21. Katie Ledecky-2016 Summer Games
Katie Ledecky is the greatest female competitive swimmer in the world today, full stop. Don’t believe us? You should probably check out her complete domination at the 2016 Summer Olympic Games. It was here that she put on one of the greatest performances at the Olympic Games the world had ever seen. She could have competed in more events but decided to let other people win some medals and only competed in 5 of them.
Ledecky won 4 Gold Medals with 1 Silver happening in a team relay, which she brought the Americans back in to win. Katie already held several World Records from her time at the 2015 World Championships. When she made it to the Olympics, she set two more World Records for her times in the 400m freestyle & 800m freestyle. Both are still World Records today.
