I get that it's a quirk of the sport's history, but it's funny and dumb that swimming awards medals and records for being the fastest at a slower stroke. It's like if track meets would have a 100m sprint, a 100m skip, and a 100m run-backwards.
If I could change things in the world, I wouldn't eliminate the extraneous strokes in swimming, but I would include additional competitions in all the track distances: backwards running, handstand walk, and one-legged hopping.
