I'm English and I'm fit as a butcher's dog.

I assumed the thread was in worship of me till I opened it.

I don't know the answer, but statistically, black athletes would be far more represented in track and field than the swimming pool. Not a question of eugenics, more an observation of bone to muscle linking in the same way as you could differentiate skin pigment or note that people from the India sub continent are more prone to type II diabetes.

The other variables are about access to sport. You rarely see people from deprived areas representing in equestrian sports. Look at professional footballers and professional rugby players. Footballers come from a larger cross section of demographic than either type of rugby. Real rugby has a large socioeconomic representation from A & B and league a large geographic one.

So even if someone pointed out the answer, I don't see any purpose as it doesn't tell us anything?
