If you like swimming, Katie Ledecky is fun to watch. She is on a whole different level than everyone else in the sport, similar to how Usain Bolt was. She is actually further ahead of the rest of the pack than Phelps ever was. The difference between Phelps and her is that she only dominates in 3 individual events, where as Phelps was able to pull out victories in 4 individual events. The races are also not as exciting because she wins them by so much lol. It’s still super impressive to watch.
