Career Records for U.S. Stars

In addition to world and Olympic records, Simone Biles and Katie Ledecky added to their legendary resumes in 2024.

Biles dazzled in gymnastics, helping the U.S. win team all-around gold and securing three individual (two gold) medals. That hardware increased her career collection to seven gold, two silver and two bronze, and Biles became the most decorated American gymnast ever.

Ledecky, similarly, buoyed her name in the all-time book.

As she earned two golds, one silver and one bronze, Ledecky took control of the Olympic lead for golds (nine) by a female swimmer and is now tied with Australia's Emma McKeon for most total medals (14).

Additionally, no American woman in any Olympic sport—summer or winter—has captured more medals than Ledecky.

On the final day of the Paris Games, longtime U.S. star Diana Taurasi made history of her own. She became the first basketball player to amass six gold medals as Team USA survived a thriller with France.

The queen of 400m hurdles, Sydney McLaughlin-Levrone formally wore her crown following a brilliant run.

McLaughlin-Levrone posted a 50.37-second time in the final, besting her previous world record of 50.65 seconds—which she achieved at the Olympic Trials in June—in a runaway win for gold. U.S. teammate Anna Cockrell finished 1.5 seconds behind her for silver.

As a result, McLaughlin now owns the three fastest 400m times in history—with six of the 10 best, as well.

McLaughlin again contributed to the women's 4x400 relay team, securing a second gold in Paris and her fourth overall.
