So many sports are entirely about the physique you inherited though. Yes there is some technique to swimming and obviously you have to train hard. But these are just prerequisites, not differentiators. If we start saying that winning because of your physique is no victory, then really half of the events become meaningless. To a large extent, the Olympics does measure inherited traits and I think we ought to recognize that that is its point. If you think back all those centuries, it was very obviously the point to prove that your people are genetically superior to their people.
