The Flash doesn't just run fast, he IS fast-- if he can stroke and kick fast, then of course he would swim fast. So if the Flash had to actually swim the swim part (as opposed to running over the water), he would still do it very quickly.

It is not just about being fast. Swiming is about FORM. He is not a swimmer. A fast guy with poor form will not be a fast swimmer.
