Scientific American talks with movement researcher E. Paul Zehr on his book Becoming Batman: The Possibility of a Superhero:

There’s a quote from Neal Adams, the great Batman illustrator, who said Batman would win place or show in every event in the Olympics. Probably if I were Batman’s handler, I’d put him in the decathlon. Although Batman is shown in the comics as being the fastest and the strongest and all these other things, in reality you can’t actually be all of that at once.

And yes, I ordered the book.
