What Men's and Women's Mile Records Does This Won't Hurt a Bit Cite?

On This Won't Hurt a Bit's Extreme Running episode, the hosts say the men's one-mile record stands at three minutes 43 seconds, 18 seconds faster than Roger Bannister's four-minute mile. The women's record stands at four minutes 12.57 seconds, run by Russian athlete Svetlana Masterkova in Zurich in 1996. They call that 48 seconds faster than Diane Leather's five-minute mile. Leather's record, they say, stood untouched for seven years, and women's records at the distance were not recognized until 1967. David Epstein, author of The Sports Gene, adds that once Bannister broke four minutes, runners who had stalled at the barrier followed him through it.
