Certainly not in the time frame you've described in the poll.
It involves every lap being run in under 45 seconds. That's a world class 400m time, when you consider that you start to see how impossible it would be. 43 seconds is a ridiculous amount of time to take off. It's not impossible, but I can't see it happening.
I reckon 2100 at the very earliest and that's with significant improvements in track conditions, shoes and training techniques in particular.
