British middle-distance runners Keely Hodgkinson and Josh Kerr are preparing to challenge longstanding world records at next month’s London Diamond League, aiming to create a historic moment for UK athletics outside of a major championship setting.

Hodgkinson, who holds the indoor 800m world record set earlier this year, has her sights set on the outdoor 800m record—a mark that has stood unbeaten for 43 years. The current record of 1:53.28 was set by Jarmila Kratochvílová in an era often associated with performance-enhancing drug controversies. Hodgkinson, an Olympic gold medalist and three-time global silver medalist, has approached this goal with measured confidence, recognizing the magnitude of her challenge but undeterred by it.

In recent weeks, the 800m field has intensified, with Swiss athlete Audrey Werro emerging as a formidable contender. Werro, who has typically finished just behind Hodgkinson in previous competitions, defeated the British champion in her first 800m race of the season two weeks ago, posting the fastest global time since the 1980s. Both athletes are expected to compete in separate Diamond League events prior to the London meet, where they may each have an opportunity to break the existing record. Hodgkinson acknowledged Werro’s competitiveness and the motivation it provides, signaling a renewed rivalry as the season intensifies.

Meanwhile, Kerr is targeting the mile world record at the same London fixture, aiming to beat Hicham El Guerrouj’s 27-year-old mark of 3:43.13. The 2022 1,500m world champion has maintained a singular focus on this goal throughout the season. Uniquely, he has not raced over the mile or 1,500m distances in 2026, including opting out of the UK Athletics Championships this weekend, deeming such events distractions from his singular target. Kerr’s commitment is underscored by his consistent mental and physical preparation routines—such as daily journaling of his desired record time and timing his ice baths to match the target record performance in seconds.

At the UK Championships held at Birmingham’s Alexander Stadium, Hodgkinson competed in the 400m, describing the race more as a training exercise than a competitive event. She has logged only one 800m race this season, a defeat to Werro that has added a layer of intrigue to her upcoming record attempt.

British athletics history features relatively few world records dating to beyond the early 1990s, with Jonathan Edwards’s 1995 triple jump and Hodgkinson’s recent indoor 800m mark among the rare highlights. In this context, the London Diamond League promises a potentially landmark afternoon, as two of the nation’s premier middle-distance runners strive to eclipse records that have stood for decades, providing a significant focus in a season absent of Olympic or World Championship events.
