17 seconds for 100m?
Yeah, I did that when I was around 28 years old.
Ohhhhh wait, you want me to do that 422 times in a row, without stopping!
or set the treadmill for 21kmh and maintain that for almost 2 hours.
won't be recognised by the IAAF though due to contrived conditions :-
* contrived track around the park which was levelled
* team of 41 pace setters helping him
* guided by a electronic car flashing a laser on the road for comparison
* and something to do with special enhanced shoes
pretty amazing though , think he has the World Record for 2 hours , 1 minute
