Eyes wide, teeth bared, Faith Kipyegon pounded down the home straight.

The crowd screamed encouragement as she crossed the finish line at Paris’ Charléty Stadium and collapsed on the track, overcome by lactic acid and exhaustion.

The time on the clock read 4:06.42. The Kenyan runner had just run the mile faster than any woman in history.

Yet standing trackside at that moment, the atmosphere in the stadium was weird. It was like the 2000-strong crowd didn’t know quite how to feel.
