re: Hardest feat to acomplish in sports?

That's even more evidence for it not being like the mile barrier.

Two guys owning the record for 50 years.

Unlike the mile where the floodgates opened.

I still believe it will happen but it probably won't.

You have to make up 8 inches...

Well the world record progression for half a century went by 1 or 2 inches.

Then we got drugs...in the 70's...



But even that flattened out.

The first WR in the long jump was 1901.

It was 25 feet.

100 years later...the WR was 29 feet, 4 inches.

100 years...4 feet.

As the previous poster said maybe even with PEDs humans still can't do it.
