Stefanie Koyuncu was born into racing, her father being the successful German trainer Mario Hofer. She started her career as an amateur rider and won the championship for amateurs in Germany in both 2005 and 2007, before going on to win three apprentice championships.
Koyuncu, who until recently competed under her maiden name Hofer, has been the leading female rider in Germany throughout her career. She was the first female to win a Group race in her country when in 2012 she rode Smooth Operator in the Silberne Peitsche (Gr.3) in Munich. She also rode the same horse to Listed victory in the Mercedes Benz-Sprinterpreis in Baden-Baden.
In 2011 Koyuncu became only the second woman to ride in the German Derby, steering Andreas Wöhler-trained 100-1 shot Mi Senor to 12th place. Koyuncu then went on to ride for the Girls Team in the 2014 Shergar Cup, in which the team finished in second place. She competed in the inaugural LJTWC at Bro Park last year.
