I came across this article about "What actually makes a pool fast?" which I found very interesting given the upcoming Rio Olympics.
During swim competition, I had heard TV commentators, analysts, and swimmers say “This is a fast pool,”
but I always thought it was hyperbole so I never took it seriously. To my surprise, there are factors that can make a swimming pool “fast.”
I knew about water temperature, but water depth; gutter design; and lane width were factors that were revelations to me. I was also surprised to learn that there is NO standard competition swimming pool lane width.
