British middle-distance runner Josh Kerr broke the men's mile world record on Saturday, July 18, with a time of 3:42.66 [1].
The achievement ends a nearly three-decade era of dominance by Hicham El Guerrouj, whose record of 3:43.13 had stood since 1999 [2]. Kerr's performance marks one of the most significant milestones in modern athletics, proving that the long-standing barrier of the late 1990s could be breached.
Kerr achieved the feat during the London Diamond League meeting in the United Kingdom [3]. The event drew approximately 60,000 spectators [3], creating an atmosphere that commentators described as incredible.
The victory was the culmination of a deliberate strategy known as "Project 222." Kerr had publicly pledged to break the world record months earlier, specifically training for the attempt [4].
"I called it 'Project 222' back in March," Kerr said [5].
To prepare for the race, Kerr utilized specialized training methods including altitude rooms, and speed suits [4]. His successful bid in London confirms the effectiveness of this targeted approach to middle-distance running.
The crowd of 60,000 fans witnessed the moment Kerr crossed the finish line to secure the new mark [3]. The result establishes a new benchmark for the mile, shifting the global standard for the event for the first time in 27 years [1].
“Josh Kerr broke the men's mile world record on Saturday, July 18, with a time of 3:42.66.”
Kerr's record-breaking run signals a shift in middle-distance running where highly specialized, data-driven training regimens—such as those used in 'Project 222'—are successfully overcoming historical plateaus. By breaking a mark that had persisted for 27 years, Kerr has not only set a new athletic standard but has also demonstrated the potential for modern sports science to push human endurance beyond previous limits.
