Don't get me wrong, I am not saying I have the ability to do so, just that I am not required to pay someone to be certified.
Gebreselassie is a great example...he was the greatest middle distance runner (e.g., 10 km), but was not a marathon runner. He was paid to run the London marathon, as his first serious marathon. As I recall, he had only one 1 marathon before, as 15 year kid for fun, and ran 2:45. He proceeded to run at London the 3rd fastest marathon time ever! I think the analagy would be he was not a "certified" MARATHON runner (since there is no certification), but still ran the 3rd fastest time ever. Do we need an organisation to say "you're certified - you can enter this tournament"?
