Noh qualified for the South Korean team pursuit team at the 2018 Winter Olympics in October 2017. However, because International Skating Union rules state that skaters in the team pursuit must also compete in an individual event, Noh's position in the team was uncertain up until two weeks prior to the Olympics. The Korea Skating Union attributed this to an administrative error on their behalf. Two Russian skaters withdrew and Noh was entered into the women's 1500 metres, where she finished 14th. After failing to make the semi-finals in the women's team pursuit, her teammates Kim Bo-reum and Park Ji-woo appeared to blame her for the poor result. She was later seen crying and comforted by team coach Bob de Jong.
