Lol. So what's next, 12:45???
C'mon. I'm not sayng you are wrong, but....
When Woody Kincaid [ who didn't break 14:00 til his Jr year in college??] runs 12:51 with a MONSTER kick, i.e. running as well as Bekele, Geb, and Komen ever did indoors [ or virtually equal] and the "best is still yet to come".... something is indeed "up".
It's either [ take your pick, or some combo of]-
1] the super shoes
2] the super track
3] PED's
4] "new age" methods [ artificial altitude air inhalation, gray area supplements, etc]
It's not just natural development/ hard work.
And I personally am certainly not saying it's number three. But it IS some combo of the above.
