The Olympic Games are TIMED for a reason.
No matter how incredibly difficult each sport is, just being able to do it is not enough for Olympic excellence. In fact, all competitors illustrate phenomenal skill in their respective sports. But they are there to WIN. To do what they need to do in the shortest amount of time. This makes the genuine value of the skill greater not by accomplishment, but by accomplishment with speed. Basically, we don’t care how good you are if you’re slow at it.
