Katie Ledecky already has seven Olympic gold medals in swimming. But she's not done yet.

Ledecky, 27, could become the most decorated female Olympic swimmer of all time at the 2024 Paris Games as she competes in four different events: the 400-, 800- and 1,500-meter freestyle, and the 4x200 freestyle relay. With a total of 10 Olympic medals in the pool, Ledecky is just two behind the record held by Jenny Thompson, Dara Torres and Natalie Coughlin.

And if she can win three of those events, she'll break former Soviet gymnast Larisa Latynina's overall women's record of nine Olympic golds.

First up is the women's 400-meter freestyle.
