The Boston Marathon holds its 130th edition this Monday with 30,000 participants and a city fully immersed in one of the most recognisable dates on its public calendar. The race, organised by the Boston Athletic Association -B.A.A.-, will once again take place on Patriots’ Day, the state holiday observed by Massachusetts every third Monday in April and one that places the marathon within a broader agenda where sport, historical memory and city life share the stage.

The date is not merely the setting for the race. Patriots’ Day commemorates the battles of Lexington and Concord on 19 April 1775, regarded as the military beginning of the American Revolutionary War, and serves in Boston and Massachusetts as a day of historical identity. The marathon is its best-known sporting expression internationally, but the day also includes reenactments, ceremonies, parades, educational activities, civic events and sporting traditions that explain why the race forms part of a much wider celebration.

Patriots’ Day, the historical origin of a key date for Boston

Patriots’ Day recalls the advance of British troops from Boston towards Concord to seize colonial weapons and military supplies, a movement that led to clashes with local militias in Lexington and Concord. The day became associated with episodes such as Paul Revere’s ride, which began in Boston’s North End to warn revolutionary leaders and nearby communities of the British advance, and with the role of the so-called minutemen, militia members ready to mobilise quickly in the face of a threat.

Massachusetts made Patriots’ Day a state holiday in 1894, after decades of local commemorations linked to Lexington and Concord. Since 1969, the date has officially been observed on the third Monday in April, establishing a fixed public holiday within the region’s calendar. That change also consolidated the public dimension of the day: it was no longer only about remembering a date from 1775, but about building around it a programme involving institutions, museums, historical associations, schools, residents and visitors.

Why the Boston Marathon is held on Patriots’ Day

The link between the Boston Marathon and Patriots’ Day has existed since the race was created. The first edition was held on 19 April 1897, inspired by the marathon at the Athens 1896 Olympic Games and conceived by the B.A.A. as a long-distance race within its spring athletics programme. That first race started in Ashland, finished near Copley Square and brought together 15 runners, with John J. McDermott taking victory.

For much of its history, the race was held on 19 April, except when the date fell on a Sunday. When Patriots’ Day began to be observed on the third Monday in April, the marathon became tied to that public holiday, known in the city as Marathon Monday. The current route starts in Hopkinton and passes through Framingham, Natick, Wellesley, Newton and Brookline before reaching Boylston Street, a finish line that has become one of Boston’s most recognisable sporting locations.

Beyond the marathon: reenactments, parades and baseball at Fenway Park

The Patriots’ Day schedule extends across several municipalities linked to the American Revolution. Lexington stages the reenactment of the battle at Battle Green, community breakfasts, historical events and its annual parade; Concord and the Minute Man National Historical Park offer activities on the 1775 battles, interpretive walks and living history programmes; and Boston holds its Patriots’ Day Parade, starting from City Hall Plaza and passing through Downtown and the North End, where the figure of Paul Revere is also remembered near Old North Church.

The day also has a sporting tradition of its own beyond athletics. The Boston Red Sox usually play a morning game at Fenway Park; this Monday they will face the Detroit Tigers, continuing a custom closely associated with the holiday and the marathon atmosphere, with an early start time that fits into a city shaped by road closures and the arrival of runners. That overlap makes Patriots’ Day a distinctive date in American sport: a historic marathon, a morning baseball game and a civic programme spread across Boston and Massachusetts.

Boston Marathon week and the city around the race

The marathon has also developed its own programme in the days leading up to the race. The B.A.A. organises the Boston 5K, the B.A.A. Invitational Mile, youth races, runner activities, the Boston Marathon Expo and the Fan Fest, with champions, music, fan spaces and public programming. Monday’s race is the main event, but the movement of athletes, companions, volunteers, sponsors, media and spectators begins earlier and turns the weekend into a sporting extension of Patriots’ Day.

On Monday, the urban scale of the day is measured through road closures, parking restrictions, special services, thousands of spectators along the course and a finish on Boylston Street that shares the calendar with parades and historical events. This year’s edition keeps the traditional structure of the route and adds an organised start in six waves to manage the flow of runners, according to the planning announced by the B.A.A. for a race bringing together 30,000 participants on Patriots’ Day.
