The 2023 Chicago Marathon was the 45th edition of the annual marathon race in Chicago, held on Sunday, October 8, 2023.[1][2] A Platinum Label marathon, it was the fifth of six World Marathon Majors events that were held in 2023.[3][4][5] The race also hosted the age group world championships for the year.[6][7]
Kenyan runner Kelvin Kiptum set a new marathon world record, winning the race with a time of 2:00:35, and beating the previous world record of 2:01:09, set by his compatriot Eliud Kipchoge at the 2022 Berlin Marathon, by 34 seconds.[8][9][10][11] Kiptum broke free from all the other runners by the 35 km (22 mi) mark, and finished the race with a significant negative split.[12][13] This was Kiptum's third marathon, after he set the course record at the 2022 Valencia Marathon with a time of 2:01:53 in what was the fastest marathon debut ever, and then set another course record at the 2023 London Marathon with a time of 2:01:25.[14][12][15]
Dutch runner Sifan Hassan set a new woman's course record by finishing the race with a time of 2:13:44, running the second-fastest marathon by a woman, in her second marathon ever.[14][16][17] Hassan had debuted at the marathon distance with the 2023 London Marathon, which she won with a time of 2:18:33.[18] Swiss wheelchair athletes Marcel Hug and Catherine Debrunner both set course records with their victories, finishing with times of 1:22:37 and 1:38:44, respectively.[19][9][20] The marathon was Debrunner's debut race in the United States; Hug broke his own course record.[9] U.S. runner Jake Caswell claimed victory in the non-binary division with a time of 2:38:05.
Both the men's and women's records were notably set in a prototype version of the Nike Alphafly 3,[21] the latest version in Nike's line of carbon-plated "super shoes", which were originally introduced during Nike's Breaking2 project.[22]
A total of 48,398 runners and 45 wheelchair athletes finished the marathon.[23][24] First-time marathon runner Allison Naval of Evanston, Illinois, was celebrated as the millionth finisher of the Chicago Marathon since the modern incarnation's inaugural race in 1977.[25][2][26][a] Naval completed the marathon with a time of 4:23:13.[25][26]
