Watching BMX now. I accept it's skilled, exciting, dangerous etc etc, but it still looks like grown men on their kid's chopper bike. Cannot take it seriously (unless GB get a medal).
It works now. A few pages back a few people mentioned the theory that black Caribbean, US and British runners are so successful due it biologically being the strongest and fittest who survived the 'middle passage' of the slave trade and passed on their genetics, interestingly in the BBC coverage of the athletics, they just mentioned that theory as part of a mini-documentary (whatever you wanna call it).
A good point has just been made that if you live in a country with sprinters as heroes (i.e. Jamaica) you are more likely to want to be a sprinter. The more people that try a sport the more likely you are to find a star. Not said but presumably in GB lots of people want to be rowers and cyclists.
Vallegro, the horse that took gold in dressage, is up for sale with 2 others for 20 million. Must be heartbreaking to have your horse sold from under you and have to start with a new horse again.
It's no coincidence that Saudi Arabia won a medal in show jumping. The Irish guy who won bronze recently sold his horse to them.
That's very much the situation I think, just like in South Korea archery is the national sport so people growing up are more likely to want to become an archer, hence their success in archery.
