Kipyegon surpassed her own world record of 4:07.64, set two years ago, but fell well short of breaking the 4-minute mile.

Faith Kipyegon ran a mile in 4 minutes, 6.42 seconds — more than a second faster than her world record — at "Breaking4," a special event billed as Kipyegon's attempt to become the first woman to run a mile in under four minutes.

The 31-year-old Kipyegon is the owner of three Olympic gold medals and the women's world record time in the mile.
