The calling for an average person to do the event right before the Olympians compete so we can appreciate how difficult the events are would certainly apply here.
Longtime swim/Olympics fans… I might be imagining this, don’t know the right terms to search for it on YouTube or Wikipedia… was there once an Olympic swimmer who figured out a backstroke loophole and did the entire first lap underwater? Launched off the blocks, did that dolphin-on-back thing down to the bottom of the pool and just kept going? I can’t figure out how to confirm/refute this, and it’s bugging me.
