Birnie Duthie was the 1933 and 1934 British combined champion and was selected as a reserve for the 1936 Olympics, but came into the team after Elizabeth McFie injured her shoulder on a trial run. After finishing second in the downhill and combined at the 1938 British Championship, Duthie was made captain of the British women’s team at the FIS World Championships that year. In 1939, Duthie came second in the slalom at the British Championships at St. Moritz and also announced her retirement as captain of the Great Britain team that year. After the war she wrote skiing articles for The Tatler magazine, and embarked on a new sporting career as a croquet player. She was a member of the famous Hurlingham Club.
