Kipyegon Sets Mile World Record at 4:07.64

Faith Kipyegon set the women’s mile world record at the Herculis meeting in Monaco on 21 July 2023, clocking 4:07.64 to demolish a mark that had stood for four years.

Five barriers broken in a single race

On a hot and humid evening at the Stade Louis II, Kipyegon locked straight onto the wavelights set for world-record pace. Pacemakers carried her through 400 metres in 1:01.76 and 800 metres in 2:04.10, with Kipyegon’s own splits reading 62.6, 62.0 and 62.2 seconds for the first three laps.

At the bell she was already ahead of the lights and charged clear with a ferocious final circuit. She became the first woman ever to break the 4:12, 4:11, 4:10, 4:09 and 4:08 barriers — all in one fluid, devastating run.

A record that lifted an entire field

Kipyegon won by almost seven seconds, more than half the length of the home straight. Behind her, every single athlete in the race set a personal best. Ireland’s Ciara Mageean took second in a national record of 4:14.58, moving to fifth on the world all-time list, while Ethiopia’s Freweyni Hailu crossed in 4:14.79.

Laura Muir ran a British record 4:15.24, Jessica Hull broke the Oceanian and Australian record with 4:15.34, and Nikki Hiltz lowered the North American and US record to 4:16.35. The previous world record of 4:12.33, set by Sifan Hassan on the same track in 2019, was buried under a wave of rewriting.

A third record in fifty days

The mile crown completed an extraordinary sequence. In Florence on 2 June she became the first woman under 3:50 over 1500 metres, running 3:49.11. A week later in Paris she shattered the 5000 metres record. The Monaco mile gave her three world records inside 50 days.

“I really enjoyed the race. I came for that, I wanted to chase the world record,” Kipyegon told reporters afterwards. Her 2025 times — a 4:06.91 exhibition mile and a 1500 metres world record of 3:48.68 — have since pulled her standards even further from the rest.

No woman had done what Kipyegon did on that Monaco evening. She had taken the mile record and split it open, and in doing so had dragged an entire generation through the gap behind her.
