Josh Kerr has done what few elite athletes dare to do: he has called his shot in public. The Scottish miler and Olympic champion has announced Project 222, a formal attempt to break Hicham El Guerrouj's mile world record — a mark of 3:43.13 set at the Rome Golden Gala in July 1999 — at the London Diamond League on 18 July 2026. The target time is 222 seconds, or 3:42 flat, which would require Kerr to lower his personal best by more than three seconds. He will make the attempt at what is expected to be a specially organised Emsley Carr Mile, on home soil in front of a capacity crowd at the London Stadium.
The project is a full collaboration with Kerr's long-time sponsor Brooks Running, who are investing considerable resource in the attempt. The American brand is developing a set of custom racing spikes engineered around Kerr's specific biomechanics, tested through months of refinement and feedback loops. Three prototype speed suits are also under construction, each designed to reduce aerodynamic drag whilst conforming to competition regulations. Brooks will also provide physiological support across the campaign, covering areas including sleep architecture, heat management, and fuelling strategy. The level of investment is comparable to some of the sub-two-hour marathon projects of recent years, albeit scaled for the unique demands of a sub-four-minute-mile attempt at world-record pace.
El Guerrouj's record is one of the most durable in athletics. It has stood for 27 years, surviving multiple generations of elite milers including Hicham's own era-defining rivals, the Moroccan golden age, and the explosive emergence of British and Norwegian middle-distance talent in the 2020s. The closest anyone has come in recent years was Jakob Ingebrigtsen, who ran 3:43.73 in Oslo in 2022. Kerr himself currently sits sixth on the all-time list with the 3:45.34 he produced at the 2024 Prefontaine Classic, a performance that demonstrated genuine sub-world-record capability under the right conditions. He argues, credibly, that the record is approachable in 2026, particularly given the rapid advances in footwear technology and the professionalisation of race engineering.
The strategic rationale for this summer is sound. There are no outdoor World Athletics Championships in 2026 — the biennial championship cycle means the major global meet will not return until 2027 — which gives Kerr the rare freedom to build an entire outdoor season around a single time trial rather than the tactical championship racing that has defined much of his career. The London Diamond League date provides a home crowd, a world-class track, and the prestige of the sport's premier circuit. Kerr has spoken openly about wanting to be remembered as the defining miler of his generation, and he understands that doing so requires attacking records, not merely winning races. The announcement has already drawn considerable interest from the athletics community, with pacing strategies, weather conditions, and track preparation likely to receive significant attention as July approaches.
The precedent set by projects such as Nike's Breaking2 and Ineos 1:59 has normalised the idea of structured world-record attempts as media and commercial events in their own right, and Project 222 follows a similar template. Whether Kerr can close the gap to El Guerrouj remains genuinely uncertain — the world record in the mile has a mystique that has defied even the most prepared athletes — but the conditions in 2026 may be as favourable as they have ever been. A British miler, a British crowd, a summer night in London: the stage, at least, is perfectly set.
