Seifu Tura Abdiwak of Ethiopia and Ruth Chepngetich of Kenya won Sunday in the return of the Chicago Marathon, which was scrapped last year amid the coronavirus pandemic.
Abdiwak, who placed sixth in the Chicago race in 2019, finished in 2 hours, 6 minutes, 12 seconds. Galen Rupp was second in 2:06:35, followed by Kenya’s Eric Kiptanui with a time of 2:06:51.
Rupp won the Chicago title in 2017, becoming the first American man to accomplish the feat in 15 years.
Chepngetich took the women’s race, finishing in 2:22:31. Emma Bates of the U.S. was second at 2:24:20.
University of Illinois grad Tatyana McFadden won the women’s wheelchair division at 1:48:57, while Champaign’s Daniel Romanchuk (1:29:07) claimed his third consecutive Chicago Marathon title in men’s wheelchair.
Around 35,000 runners competed in Sunday’s 26.2-mile event. Organizers canceled last year’s race due to health concerns for runners, spectators and volunteers. Registered participants had to provide either proof of a COVID-19 vaccination or negative test results.
