Why Is the Boston Marathon on a Monday? 1775, 1897 and 1969

Why is Boston Marathon on Monday? Because it is run on Patriots' Day, the holiday that recalls the first battles of the American Revolutionary War, on April 19, 1775. It all got locked in during 1969, when this Massachusetts holiday became the third Monday of April.

01April 19, 1775: Shots Fired

At Lexington, then at Concord, Massachusetts, militiamen face British soldiers. At Lexington, a shot rings out: “historians still debate who fired it,” notes the American Battlefield Trust. These clashes start the American Revolutionary War. More than a century later, Massachusetts turns the date into a holiday.

021894: A Holiday for April 19

In 1894, Massachusetts creates Patriots' Day. According to the Kennebec Journal, it replaces Fast Day, an old day of penance inherited from the 17th century. The date is that of the battles: April 19, whatever the day of the week.

We will hold the race on whatever date Patriots Day is legally celebrated in Massachusetts

031897: 15 Men in Ashland

Three years later, John Graham, a member of the Boston Athletic Association (B.A.A.) and manager of the U.S. team at the 1896 Athens Games, comes home with an idea: a marathon in Boston. On April 19, 1897, 15 men show up in Ashland, in front of the Metcalf mill, for 24.5 miles to Boston. The start is given at 12:19 p.m., according to the next day's Boston Globe. John McDermott, of New York, wins in 2 hr 55 min 10 sec. Only ten runners make it to the end. That April 19, 1897, by the way, falls on a Monday, but it's a calendar coincidence.

04Seven Decades of Shifting Days

Until 1968, the race follows the date, not the day. According to B.A.A. archives reported by Boston.com, it has been held on every day of the week from Monday to Saturday: when April 19 fell on a Sunday, they ran on Monday. The last marathon held on a day other than Monday is the 1968 edition, on Friday, April 19. Amby Burfoot wins it.

05Why Is Boston Marathon on Monday? Since 1969

In February 1968, Governor John Volpe signs a law moving holidays to Mondays, Boston.com reports. Patriots' Day becomes the third Monday of April, starting in 1969. A Lexington lawmaker, Lincoln Cole, protests: nobody would think of moving the Fourth of July to the first Monday of July. Race director Will Cloney settles it: “We will hold the race on whatever date Patriots Day is legally celebrated in Massachusetts.” Only the pandemic has moved it since: in 2020, the April edition was postponed and then run virtually, and the 2021 race was held in the fall, according to the B.A.A.

06Red Sox and the “Scream Tunnel”

A Monday off needs some entertainment. According to the Boston Globe, the Red Sox have played at home, at Fenway Park, every Patriots' Day since 1959. Since 1968, the game has generally started around 11 a.m., so fans can walk over to Kenmore Square afterward and cheer on the runners. In Wellesley, around the halfway point, the college's students scream as the pack goes by. According to the college, quoted by Boston.com, the tradition dates back to 1897, when students supposedly cheered on a Harvard runner. The Boston Daily Globe of April 20, 1911, already describes “hundreds of Wellesley college girls” along the road.
