Alanbikehouston, ever heard of Darwin? While race may be a social construct, there are still societies of people that have evolved in one geographic region over the past few thousand years. For that reason, those people may have adapted special physical features and attributes that help them excel in certain sports. Your argument about humans all belonging to one race, fails to take into account that human beings from different parts of the world have evolved differently. While our genes may be 99.8% the same, people share different skills and attributes. Humans also share 98% of our genes with chimpanzees, but that doesn't make us the same.

You seem to have a problem with our culture and you're preaching about it in a bike forum. Everyone on this thread, I would venture, was taught in school about different races of people. They still ask you your race on standardized tests, insurance forms, etc. The concept of multiple races is ingrained in our culture. Now, I'm not arguing whether that's right, quite the contrary, I just believe arguing about the fallacy of our social constructs in a bike forum is fruitless.
