Another major running world record has been smashed in London, and Brooks is at the center of the major moment. Josh Kerr ran the fastest men’s mile ever on Saturday, finishing in 3.42.66 at the IAAF Diamond League athletics competition.

The Scottish-born Kerr wore a custom spike and speed suit, created in collaboration with Brooks. The brand said the athlete’s Hyperion 222 shoe was designed for Kerr’s biomechanics, “including his unique foot strike, asymmetrical push-off and demand for an ultra-aggressive ride.”

The style’s name is derived from “Project 222,” the joint campaign between Brooks and the athlete in their quest to break the men’s record for the outdoor mile. (222 is the number of seconds that it took to beat the prior world record of 3:43.13, set by Morocco’s Hicham El Guerrouj in 1999.)

The shoe was developed using Brooks’ Run Research Lab and Finite Element Analysis (FEA) data.

Kerr, 28, also sported a speed suit that was “crafted to enhance aerodynamics and breathability, with laser cut perforations that release heat and humidity while enhancing mobility.”

Brooks continues to be one of the running market’s most dominant brands. It began 2026 with double-digit growth in the first quarter as demand remained strong across regions and channels. The company said it delivered its strongest quarter in brand history after a record-breaking 2025.

Kerr’s record came less than three months after Adidas athlete Sebastian Sawe broke the marathon world record in London, finishing the race in under 2 hours.

While the mile run isn’t included in Olympics competitions, it has been a major focus for many brands in the past few years. Kenyan runner Faith Kipyegon, 31, almost made history in Paris last summer in her attempt to run a mile in under 4 minutes. The Nike athlete barely missed the feat, though she broke her own world record, finishing in 4:06:91.
