Sharon Lokedi got a huge win for herself and Under Armour as well as Hellen Obiri's debut fizzleed the final few miles. Aliphine Tuliamuk was first American.

Sara Hall (2:22:10), Emma Bates (2:23:18 pb), and Keira D'Amato (2:23:34) posted the best finish ever by a US women's marathon team at Worlds.

A year ago, Bates was training in Idaho preparing for a pb at the Marathon Project. That pb would not come, and she would wind up leaving Idaho for Boulder following her divorce. Now, however, she's thriving with Team Boss after a runner-up finish at the Chicago Marathon.

Ruth Chepngetich went out on world record pace, faded big time, but hung on to win as Emma Bates executed a wonderful race to finish 2nd, with Sara Hall 3rd.

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.

Des Linden, Emily Sisson, Jordan Hasay, Sara Hall, Molly Huddle, Kellyn Taylor, Sally Kipyego, Emma Bates, Aliphine Tuliamuk: Who is most likely to make the Olympic team?

It's time to start debating the 2020 Olympic Marathon Trials in Atlanta.

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?

Another top names announced include US marathon champs Brogan Austin and Emma Bates as well as Stephanie Bruce, Lindsay Flanagan, Chris Derrick, Diego Estrada and Parker Stinson.

Emma Bates ran the fastest time by an American ever in a 25k race.
