Kenya’s defending champion John Korir leads a stacked field at the Chicago Marathon, the penultimate World Marathon Major of the year.
Korir’s 2:02.44 victory last year was the second-quickest time in the race’s history, and the eighth-fastest man in history and Boston Marathon winner is hoping to best it with a sub-2.01 this time round – emulating the late Kelvin Kiptum, who set the world record of 2:00.35 at this very race in 2023.
The women’s race will see a new champion crowned, with Ethiopia’s Valencia Marathon winner Megertu Alemu bidding to improve on her third-place finish in 2023, and compatriot and Frankfurt champion Hawi Feysa providing stiff competiton on her debut.
British interests will be led by Calli Hauger-Thackery, the second-fastest British marathon runner of all time, and Marc Scott.
