Who is the fastest person who is famous for something else?

Malcolm Gladwell was an accomplished 1500m runner in his earlier years.

I heard him speak once, and he mentioned in passing that at one time he was the #3 1500m runner in Canada, but he said nothing of times, and it is hard to find anything on that.

His running was a topic a few months back, but it quickly disintegrated into an argument over his theories.
