Maughan was selected as part of Britain's delegation to the Ninth Stoke Mandeville Games, later known as the First Summer Paralympic Games, held in Rome in 1960. Maughan competed in only one archery event, the Women's Columbia round open. Scoring 484 points, she won Britain's first ever Paralympic gold medal. Because of disorganisation in tracking the scores, she had to be taken from the coach heading back to the Olympic village to be presented with her prize. Maughan also took part in swimming, in the Women's 50 metre backstroke complete class 5. As she was the only competitor in the race, she won by completing the full 50 metres, with a time of 1:49.2.
