9.55

That’s how fast a group of physicists have calculated Usain Bolt would have run in the recent Olympic 100-meter final had he not started celebrating and thumping his chest with 20 meters to go (he still ran 9.69, a new world record).

I don’t know about that, there are a lot of assumptions there as the article points out, but if he really would have ran 9.55 I’d bet that would surely eclipse the longevity of Bob Beamons’ 29 ft. 2.5 inch mark in the long jump which stood from 1968 to 1991.

Bottom line, whatever it is that you’re doing, people, run through the tape. Always, run through the tape.
