Crisp air, cooler temps … it finally feels like marathon season! The Chicago Marathon is October 13 and more than 40,000 runners will wind through 29 Windy City neighborhoods led by some of America’s top female marathoners.

The elite women’s field features five women with PRs under 2:25, led by 2018 Bank of America Chicago Marathon and 2019 London Marathon champion Brigid Kosgei (2:18:20 PR/Kenya).

But the next-fastest PR in the field belongs to Jordan Hasay, who finished third at Chicago in 2017 with a 2:20:57. She’s actually finished third in all three of her marathons — including Boston 2017 and Boston 2019. She holds the American record for fastest marathon debut, but after her two 2017 marathons, she missed her next two planned marathons with repeated fractures in her left heel. Hasay ran 1:12:35 at Rock ’n Roll Philly in mid-September and posted on Instagram that she was “really excited” about the effort while in the midst of heavy mileage.
