Gwen Jorgensen, the first U.S. Olympic triathlon champion, will race her second marathon in Chicago on Oct. 7 as she prepares for a Tokyo 2020 run on the roads.
Jorgensen, 32, joins a Chicago Marathon field that includes Jordan Hasay, the second-fastest U.S. female marathoner in history, and world bronze medalist Amy Cragg.
Jorgensen made her marathon debut in New York City on Nov. 6, 2016, two and a half months after winning the Rio Olympic triathlon. The former University of Wisconsin runner was 14th in 2 hours, 41 minutes, 1 second, more than 16 minutes behind the winner, on limited marathon training.
