The first running of the B.A.A. Road Race commenced at the site of Metcalf's Mill in Ashland and finished at the Irvington Street Oval near Copley Square. John J.

Today, 19 countries can claim a Boston Marathon champion. The United States leads the list with 41 triumphs.
Wednesday, April 19, 1911: The legendary Clarence H. DeMar of Melrose, Massachusetts won his first of seven Boston Marathon titles.
