A very experienced skier, but with no major titles to her name, Biddy Armitage was selected for the British team at the 1938 World Skiing Championships at Engelberg, Switzerland. Unfortunately, the war years interrupted her career, until 1946 when she was in the Ski Club of Great Britain team that was invited to compete at the Holmenkollen, in the first post-war international meeting at the famous Norwegian venue. Armitage married Wing Commander Hilary Duke-Woolley in November 1947, and a few months later took part in the slalom at the St. Moritz Olympics, but was outclassed and finished nearly one minute behind the American winner Gretchen Fraser.
