I actually have one main question and that concerns the hurdle heights. Are the heights measured metrically or imperially in official IAAF competition, and, if not, why not?
Also, when was the last time that someone has been as dominant as Sanchez in the 400h without coming close to running sub-47, much less barely near the sub 48 mark?
