At the Gold Coast 2018 Commonwealth Games, Tess Routliffe finished third in the S7 50-m butterfly in a personal best time.
Two years earlier at the Rio 2016 Paralympic Games, Routliffe brought home her first Paralympic medal, a silver in the 200-m individual medley in Canadian record time. She made the finals in four other events: 100-m breaststroke (4th), 50-m freestyle (5th), 100-m freestyle (6th) and 50-m butterfly (7th).
Routliffe burst on the international stage in 2015. At the Parapan American Games in Toronto she won four gold medals with victories in the 50-m freestyle, 100-m freestyle, 100-m backstroke, 100-m breaststroke, as well as silver in the 200-m individual medley.
She raced in in nine events a couple of weeks earlier at the 2015 IPC World Championships, winning silver in the 200-m IM. She also posted five fourth-place finishes.
Routliffe showed her potential at the 2014 Pan Pacific Para swimming Championships by reaching the final in six individual events at age 16. The highlight was a silver medal in the S7 100-m breaststroke.
