Stephanie Morton made her Olympic debut at Rio 2016 after winning gold at the London 2012 Paralympic Games as the Pilot for Felicity Johnson in the 1km time trial tandem event. Four years later at Rio, Morton teamed up with cycling legend Anna Meares in the women's team sprint, where the duo placed fourth. Morton finished her Games campaign with two 13th place finishes in the women's keirin and individual sprint.
Having first began cycling competitively when she was 15, she came close to winning her first national titles in 2011 when she finished second in both the keirin and team sprint while also training for the 2012 Paralympics. In 2013, she won all three sprint titles at the Australian Championships before getting the chance to compete at her first Track World Championships where she finished fourth in the team sprint with Kaarle McCulloch.
Having defended both her team sprint and keirin national titles in 2014, she defeated her long-time idol and Rio 2016 teammate Anna Meares to win gold in the sprint at the Glasgow 2014 Commonwealth Games. She also claimed silver in the 500m time trial at the Games. Morton went close again to a World Championship podium in 2015, placing fourth in the sprint and sixth in the keirin.
In 2016, Morton established herself as one of the fastest women in the world, consistently posting the fastest flying 200m times, including the World Championships where she also finished fourth in the team sprint (with Meares), seventh in the keirin and eighth in the sprint.
In 2017, Morton had her most successful World Championships campaign to date in Hong Kong, winning duel silver in the individual sprint and team sprint with Kaarle McCulloch, as well as placing fourth in the keirin.
