To this day she is considered one of the best cyclists, male or female, that England had ever produced. Sheridan first got into swimming but later changed to cycling after her father bought her a bicycle at 14. In 1944 she joined the Coventry Cycling Club where she broke the club record for the 25-mile time trial in her first competition only to break her own record again two years later. She won the women's British Best All-Rounder time trial competition and was awarded the Bidlake Memorial Prize in 1950.
In 1951 she was signed by Hercules Cycle and Motor Company to break distance and place-to-place records for three years. She broke all 21 of the women's records by large margins and held all 21 W.R.R.A. records in 1955. She retired after her contract ended and became a spokeswoman for women’s cycling.
