When the women's PTWC wheelchair category was left out of the Para Triathlon programme of the Rio 2016 Paralympic Games, USA's Kendall Gretsch didn't dwell on what might have been. Instead, she took up Para Nordic Skiing, going on to win gold at the Pyeongchang 2018 Winter Games. After finally getting her shot at triathlon glory at Tokyo 2020 and winning the title in the most dramatic fashion, she is now heading to Beijing and hoping to defend her winter titles for the first time.
