She won the silver medal at the 2018 World Championships. At junior level, she also won silver at the 2008 European Junior Championships.

Schleu was leading the competition at the 2020 Tokyo Olympics when she was unable to successfully complete the show jumping event, moving her from first to last place, and an eventual 31st place. Her trainer, Kim Raisner was sent home from the Olympics after footage showed her seemingly punch Schleu's assigned horse for not performing in a desired manner. The horse named Saint Boy was randomly assigned from a pool of 18 and had also for Russian Olympic Committee athlete Gulnaz Gubaydullina (32nd overall), refusing three barriers to jump in the second half of the equestrian course. Schleu has also faced a backlash against her repeated use of the whip and rough handling of her horse. The incident prompted German Olympic team member and equestrian medal record holder Isabell Werth to criticize Pentathlon's use of horses; she stated that "Pentathlon has nothing to do with equestrian sport" and treats horses as "a means of transport to which the athletes have no connection." Werth also expressed sympathy for Schleu, whom she saw as a victim of the system of the sport.

On January 13, 2022, her legal team announced that an earlier lawsuit had been dropped; both Schleu and Raisner had faced legal action, with the German Animal Welfare Association filing a criminal complaint against the pair on August 13, 2021. Schleu agreed to donate €500 to charity, defense attorneys said this did not constitute an admission of guilt.

In response to this issue, Modern pentathlon's governing body has voted to remove horse riding from in its programme at the Olympics after the Paris 2024 Games British media reported.
