At the Olympics, dressage riders lead horses through complicated routines set to disco beats, 80s jams, classical and everything in between. The music is meant to highlight the horse's best qualities.

It's no accident that the track feels fast to runners. The Italian company that designed the track says its goal is to take "human speeds to levels never reached before."

"You're running against grown men, so you've got to do everything you can to beat them," Erriyon Knighton said. He's had a dramatic rise in track, beating a long-standing record set by Usain Bolt.

This event pitted the world record holder against the defending gold medalist. Sydney McLaughlin and Dalilah Muhammad are both U.S. athletes. Both beat the previous world record.

Biles looked happy and relieved after dismounting the balance beam, smiling and waving at the crowd to roaring applause. She's still experiencing the "twisties" but has found ways to cope.

Is she the best long jumper of all time? "I am," she says. "Point-blank." Reese doesn't hold the world record, but she's established herself as an extraordinary athlete over a huge number of years.

The world record was absolutely smashed with the fastest field ever to run the men's 400-meter hurdles. Norway's Karsten Warholm took gold and Rai Benjamin won bronze for the U.S.

The swimmers are now leaving Japan and the spotlight moves to the track and field events at Olympic Stadium. We'll walk you through the biggest things to watch for until the closing ceremony.

The 21-year-old from Arizona pulls off a complicated tumbling routine with a high degree of difficulty, earning her first Olympic medal.

The U.S. players had a 1-0 loss against Canada in the semifinal. They'll take bronze if they win their next game. The U.S. lost its star goalie to an injury in the first half.

"We are so excited to confirm that you will see two U.S. athletes in the balance beam final tomorrow - Suni Lee AND Simone Biles!!" USA Gymnastics said. Biles has withdrawn from other events.

Suddenly well behind the leaders, Dutch distance runner Sifan Hassan stood up and turned on the gas. Eleven of the world's fastest runners stood between her and victory.

Jacobs beat his personal best time and put his star solidly on the map in the blazing fast race. The U.S.'s Fred Kerley, who is 26 and from San Antonio, took silver.

Lee flipped and twisted from bar to bar in a sparkly blue leotard. She smiled and looked confident as she walked off the mat, and seemed a little surprised at her score.

Skinner was tapped to compete in the vault individual final after Simone Biles, the greatest gymnast in the world, withdrew from the competition to focus on her mental health.

Saunders said she's been open about her mental health struggles so others don't feel alone. It's also why she wears her identities so proudly as a gay Black woman.

"Simone has withdrawn from the event final for floor and will make a decision on beam later this week," USA Gymnastics said. "Either way, we're all behind you, Simone."

It's been an astonishingly successful Games for the 24-year-old from Florida. He added two gold medals to his haul from the Tokyo Olympics, departing the Games with five golds.

Elaine Thompson-Herah of Jamaica has won the fastest women's track race at the Tokyo Games in Olympic record time. She was the defending gold medalist in this event. Jamaica swept the final.

U.S. swimmer Katie Ledecky has won Olympic gold again in the 800-meter freestyle. She repeated her gold medal swim at the 2012 London and 2016 Rio de Janeiro Olympics to win at the Tokyo Olympics.
