From Jordan Hasay (50%) to Stephanie Bruce (5%), we break down the odds for the  contenders at the 2020 US Olympic Trials.

Paula Radcliffe's legendary 2:15:25 world record is history after 16+ years.

American record alert. Jordan Hasay says she's going out in 70 flat.

The world's best marathoner Brigid Kosgei is racing Chicago and that means Paula Radcliffe's 17-year-old course record of 2:17:18 is in jeopardy. Could Deena Kastor's American record also fall?

Kamworor ran fast, Jordan Hasay didn't. Shannon Osika and Elise Cranny keep improving and yes Woody MF Kincaid.

Defending champ Brigid Kosgei is back, but Jordan Hasay is the only other woman faster than 2:22:56. Boston champ Lawrence Cherono & Dubai champ Getaneh Molla join Mo Farah & Galen Rupp in the men's race. And Amy Cragg is a scratch.

For the first time in 33 years, the defending Boston marathon women's champion is an American, Des Linden. That the good news. For the bad news, read the article.

With Cragg, Thweatt and Jordan Hasay, organizers say this is the deepest American women's field in Chicago history.

Jordan Hasay is back at Chicago as well after her third place 2:20:57 run last year.
