On Sunday, Emily Sisson ran her first mass marathon since dropping out of the Tokyo Olympic trials.
She was better than ever at the Chicago Marathon, breaking the record for the fastest women’s marathon by an American.
Sisson, 30, finished second overall in 2:18:29 – 17 seconds faster than the previous record of 2:19:12, set by Keira D’Amato in Houston on Jan. 16.
Sunday's Chicago Marathon was her first time lining up for the distance in 2 1/2 years.
At the 2020 U.S. Olympic Marathon Trials, Sisson was unable to finish the race despite being one of the pre-race favorites.
