She reached the peak of continental competition at the age of nineteen by winning the gold medal in the long jump at the 1958 European Athletics Championships in Stockholm. Her winning mark of 6.14 m (20 ft 1 ⁄2 in) was a championship record by ten centimetres (improving the four-year-old record of Britain's Jean Desforges).
At national level that year she only placed third in the long jump at the West German Athletics Championships. Over her career she a national runner-up once (1959) and twice more a third-place finisher (1960 and 1963), but she never won the West German title. She was, however, twice a national sprint champion indoors over 60 metres, winning that title first in 1960and again in 1963. She stopped competing at a high level shortly after getting married.
