks including certified timing, track compliance, competition documentation, doping control and applicable equipment rules. Until that process is finished, the accurate wording is that Kerr produced a pending world record or world-record performance.
The governing body's athlete profile already records 3:42.66 as WR(p). If ratified, the mark becomes the official standard future mile attempts must beat.
Kerr's 1,500-metre split may also require separate treatment because an intermediate time is not automatically processed identically to the finishing result. The mile performance is the central record established by the London race.
💭 TheTrendsWire's Take
The number 3:42.66 matters, but the larger achievement is that Kerr made a highly public record attempt behave like a controlled performance rather than a promotional stunt. Project 222 created a simple target. The race plan then translated it into exact work: pacemakers held the early schedule, Kerr took over before 1,200 metres, and his 1,500-metre split left enough margin for the final stretch. There is also a useful precision point. Kerr did not run the mile in 222 seconds or less. He ran 222.66 seconds. That was still fast enough to remove 0.47 seconds from a record that had stood since 1999. The remaining administrative step is ratification, not another race. If the mark clears the standard checks, future athletes will no longer chase El Guerrouj's 3:43.13. They will chase Kerr's 3:42.66.
