Does anyone know if there is an "official" world best for 3 miles from the last 10-20 years? I know it was a commonly run distance up through the 70's, but can only find Ron Clarke's 12:52.4 as the last WR for the distance in 1965. He later ran a 12:50.4 split en route to his 5000m WR of 13:16.6 in 1966.
I'm guessing Kenny B went through 3 miles in his 12:37.35 at about 12:10. Does anyone know if there is an official split for this?
Thanks
