HAHAHA Asians don't make very good runners either, you can't seperate based on race, face it the africans will always be better at running, for one they don't drive places as often and arent used to the fatass american lifestyle.
But hey who really cares right, I mean yeah there are all white sports like hockey (there are black guys in the NHL but not many) but then theres basketball which is predominately black guys, then theres volleyball which is mostly chicks. Some people have natural talent that probably relates to thier ethnicity in some small way, it's not racist its just a stereotype that is generally accurate.
