Edited to add: From a post on a triathlon forum -
socially, distance runners never get the girl. Girls like the ones who can stay and fight, not the ones who can get away the fastest. Distance runners have muscles -- very well-developed muscles. But they are long and thin, not short and thick. The best are featherweights. Look at the guys who are at the front of the marathon pack. They have all the bulk of the javelins that the really strong guys toss a couple hundred feet.
