Where is the line between what is possible in a mile race and what is not? At this point in evolution, it is impossible to run a 1 minute mile, but where in between 3:43 and 1 minute is the line between possibility and impossibility? I'm talking about where humans are now, not where they might be after evolution has carried us to new heights.
the human body has no limitations only the factors of age dicipline and the will to succeed will come into play in crucial moments as these
I think 3:30 will be broken some day but not now. A sub 3 probably impossible without some genetic mutation or some ultra PED. As far as where humans are now if you're looking for an exact guess? 3:39 and change.
Around 3:30.
Bannister said that in the 50s, and most people laughed. But I think he's right.
Popular mechanica did an article on this a fews years back. I think I remember that based on charts of progression, genetic enhancement, and drugs, their scientific panel concluded that a 3:25ish would be the max. I will try to find the article if it is archived.
