In April 2017, Downie represented Great Britain at the 2017 European Championships in Cluj-Napoca, Romania, where she made history by qualifying for all five individual finals. The next day, she became the first British gymnast to win the all-around title at a major international competition, beating Hungary's Zsófia Kovács and France's Mélanie de Jesus dos Santos. She also won silver medals on vault and floor, and a bronze medal on the uneven bars. At the beginning of August she underwent an ankle surgery due to an injury she had dealt with at both the British Championships and European Championships that year. The surgery means that she will not be able to attend the 2017 World Artistic Gymnastics Championships, stating on her instagram account that she plans on her next major international competition to be the 2018 Commonwealth Games.
