In the end, Ashton Eaton and Briannne Theisen-Eaton agree, it was time.
Track and field's power couple came to a mutual decision to retire from the sport after thinking about it following the 2016 Olympics and through the fall.
"After a couple of months went by and it was getting into the time when we normally would start training. I found myself thinking, 'It's not in the cards,'" Eaton said. "I thought the excitement would come back for one more year. It didn't."
They will go out on top. Eaton, world record-holder in the decathlon, won his second Olympic gold medal this summer in Rio de Janeiro.
