Sydney McLaughlin broke the 400-meter hurdles world record at the USA Track and Field Outdoor Championships for the third time in one year.

The Olympic winner ran a time of 51.41 seconds in Eugene, Oregon, breaking her personal mark of 51.46. Over the past 12 months, McLaughlin has generally lowered the record from 52.16.

McLaughlin, who planned to celebrate by devouring "some real stuff besides greens," like a cheeseburger or pancakes, 

said, "Every time I foot on the track, everything is possible." The goal is to stretch myself and test the limits.

McLaughlin will eventually transition to the flat 400m and try to beat that (37-year-old) world record, according to his legendary coach, Bob Kersee, 

according to NBC Sports analyst Ato Boldon. This might happen after McLaughlin finishes this season with a world title in three weeks. 

These worlds, which are also in Eugene, are what McLaughlin is currently concentrating on in an effort to complete her collection with a win.

Allyson Felix, who is quitting the sport, finished sixth in the 400-meter event on Saturday, ensuring her spot on her 10th and final world championships team. 

Talitha Diggs, whose Olympian mother took part in last national competition before Felix competed in her first national competition, won to qualify for the worlds in three weeks.

Michael Norman beat his own personal best for the year to win the men's 400-meter race in 43.56 seconds. Norman earned no individual medals 

between the world championships and the Olympics despite being the fastest 400-meter runner in the world during the most recent Olympic cycle. 

Unexpected runner-up Allison improved his personal record from 44.29 to 43.70.

Keni Harrison, who holds the world record in the 100-meter hurdles and won the silver medal in the Olympics, won the race in 12.35 seconds, 

beating off Puerto Rican Jasmine Camacho-Quinn to become this year's fastest woman. Harrison narrowly defeated Alaysha Johnson by a tenth. 

Evan Jager came in second and completed the required time to be eligible for the international squad.

Jager, 33, admitted to Lewis Johnson on NBC that "getting my body and my confidence back has been a really hard, long process." You declare, "I'm really proud of myself."

Sinclaire Johnson won the women's 1500-meter race in 4:03.29 to earn a spot on her maiden world team. She is accompanied by Olympic medalists Elle St. Pierre and Cory McGee.

Olympic silver medalist Chris Nilsen won the pole vault with a height clearance of 5.70 metres. Despite being scratched, 

Sam Kendricks is still qualified to compete at the championships because he is the reigning world champion.

Kara Winger won her ninth U.S. javelin title and qualified for her sixth international team by hitting the qualifying mark on her last throw in her last national tournament before retiring.

Maggie Malone, this year's greatest thrower in the world, fouled on each of her three attempts. 

She may still participate in the world championship, though, as one of only two American women who fits the qualification.
