Sifan Hassan, Ruth Chepngetich and Emily Sisson will all run the 2023 Chicago Marathon on October 8th, race organizers announced this week. 

The race comes just six weeks after the World Athletics Championships conclude, a meet where Hassan is expected to compete in at least one event. 

But tight schedules and endurance-defying feats have never been a problem for Hassan. 

In her debut marathon in London this spring, Hassan rallied to take down a loaded field. 41 days later she was back on the track, winning the 10,000m and 1500m on back-to-back days at the FBK Games in Hegelo.

The challenge won’t get any easier in her second marathon. Ruth Chepngetich will try to stop Hassan and complete a three-peat in Chicago. Chepngetich almost broke the world record in 2022, running 2:14:18 to win the race by more than four minutes. The time was the second fastest in history. In 2021, Chepngetich ran 2:22:31 and won comfortably. 

American record holder Emily Sisson will also join the field. Sisson ran 2:18:29 in last year’s race to place second behind Chepngetich, breaking the national record in the process. Sisson has not run a marathon since then. In January, she broke the American record in the half marathon, running 1:06:52 in Houston. Her most recent race came at the Mini 10K in New York on June 10th.
