Overview

  • Faith Kipyegon will attempt an unofficial sub-four-minute mile at Stade Charléty in Paris on June 26, aided by Nike’s specialized footwear, skinsuit and male pacemakers.
  • Nike has doubled its investment in women’s biomechanics research, yielding aerodynamic apparel, 85-gram super-spikes and a prototype 3D-printed sports bra for the run.
  • The Breaking4 initiative is designed to showcase Nike’s technical innovations and recapture women runners who have drifted to rival brands.
  • Computer-guided pacemakers and pacing lights will optimize drafting to help Kipyegon shave over seven seconds off her 4:07.64 mile record.
  • Any time she records will remain unofficial under pacemaking rules; a February study suggests optimal drafting could produce a 3:59.37 finish.
