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.
The Boston Marathon was first run in April 1897, inspired by the revival of the marathon for the 1896 SummerOlympics in Athens. It is the oldest continuously running marathon, and the second longest continuously running footrace in North America, having debuted five months after the Buffalo Turkey Trot.
Its the 121st year of the Marathon.
