One of the things that's really been pleasing me is that there's not even one 'right' shape for one event - tall swimmers who win on power but also short swimmers who win on precision, and just this evening, big beefy hammer throwers of the traditional shape and much slimmer ones that have the technique sorted. I like the idea that being the shape I am doesn't mean I can only do certain sports, basically, even if I'm unlikely to take up any of them right now.
