The 2025 Boston Marathon, the 129th edition of the race, is scheduled to take place on Monday, April 21st. This year's race also marks the 250th anniversary of Patriots' Day. The race starts in Hopkinton and ends on Boylston Street in Boston.

The Boston Marathon is an annual marathon race hosted by several cities and towns in greater Boston in eastern Massachusetts, United States. It is traditionally held on Patriots' Day, the third Monday of April.[1] Begun in 1897, the event was inspired by the success of the first marathon competition in the 1896 Summer Olympics.[2] 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 seven World Marathon Majors. Its course runs from Hopkinton in southern Middlesex County to Copley Square in Boston.

The event attracts 500,000 spectators along the route, making it New England's most viewed sporting event.[4] Starting with just 15 participants in 1897, the event has grown to an average of about 30,000 registered participants each year, with 30,251 people entering in 2015.[5] The Centennial Boston Marathon in 1996 established a record as the world's largest marathon with 38,708 entrants, 36,748 starters, and 35,868 finishers.[4]
