Hicham El Guerrouj's mile world record is in jeopardy as Josh Kerr prepares to attempt to break it on July 18.
What's at stake?
Kerr's chance to clear Guerrouj's 1999 Rome Golden Gala record will be his toughest test yet.
The challenge
Yared Nuguse's addition to the lineup changes the dynamic, with the American having a faster personal best in the mile.
Kerr's fastest time in the mile is 3:45.34, set at the Prefontaine Classic.
Nuguse competed at the Bowerman Mile during the Eugene DL, where he was shockingly beaten by Cameron Myers.
## What comes next?
Nuguse now looks to the London DL, where he will face Kerr and potentially threaten his record attempt.
The British runner has spoken about what Project 222 means to him, embracing pressure and putting himself out there.
But now, Yared Nuguse stands in his way, having won both his 1500m races in the DL.
Nuguse's first win came at the Rabat DL, where he won in 3:30.35, and his second win came during the Stockholm DL.
Kerr has been selective with his schedule, last competing in mid-June at the USATF LA Grand Prix.
The Brit has never shied away from the challenge, insisting that breaking El Guerrouj's record requires the best in the world on the start line.
On July 18, Kerr will have his chance to make history and break Hicham El Guerrouj's record.
The world record stands at 3:43.13, set by Hicham El Guerrouj in 1999.
Kerr's current personal best is only good enough for sixth place, while Nuguse and Jakob Ingebrigtsen sit higher in the rankings.
The 2026 London Diamond League will be the stage for this epic battle, with the world watching to see if Kerr can break Hicham El Guerrouj's record.
The event will take place on July 18, and the world will be waiting to see the outcome.
Josh Kerr announced in late April that he would attempt to clear Guerrouj's record, and now the stage is set for an exciting showdown.
The question on everyone's mind is: can Kerr break Hicham El Guerrouj's record, or will Nuguse spoil his plans?
