Josh Kerr will chase athletics history when he lines up in the London Diamond League on 21 July, with a world record attempt on the line in the men’s 1500 metres.
What’s happening in London?
The Diamond League meeting at the London Stadium will feature a stacked 1500m field, headlined by Kerr’s bid to smash the world record of 3:26.00 set by Hicham El Guerrouj in 1998. World Athletics has rubber-stamped the attempt, meaning the track is set for a potential record-breaking night in the British capital.
Kerr, the reigning world 1500m champion, arrives fresh off his victory at the 2025 World Championships in Tokyo. His time of 3:27.67 in Japan underlined his status as the man to beat over the metric mile. Now he turns his focus to London, where organisers have framed the meet as a “world record night” if conditions align.
Why this attempt matters for Kerr
A sub-3:26 clocking would erase El Guerrouj’s 26-year-old mark and cement Kerr’s name alongside legends like David Rudisha and Usain Bolt. The Scotsman has already run 3:28.69 this season, quicker than anyone else in 2026, but the record remains tantalisingly out of reach.
Kerr’s coach, Andy Young, said the squad is treating the attempt as a “high-risk, high-reward” project. “We’re not banking on perfect conditions, but we’ll push as hard as we can,” Young told reporters. The team will rely on pacemakers to chase the world record splits, with Kerr expected to kick clear in the final 400m if the pace holds.
Who else is in the field?
The 1500m line-up reads like a who’s who of middle-distance running. Norway’s Jakob Ingebrigtsen, the 2024 Olympic champion, headlines the opposition, while Kenya’s Emmanuel Wanyonyi — the 2025 world indoor champion — adds firepower. Ethiopia’s Samuel Tefera, the 2023 world indoor winner, rounds out the trio of sub-3:30 milers chasing glory.
Ingebrigtsen, who ran 3:27.14 in June, has already set his sights on London. “I want to race Kerr at his best,” he said. “If he goes after the record, I’ll do everything to help him — or beat him.” Wanyonyi, meanwhile, arrives off a 3:29.50 personal best in May and could play the role of pacemaker if the pace drops early.
What happens next?
The London Stadium will host the showdown on 21 July, with the 1500m final scheduled for 20:45 BST. Weather forecasts suggest mild conditions and a light breeze, factors that could swing the attempt either way. World Athletics will deploy its standard timing protocols, including laser splits every 100m to track Kerr’s progress against the record.
Kerr’s agent, Mark Butler, confirmed the attempt is “all systems go” barring unforeseen issues. “Josh’s training has been flawless,” Butler said. “He’s ready to chase greatness.” If the record falls, the IAAF will recognise it immediately, adding another chapter to track and field’s most storied record book.
