Fisch was part of a German team that broke the 4 × 100 m world record (with a time of 45.1) in 1956. At the 1956 Olympics in Melbourne she injured herself in the long jump, but still placed fourth with a wind-aided 5.89 m; she was supposed to also compete in the 4 × 100 m relay, but had to sit out due to the injury. At the 1958 European Championships in Stockholm Fisch was third in the long jump qualification with a jump of 5.95 m, but only reached 5.72 m in the final and placed twelfth.
