Plus Cooper Teare is in the 5,000 and the first 2025 installment of the great Peruth Chemutai-Winfred Yavi rivalry in the women's steeplechase. *Official 2025 Doha DL Live Discussion Thead (+ Live reaction show Friday at 2 pm ET)

Cole Hocker, Yared Nuguse, and Josh Kerr all return to action in Miramar, while Jamaican star Kishane Thompson will race his first 100m of 2025 in China.

Assefa and Hassan, the #2 and #3 fastest women in history, clashed in the final 400m in Paris when Hassan tried for a late inside pass. Expect another tight finish in London on Sunday.

We have boots on the ground reporting from London. Sawe's coach Claudio Berardelli, who has coached the likes of Evans Chebet, Martin Lel, and Benson Kipruto, said "I've done this job for 21 years. I'm not sure I've ever coached a guy like [Sawe]."

Please read this preview now. It's one of Jonathan Gault's best previews and has us PUMPED for Sunday. Olympic champ Tamirat Tola and Valencia champ Sabastian Sawe (2:02:05 pb) are also part of a LOADED men's field that features four major champs from 2024.

Mantz said his first Boston appearance in 2023 dented his confidence and affected his racing in 2024, but he is ready to put that behind him on Monday. Plus two-time champ Evans Chebet is feeling healthy and ready to reclaim his title.

No woman has 3-peated in Boston this century. Will Hellen Obiri end that streak on Monday? And do the Americans Keira D'Amato, Sara Hall, Emma Bates and Dakotah Popehn have much of a chance?

Olympic 1500 medalists Cole Hocker, Josh Kerr, and Yared Nuguse will face  each other and Olympic 800 medalists Emmanuel Wanyonyi & Marco Arop and American record holder Bryce Hoppel twice in the span of less than 24 hours.

Michael Johnson's quest to reinvent track and field starts on Friday. Some BIG names like Sydney McLaughlin-Levrone, Gabby Thomas, and Cole Hocker have signed up for the new series, but some of the biggest stars in the sprint world like Noah Lyles, Sha'Carri Richardson, Grant Holloway and even Jamaicans like Kishane Thompson and Shericka Jackson have given it a pass. Some even will be competing elsewhere this weekend. Will the format that focuses on doubling be a hit with the fans?

After 28 hours of travel, we have boots on the ground at World Indoors. We give you a look at the intimate stadium and talk about WR holders  Grant Holloway, Mondo and more. The meet starts Thursday night in the US (Friday morning in China).

All six US women's mid-d/distance entries have a legitimate shot at the podium in Nanjing, including Nia Akins and Shelby Houlihan.

The World Indoor Track and Field Champs start Friday in China. Jakob Ingebrigtsen goes for the 1500/3000 double while American Josh Hoey is the favorite in the 800.

With a sub-2:02 800 and sub-4:30 mile required just to qualify for the meet, the women's middle-distance events should be incredible. The 800 features three NCAA champions in Whittaker, Roisin Willis, and Michaela Rose

We break the distances races down for you like only LetsRun.com can. UNC's Strand has set NCAA records in the mile (3:48.32) and 3000m (7:30.15) this season and will be seeking his first NCAA title in Virginia Beach. Will Washington win its 6th straight 1500/mile title? Can the OK State men three-peat in the DMR? And who is favored in the team battle?

It's a wild weekend for distance fans. In Tokyo, LRC's top two men's marathoners of 2024, Benson Kipruto and Deresa Geleta, take on 5k/10k WR holder Joshua Cheptegei. Plus there are Team USA spots for the World Half on the line in Atlanta where five male Olympians will seek 3 spots and the last BU meet of the year is on Sunday as well. And it's conference championship weekend at the NCAA level where 25 sub-4 milers will compete at the Big 10 meet.

The women's distance fielsd are LOADED - the 3,000 (Shelby Houlihan, Nikki Hiltz, Emily Mackay, Whittni Orton) and 1500 (Houlihan, Hiltz, Heather MacLean, Sinclaire Johnson) may be the races of the meet, while the high school junior Wilson faces a strong field in the men's 400. *MB: Official 2025 USA Indoor Discussion Thread

In a one-on-one interview ith LRC, Valby said she adapted smoothly to altitude training in Flagstaff and is loving training with Mark Coogan and New Balance Boston. "People said [the altitude] would hit me, but it never really hit me."

With Noah Lyles v Marcell Jacobs in the 100, Grant Fisher v Josh Hoey v Jake Wightman v Graham Blanks in the 1500, Parker Valby making her pro debut, and Olympic champs Julien Alfred, Rai Benjamin, Masai Russell and Grant Holloway all racing, this meet is loaded.

Ethan Strand and Colin Sahlman are both in the mile and Cooper Teare's NCAA record of 3:50.39 could be under threat. Plus meet New Mexico's World U20 champion Ishmael Kipkurui.

With Conner Mantz, Clayton Young, Joe Klecker, Hillary Bor, and more, the US men's field is stacked but a cold, windy forecast could prevent truly fast times. Meanwhile Weini Kelati will attempt to become the first American in 10 years to win the women's race.
