Overview

• Faith Kipyegon, the three-time Olympic 1,500m champion and current world record holder at 4:07.64, must shave nearly eight seconds off her time to dip under four minutes.
• Nike’s Breaking4 project outfits her with a 3D-printed sports bra, aerodynamic skinsuit and ultra-light 85-gram spikes designed to reduce friction and wind resistance.
• A formation of male pacemakers and pacing lights will facilitate drafting but render any performance ineligible for official record ratification.
• The exhibition is livestreamed on Nike’s YouTube, Instagram and TikTok accounts as well as Amazon Prime Video as part of Nike’s bid to re-engage women runners.
• Forecasted favorable weather and Kipyegon’s strong history at Stade Charléty, where she set 1,500m and 5,000m world records, add momentum to today’s attempt.
