"The time is absolutely amazing, and the sport is getting faster and faster," .

"It was absolutely unreal to have my family in the stands," she said. "I have never had them together in one place. So this was for me so big. After Tokyo, not having anybody, this was like a redemption."

McLaughlin crossed the finish line well ahead of the second-place finisher, Femke Bol of the Netherlands. In third was defending world champion Dalilah Muhammad, the U.S. silver medalist at the Tokyo Games and a previous world record holder in this event.

Noah Lyles breaks Michael Johnson's U.S. record

Lyles, 25, with 18-year-old phenom Erriyon Knighton in the 200 meters, but his real opponent was in the commentary box: Michael Johnson, who set the U.S. record of 19.32 in 1996.

Lyles finished so far ahead of the pack in the final that after crossing the finish line, he turned to stare at the clock 鈥� which initially said he had tied Johnson. When the official time of 19.31 was posted, Lyles, his family and the stadium celebrated deliriously.

A special moment then followed, when Johnson 鈥� on hand as part of the BBC's coverage 鈥� came down to personally congratulate Lyles. The record was set in the summer before Lyles was born.

Allyson Felix ends her worlds career with a record 20 medals

Felix, 36, was already the U.S. track and field athlete when she announced she would retire after the 2022 season. She's also won more world championships medals, and more gold, than any other athlete.

Her 19th medal, a bronze, came in the mixed 4x400-meter team relay. And that seemed to be all for Felix, who left Eugene. But she later flew back, after her coaches called Felix (who was by then enjoying ) to ask if she could help the women's 4x400 team get to the final.

She turned in a strong run in the preliminary round, putting the team into Sunday's final 鈥� which a different lineup then dominated, earning Felix her 14th gold and 20th medal overall.
