The 2020 U.S. Olympic Team Trials – Marathon was held on Saturday, February 29, 2020, in Atlanta, Georgia to determine the American athletes who will compete in the marathon event at the 2020 Summer Olympics in Tokyo, Japan. The race was hosted by the city of Atlanta, in partnership with Atlanta Track Club, USA Track & Field, and the United States Olympic & Paralympic Committee. Field sizes were historically large for the event, with 260 men and 512 women qualifying to compete. On the women's side, the top three finishers were Aliphine Tuliamuk, Molly Seidel, and Sally Kipyego. For the men, Galen Rupp defended his victory from the 2016 Trials, while Jake Riley and Abdi Abdirahman finished second and third, respectively. Despite the 2020 Olympics being postponed to 2021 due to the COVID-19 pandemic, all six qualified athletes from the Trials competed in the Olympic Marathon, which took place in Sapporo, Japan in August 2021.
