Sara Hall and Zane Robertson rave about them. ""I definitely can run faster in them. I can't really imagine going back to anything I've run in before after running in these," said Hall in ad that features her.

Hall thinks she despite becoming a parent, not because of it, but says she was willing to give up running to be a mom. "I see a correlation where my kids feel empowered to go after their dreams. Before kids, I struggled with not always seeing the positive impact of my running on others. It feels really self-centered. The upside now is that I don’t have as much of a conflict with that. I see the positive effects in real time.”

The Marathon Project Champions Sara Hall and Marty Hehir joined us to talk their great days in Arizona.

Live results and leaderboards for The Marathon Project.

Hall is planning on running the first half in 69:40, while the next group is slated to hit halfway in 71:30. Kellyn Taylor, Stephanie Bruce, Emma Bates, and D'Amato are among the US stars chasing PBs in the desert.

Let this serve as your official "American record alert." While Ryan refused to use those words, he said he'd like to see Sara go out in 69:40 so we'll let you do the math. "This has been the fittest I've ever seen her. Every buildup she gets better and better," said Ryan.

Mark your calendars, the February 19th race is something athletics fans can get excited about. The marathon WR holder Brigid Kosgei vs. the half marathon WR holder in Ababel Yeshaneh headline the women's race. For the men, we get a replay of gold vs silver from World Half in Jacob Kiplimo vs. Kibiwott Kandie. Every time Yeshaneh and Kosgei have raced so far, one of them has broken the WR. And Sara Hall of the US is making the trip.

Kosgei winning convincingly may not have been a shock but the name of the second-place finisher sure was, Sara Hall.

An American hadn't finished in the top 3 in London since 2006 but Sara Hall ran the race of her life and mowed down everyone in the field save Brigid Kosgei (2:18:58) to finish second in 2:22:01 after outkicking world champ Ruth Chepngetich. US Olympian Molly Seidel was 6th (2:25:13).

The bad news: an American is almost certain to get lapped in Sunday's London Marathon. The good news: you can get lapped in London and still run really, really fast. We preview the chances of Jared Ward, Sara Hall, Molly Seidel, and Lindsay Flanagan. Could Sara Hall possibly break Deena Kastor's 2:19:36 AR?

The 2020 London Marathon field is out and it's amazing. We tell you who is in, who is out and along the way we wonder when Galen Rupp will next race. *MB: London Marathon elite fields 2020

The men's race has eight men who have run sub-2:05 including Mosinet Geremew (2:02:55) and Mule Wasihun (2:03:16) while the women's race also has world champ Ruth Chepngetich and former London winner Vivian Cheruiyot. Mo Farah will be a pacer for the men going for the 2:11:30 Olympic standard.

World records were set in the half marathon up to 100km.

Inspired by the success of last month's Quarantine Backyard Ultra, a handful of elite runners will attempt to break treadmill world records across five distances next week. "We are 100% sure that we are going to break these records in this race," says meet director Tyler Andrews, who will be aiming for the marathon/50k records. "We want to have actual, really good athletes just totally destroy them and set them way out of reach."

Jonathan Gault revisits one of the most-hyped races in the history of US high school cross country, in which the top three finishers all eventually became American record holders. Plus X-ray graphics, Discmen, hanging chads, and why Sara Hall's win in the girls' race was way better than you remember.
