Agreed. And they don't even consider the other angle, which is do rich people love endurance sports more than other sports? That is, of the rich people who participate in sports, how many are in endurance sports versus those in other sports?
True. I used to race cars. The same logic applies there - you have to have money and free weekends to race cars. Even better if you have flexible work hours so you can practice on Fridays (before weekend events) and fix the car in the evenings (because they break, wear out, and get crashed).
