The Boston Marathon is an annual marathon hosted by the U.S. city of Boston, Massachusetts, on Patriots' Day, the third Monday of April. Begun in 1897 and inspired by the success of the first modern-day marathon competition in the 1896 Summer Olympics, the Boston Marathon is the world's oldest annual marathon and ranks as one of the world's best-known road racing events. It is one of five World Marathon Majors. - Source: Wikipedia
