Benfare's doping case is expanding. Her sister Sofia Benfares has also tested positive.

Traces of the performance-enhancing drug Epo were found in her blood sample. Her father justified the doping finding by taking medication for cancer. Doubts about this are growing. In 2022 she won the German championship title over ten kilometers on the road. In 2019, the Ben fares sisters joined LC Rehlingen in Saarland, but they train independently of the club under the aegis of their father.
