(NEW YORK) — American Katie Ledecky is looking to further cement her name in swim history with a race making its Olympic debut in Tokyo.

The 1,500-meter freestyle had previously only been available to men at the Olympics. But this year, as the Games became more gender-equal, the distance race was opened up to women.

Ledecky is a favorite to win the race. During qualifiers Monday, she set the official Olympic record at 15:35:35. That was about 15 seconds slower than the world record — which she set in 2018.

The 24-year-old has already medaled once in Tokyo, winning the silver in the 400-meter freestyle. Australian Ariarne Titmus took home that gold.

“I can’t be disappointed with that,” Ledecky said of that race, according to Team USA. “It was my second best swim ever, and I fought tooth and nail. That’s all you can ask for.”

As a distance freestyle swimmer, her bigger events are the 800- and 1,500-meter races.

The heavily decorated Olympian won one gold in 2012 and four golds and one silver in 2016 at the Games. In addition to the 1,500 and 400, she’ll look to add to her count with the 200-meter and 800-meter freestyle races.

The Olympics have made the competition more gender-equal by incorporating new events for women and more mixed-gender teams in various sports. This impacts athletes in sports like boxing, rowing and shooting, in addition to swim.

Tokyo marks a “turning point” for the elite international sporting competition as the most gender-equal Olympics in the Games’ history, organizers said, with women accounting for nearly 49% of the 11,090 athletes.
