How many here are sprinters and how many long distance swimmers?

I've always been lead to understand that we are all born with either fast twitch/white muscle fiber or slow twitch/red muscle fiber. That being said, sprinters can generate explosive bursts of speed that are limited to the short distance events. Whereas the distance swimmers can maintain a race pace for over half an hour before they finally wear out. It's usually a rare occasion to see a swimmer cross over from sprint events to long distance and vice versa. But putting sports physiology aside,...spartan like training can bring about phenomenal performances irregardless of the fiber theory. For example, an exception to the rule would be Tom Dolan,.. a virtual animal in the water. His five hundred yard record stands untouched. And the splits were broken down with a 47 on the first hundred and 49 and change for the following four. His fifty time was also one of the fastest ever recorded at 19 plus. Here's a unique case of someone excelling at both sprinting and distance swims. P.S. Peter...you are an animal. 1650 fly!!!!!????
