Cycling
At the 1950 British Empire Games in Auckland, Tredrea competed in the men's 10-mile scratch race, but was unplaced.[3] He went on to have a career as a professional cyclist.[4]
In his later years, Tredrea suffered from Parkinson's disease. In 1993, he took up cycling again to help control the disease, and became active in masters cycling.[4][5]
