Jorgensen announced via Twitter on January 19, 2017 that she and her husband were expecting a child. She gave birth to a boy, Stanley, on August 16, 2017 - almost two weeks after his due date.
In November 2017, Jorgensen announced that she was retiring from triathlon, and focusing on the marathon, with the goal of winning an Olympic gold in the discipline at Tokyo 2020. However, after suffering injuries and undergoing heel surgery during her marathon build-up, Jorgensen announced on December 4, 2019 that she will focus on qualifying in track, in either the 5,000m or 10,000m.
