The post was meant to be more about getting up and trying again after falling. This could happen in almost any bike sport. Many times in X-Games BMX street final I've seen riders fall off their bikes in the first run (and even sometimes in the second round!) and just hand in the towel when there's still a great deal of time on the clock. I understand it's thought of as a 'getting a feel for the course' round, but you might as well use all the time you have while you're there.
