Plus the coaching merry-go-round among the top US women's 1500 runners this year and thoughts on the NBC broadcast, which disappointed.

For the first time in 32 years, two outdoor women's distance world records on the track fell on the same day. Chebet is the first woman under 14:00 for 5000m on the track while Kipyegon broke the 1500 record for the third time.

An American man hasn't held the mile world record in over 50 years. Might that change on Saturday in Eugene?  Nuguse's coach Dathan Ritzenhein: "It won’t shock me if they break [the world record]."

• An American man hasn't held the mile WR in 50+ years, might that change at the 50th Pre? Ritz: "It won’t shock me."
• Pre Classic - Will Grant Fisher finish DFL in Bowerman mile?

5000 WR holder Gudaf Tsegay wanted to add the 10,000 WR to her CV and she led for nearly 22 laps but then two-time World XC champ Beatrice Chebet took over and made history.

• Beatrice CHEBET drop PR From 33:29 to 28:54 WR ???

With just four weeks to go until the Olympic Trials, America and the world's best will descend on Eugene this weekend.

This weekend's Prefontaine Classic marks 10 years since Jonathan Gault's first meet for LetsRun.com. He reflects on what he learned from his first trip to Eugene to cover David Rudisha and Galen Rupp in 2014.

Kerr and Ingebrigtsen have not raced since the 2023 World Championship final. Pre will be Ingebrigtsen's first race of 2024 after battling Achilles problems this winter.

Both men narrowly missed Hicham El Guerrouj's WR of 3:43.13 as Nuguse smashed Alan Webb's 3:46.91 American record.

Ingebrigtsen said the wind on Hayward Field's back straight could prevent a super fast time but Nuguse is confident he's in shape to break Alan Webb's 3:46.91 American record.

From Jakob Ingebrigtsen's mile/3k double, a potential mile AR from Yared Nuguse, a potential WR from Shericka Jackson, & more, 2023 Pre has it all including Noah Lyles and Sha'Carri Richardson in the 100s.

We thought Mu's 2023 season was over but she is entered at Pre, which would be her first Diamond League since June 2022.

Berihu Aregawi won the 5k by 16+ seconds while Norman broke the Diamond League record in the 400 (43.60) and high schooler Colin Sahlman ran 3:56.24.

From Elaine Thompson-Herah and Sha'Carri Richardson in the 100 to Jakob Ingebrigtsen and Cole Hocker in the Bowerman Mile, the world and America's best are all in Eugene this weekend.

Joshua Cheptegei is looking to lower his 5,000 WR and we will get a showdown between Francine Niyonsaba and Sifan Hassan in the women's 2-mile.

After his AR in March, Fisher is favored to win his first national title but he'll have to take down reigning champ and BTC teammate Woody Kincaid.

Semenya has said she won't lower her testosterone and she's also said she won't run the 5000 so the 3000 seems to be an ideal temporary fit for her. *MB:
