The stage is set for Josh Kerr's World Record Mile Attempt on Saturday, which has been labeled Project 222 by Kerr and his team.

This week fields have been officially announced for the 2026 London Diamond League meeting, providing even more insight into the nuances of the record attempt at-large.

Further, Brooks has revealed information and imagery about the gear that is powering Kerr's attempt. We broke that down last week - but a few highlights are the ultra-aggressive Hyperion 222 special fitted to Kerr's foot, and the speed-suit specifically designed to improve cooling in key areas.

US Audiences can watch Josh Kerr's World Record Attempt LIVE on FloTrack on Saturday, July 18 at 10:36 AM ET.

• The Gear Powering Josh Kerr's World Record Attempt

To break the World Record; Kerr (or anyone else for that matter) will need to run faster than the 3:43.13, set by Hicham El Guerrouj in 1999.

When considering the conditions, they'll be near perfect for Kerr and Co. The race is scheduled for 3:36 PM local time (10:36 AM ET) and weather forecasts are currently calling for a high of 74-degrees fahrenheit, 50% humidity and winds ranging up to seven mph. Historical data suggests that conditions may have been similar on July 7, 1999 - when El Geurrouj set his world record in Rome.

Entering the weekend, Kerr's personal record is the 3:45.34 that he posted to best Jakob Ingebrigtsen and Yared Nuguse at the 2024 Pre Classic. That time currently ranks Kerr sixth on the All-Time list. He'd go on to earn Silver in the 1500m at the Paris Olympic Games, his second Olympic medal in as many cycles. He, will need to shave over two seconds off of his time to hit the goal'ed 3:42 split.

The field itself, promises talent that could play upset to Kerr and his attempt.

Take for example Yared Nuguse. 

The Olympic Bronze Medalist, and former Indoor World Record Miler, has run 3:43.97, just nine-tenths off of the World Mark. In 2023, Nuguse sat on Jakob Ingebrigtsen's World Record Attempt at the Pre Classic. He ultimately finishing second to Ingebrigtsen, but the two ran the World No. 3 All-Time and World No. 4 All-Time marks, respectively. 

Nuguse has been on a tear this Diamond League season - with wins in the 1500m in Rabat and Stockholm and accompanying runner-up mile finishes in Oslo and Eugene. He ran a season best of 3:46.61 at the Pre Classic last weekend. 

That being said, he may be over-raced for a World Record Opportunity.

Kerr enters with much fresher legs, having run only two 800m races since May.

There Are Other Potential Suitors For The World Record Mile

Hobbs Kessler will be a sneaky pick on Saturday. This year, Kessler set the Indoor 2K World Record as he ran 4:48.79 to win the NB Indoor Grand Prix. For context, he split 3:53.04 through 1600m in that race. He has a personal best of 3:46.9 over the mile distance and finished fifth at the 2024 Paris Olympic Games (1500m).

How about Simeon Birnbaum in his Diamond League debut? Birnbaum was originally scheduled to race the Bowerman Mile at the Pre Classic but was a scratch due to illness. His historic NCAA season make him an interesting name to consider on Saturday. At just 21 years of age Birnbaum ran 3:31.69 to set the NCAA 1500m Record. That 1500m will roughly convert to a 3:48.63 Mile. He went on to win the NCAA Title.

Ethan Strand has to be high on your list as well. He just ran a 3:46.97, to run a US No. 3 All-Time Mark (Outdoor Mile) and finish third at the Pre Classic. Last year he ran 3:30.25 to finish second at the US Outdoor Championships in the 1500m.

Robert Farken is another dark horse - but we can't forget his sixth place finish at the 2025 World Outdoor Championships, or his 3:47.76 Mile Effort at this year's Pre Classic.

The Splits To Hit

To break El Guerrouj's record, the field will need to average 55.78 seconds per lap. During Kerr's personal best run at the 2024 Pre Classic, he hit average laps of 56.335, for his final time of 3:45.34.

Hicham El Guerrouj WR Splits:

• First Lap - 55.07
• Second Lap - 56.51 (1:51.58)
• Third Lap - 56.33 (2:47.91)
• Final Lap - 55.22 (3:43.13)

Project 222 WR Splits Needed

• First Lap - 55.50
• Second Lap - 55.50 (1:51.00)
• Third Lap - 55.50 (2:46.50)
• Final Lap - 55.50 (3:42.00)
