Faith Kipyegon, a decorated middle-distance runner, has partnered with Nike in the 'Breaking4' initiative to become the first woman to run a mile in under four minutes. The attempt is scheduled to take place at Stade Charléty in Paris. This market resolves to 'Yes' if Kipyegon achieves a mile time under 4:00.00 before December 1, 2025, as verified by official race results from World Athletics or Nike's official announcements. Source
