text: In this Aug. 19, 2016, file photo, gold medal winner Chloe Esposito of Australia competes in the equestrian portion of the women's modern pentathlon at the Summer Olympics in Rio de Janeiro, Brazil. Esposito announced in late January that a “wonderful, unexpected surprise” had occurred and that the Australian wouldn’t be able to defend her modern pentathlon gold medal at the Tokyo Olympics. She was pregnant with her first child. Two months later Esposito and thousands of other Olympic athletes learned that the Tokyo Games would be put off by a year until July 2021 because of the coronavirus pandemic. While for some it meant more time to recover from injuries or extra time to prepare, Esposito realized it might give her a second chance to be in Tokyo next year.
