Overview
- Kerr ran a 3:42.66 mile to break the long‑standing 1999 record, a performance that Project 222 targeted and accomplished on July 18 in London.
- He wore a one‑of‑a‑kind Brooks Hyperion 222 spike built with a tuned carbon‑plate system and an upper shaped to his foot and racing rhythm.
- Brooks says the Hyperion 222 is not for sale but it informed the company’s consumer Hyperion line, including the Hyperion Elite 6 and the Glycerin 23, which are being promoted and sold at current discounts.
- World Athletics formally granted Kerr an exceptional invitation to the World Athletics Ultimate Championship in Budapest from Sept. 11–13 and he will face Jakob Ingebrigtsen in the 1,500m field.
- The record run ties elite performance to product development and marketing, a dynamic that could lift Brooks’ sales and reshape middle‑distance rivalries as athletes and organizers weigh custom race spikes versus consumer models.
