The Boston Marathon is an annual marathon hosted by several cities in greater Boston in eastern Massachusetts, United States. It is always held on Patriots' Day, the third Monday of April. Begun in 1897, inspired by the success of the first 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.
The city has two symphony orchestras, the New Philharmonia Orchestra of Massachusetts and the Newton Symphony Orchestra. Each April on Patriots Day, the Boston Marathon is run through the city, entering from Wellesley on Route 16 (Washington Street) where runners encounter the first of the four infamous Newton Hills.
