The four-minute mile was a fact about the limits of the human body until May of 1954. Landy then took Bannister's record off him that June, and by August the two of them ran under four minutes in the same race in Vancouver. Nothing about human anatomy changed that summer. What changed is that the frontier stopped being a rumor and became a place you stand on; once that happened, everyone who waited for it to resolve arrived to find it already priced into the new normal.
Bannister and Landy stepped onto an exponential the moment the barrier fell, and we are on one now. When you are on an exponential, a step back from the edge is not the careful position: it is the expensive one. Living on the miracle mile is genuinely unpleasant, and it does not get less unpleasant with practice. What you design is superseded before you finish building it, and you are wrong in public about as often as you are early. Discomfort is not the price of standing on the frontier. It's the only reliable evidence that you are where you should be.
Nobody runs a fast mile with their form intact through the last quarter. The only rule is that you keep running at the edge of what you can hold: go out hard, come up for air, or decide the barrier was never real.
