U.S. swimmer Katie Ledecky has cast a long shadow over her sport since dominating the pool at the 2016 Olympics in Rio. She won four gold medals and one silver, going a perfect 3-for-3 in the three different individual freestyle distances.
After Monday's 400m freestyle final, she will not pull off the same feat in Tokyo.
In one of the most hyped events of these Games, Australia's Ariarne Titmus took down Ledecky to win her first-ever gold medal. Titmus swam the best time of her career—3:56.69—which was a mere 0.23 seconds off of Ledecky's world record from the 2016 Games.
