I ran track in high school, high hurdles and the 440 (this was before the metric system took over in track) and trained with the high jumpers. At the county championship all the jumpers were straddling except for the winner who was doing the Fosbury Flop, he won easily and went on to become an NCAA champion at U of Oregon. It was the first time I'd seen the flop live and it blew my mind, to use the parlance of the day.
