In-Depth Analysis
The Science Behind 'Project 222'
Josh Kerr's world record attempt is the culmination of eight months of intense preparation, cutting-edge sports science, and unprecedented collaboration with sponsor Brooks. The 28-year-old is using a rare year without a global championship to focus entirely on one goal: running a mile in 3 minutes and 42 seconds.
Bespoke Spike Technology
The Hyperion 222 spike was built from the ground up specifically for Kerr's biomechanics. Unlike off-the-shelf models, this one-of-a-kind shoe features:
Minimal foam in the heel with aggressive taper to the toes, acting as a rocker to propel Kerr forward
A carbon-fiber plate providing "maximum stiffness"
Titanium pins not available on the mass market
Custom fit for Kerr's size (6ft 2in), accommodating his greater force and energy return potential
Danny Orr, Brooks' senior director of product development, said the spike "breaks all previous design moulds" and represents "stage one" of what the company aims to achieve by the 2028 Los Angeles Olympics.
Speed Suit and Aerodynamics
Kerr will also wear a bespoke speed suit made from two fabrics with laser-cut holes, minimal seams, and moisture-wicking panels. Multiple versions were crafted due to London's unpredictable summer weather, all tested in wind tunnels for aerodynamic gains.
Training and Physiology
Coach Danny Mackey simplified Kerr's preparation by focusing on target pace rather than tactical variability. Key training elements include:
Altitude training: in Albuquerque, New Mexico
800m races: at PB pace (1:44.60) to develop raw speed
Specific sessions: like 4x (200m + 600m + 200m) at world-record pace
70 miles per week: of mileage with strength and 1500m work
Brad Wilkins, a physiology expert who has worked on similar projects (Nike's Breaking2), identifies three critical factors for a world-record mile:
Big anaerobic capacity - energy production without oxygen
High VO2 max - maximum oxygen uptake during exercise
Motor unit recruitment - maximizing muscle fiber activation
The Race Setup
Kerr wanted London for the attempt despite coach Mackey's preference for Monaco or Carolina due to more reliable weather. The field has been kept small to avoid the kind of fall that disrupted last year's 1500m. Pacemakers Brandon Kidder (Brooks Beats teammate) and Zan Rudolf will lead the charge, with Yared Nuguse (American record holder, 3:43-something) expected to push Kerr to the line.
Other Major Events at London Diamond League
The event is packed with world-class competition across multiple disciplines:
Men's Pole Vault: Armand Duplantis returns to the London Stadium for the first time since 2019, where he finished ninth as a 17-year-old. He recently suffered a rare defeat in Stockholm but bounced back in Paris.
Women's 200m: Julien Alfred (meeting record 21.51 in Monaco) vs. Gabrielle Thomas and British stars Dina Asher-Smith and Amy Hunt.
Men's 800m: Olympic champion Emmanuel Wanyonyi vs. Canadian world champion Marco Arop and British record hopefuls Ben Pattison and Max Burgin.
Men's 100m: World champion Oblique Seville, Letsile Tebogo, and Britain's Zharnel Hughes.
Women's 3000m: Deep field including Jessica Hull, Laura Muir, and Medina Eisa.
FAQs
When and where is the London Diamond League 2026?
The event takes place on Saturday, July 18, 2026, at the London Stadium (Olympic Stadium) in London, UK, starting at approximately 13:00 BST.
How can I watch the London Diamond League?
In the UK, coverage is live on BBC One, BBC iPlayer, and the BBC Sport website. In the US and internationally, it streams live on FloTrack and the FloSports app.
What is Josh Kerr's goal time for the mile world record?
Kerr is targeting a time of 3:42 (222 seconds), which would break Hicham El Guerrouj's 1999 world record of 3:43.13.
Who is in the men's mile field?
The field includes Josh Kerr (GBR), Yared Nuguse (USA), Hobbs Kessler (USA), Neil Gourley (GBR), and pacemakers Brandon Kidder (USA) and Žan Rudolf (SLO), among others.
What other British athletes are competing?
Keely Hodgkinson (women's 800m), Zharnel Hughes, Romell Glave, Jeremiah Azu (men's 100m), Matthew Hudson-Smith (men's 400m), Dina Asher-Smith, Amy Hunt (women's 200m), Laura Muir (women's 3000m), and Ben Pattison, Max Burgin (men's 800m).
Is the men's mile world record considered beatable?
Experts believe Kerr has a strong chance. His 800m PB (1:44.60) demonstrates the necessary speed, and his training has been specifically tailored to hold 55.5-second 400m laps. The presence of Yared Nuguse provides crucial competition to push the pace.
Key Takeaways
For Athletics Fans: This is a historic moment. The men's mile world record hasn't fallen since 1999. Watching Kerr's attempt live could mean witnessing a once-in-a-generation achievement.\n- **For Aspiring Athletes**: Kerr's preparation shows the importance of specialized training, technology partnerships, and mental confidence. His approach of simplifying preparation by focusing on a single target pace is a masterclass in goal-setting.\n- **How to Prepare to Watch**: Set a reminder for the men's mile (approximately 15:36 BST / 10:36 AM ET). The full schedule is available on BBC Sport and FloTrack.\n- **Who This Affects Most**: Middle-distance runners, coaches, and sports scientists will be closely watching the technology and methods used, as they could influence training approaches for years to come.\n- **Historical Context**: Only four men have ever run a sub-3:44 mile. A Kerr record would place him alongside legends like El Guerrouj, Ngeny, and Ingebrigtsen in the sport's history books.
