"After I won Olympic marathon I was not expecting to win," said Jepchirchir, who had just 13 weeks in between the Games and New York. "I tried my best to make sure I complete my workouts, my preparations... I"m so happy today." American Molly Seidel, who took home the bronze from the Tokyo Games, finished fourth and disclosed after the race that she broke two of her ribs a month ago and had considered withdrawing. "Probably two weeks ago it was extremely painful and it was hindering my ability to do anything," said Seidel.
