The legendary Clarence H. DeMar of Melrose, Massachusetts, won his first of seven Boston Marathon titles. However, on the advice of medical experts, DeMar initially “retired” from the sport following his first title. He later won six titles between 1922 and 1930, including three consecutive titles from 1922 through 1924. DeMar was 41 years old when he won his final title in 1930.
