In 2017, Schmidt came second in the 200 metres event at the under-20s German Championship. At the 2017 European Athletics U20 Championships, Schmidt was part of the German 4 × 400 metres relay team that finished second, alongside Vanessa Aniteye, Meike Gerlach and Corinna Schwab. Their time of 03:33:08 was faster than the previous age group world record, but they finished behind the Ukrainian team, who set the new world record. It was the first medal at the Championships for an Ingolstadt athlete since 1999. Schmidt also set a personal best time of 54.23 seconds in a qualifying round of the individual 400 metres event at the Championships. She was withdrawn from the individual 400 metres final in order to focus on the relay event. In the same year, she came second at the German under-20 Championship in the 400 metres event.
