Josh Kerr made history at the London Stadium by breaking the legendary mile world record, previously held by Hicham El Guerrouj for 27 years. Kerr's remarkable time of 3:42.66 not only dethroned El Guerrouj's mark but also solidified his status as a world champion and Olympic medallist.

In March, Kerr committed to breaking this prestigious record, embarking on what he called Project 222—a reference to the seconds needed to surpass El Guerrouj's 1999 effort. His rigorous training included:

• Ice baths lasting precisely three minutes and 42 seconds
• Utilizing an altitude room in his Albuquerque home
• Collaborating with experts in biomechanics and physiology to optimize his performance gear.

During the Wanda Diamond League event, Kerr felt confident as he approached the line, stating, "I knew I had it in the first 400 because my pacemakers did an incredible job." He emphasized that his focus was not on merely chasing the world record, but on creating conditions that made breaking it inevitable.

Despite skepticism from some, including Lord Coe, who questioned Kerr's racing frequency, he proved the doubters wrong. Lord Coe remarked, "I think this will have blown the wall away, he will go on to do incredible things."

Kerr also shattered his own British record in the 1500m with a split time of 3:27.62. Reflecting on his achievement, he expressed humility, acknowledging the giants of British athletics whose footsteps he follows.

The event also featured notable performances, including Mondo Duplantis, who withdrew from the men’s pole vault due to an adductor issue, and Keely Hodgkinson, who secured her first outdoor win of the season in the women’s 800m with a time of 1:56.21. Meanwhile, Oblique Seville, the world 100m champion, faced defeat against Kayinsola Ajayi, who set a national record of 9.84.
