Don't feel bad. There are some real idiots on this site. They'll tell you you're stupid then not offer a bit of their apparently "stellar" knowledge.
They likely have mediocre talent or intelligence and they cry over it in their subconcious mind.. they need to tool with you. Never feel bad a moron calls you an idiot. You don't want to be a moron do you?! lol...
I know a few elite athletes, they are extremely efficient and derive so much happiness from sport. It is their life. They are living the dream. So the races are tough. I know one closesly and she blacks out from time to time. SHe has run on a toe that fractured minorly during a race. It's just the nearly divine love for the sport.
