– Ethiopia’s Sutume Kebede is the fastest marathoner in the world this year with her 2:15:55 from her win at the Tokyo Marathon in March. She was a controversial snub from the Ethiopian Olympic marathon team.

– The top Americans in the field include Keira D’Amato (2:19:12 PB, No. 2 on the U.S. all-time list) and Betsy Saina (2:19:17 PB, No. 3 on the U.S. all-time list). D’Amato recently announced that she has started working with coach Ed Eyestone and has moved to Utah to train for Chicago. Saina has been training in Kenya.

– Last year in Chicago, Emma Bates was vocal about possibly attacking Emily Sisson’s American record. However, she tore her plantar fascia during the race and still finished in 2:25:04 for 13th place. The injury later caused her to scratch from the U.S. Olympic Marathon Trials. She returned to racing at the Boston Marathon in April and was the top American in 2:27:14.

– On the men’s side, Amos Kipruto holds the fastest personal best with a 2:03:13 from the 2022 Tokyo Marathon. He has not finished a marathon since his victory at the 2022 London Marathon.

– Kelvin Kiptum, last year’s champion and world record holder, died along with his coach in a car crash in Kenya in February.

– 25-year-old Vincent Ngetich of Kenya has taken well to the marathon with a runner-up finish at the Berlin Marathon last fall in 2:03:13 and a third place finish in March’s Tokyo Marathon in 2:04:18. He is looking for his first Major Marathon victory.

– The fastest American in the field is Zach Panning, who finished sixth at the U.S. Olympic Marathon Trials and has a personal best of 2:09:28. He will be joined by fellow sub-2:10 marathoners Brian Shrader and C.J. Albertson.

– Daniel Ebenyo, the No. 1-ranked 10,000m runner in the world and a silver medalist at last summer’s World Championships in Budapest, will be making his marathon debut after being left off the Kenyan Olympic team. He fell during the Kenyan 10,000m trials selection race at the Prefontaine Classic in May. Despite having one discretionary spot for selectors, Athletics Kenya chose to send the top three finishers from the race to the Summer Games in Paris.
