Boston is the oldest annual marathon in the world, and it wears that history differently than most majors — this isn't a race you simply sign up for. For the vast majority of the field, running Boston means qualifying for Boston first, and that single fact shapes almost everything else about the event: the culture around it, the size of the crowds, and the reputation the race has built over more than a century. This guide is a starting point — the rest of RaceRove's Boston coverage goes deep on the course, the qualifying system, the weather, and the logistics; this page is where to get oriented before diving into those.

What makes Boston different

Run every Patriots' Day (the third Monday in April) and organized by the Boston Athletic Association, the Boston Marathon is one of the Abbott World Marathon Majors, alongside Tokyo, London, Berlin, Chicago, New York, and Sydney. What sets it apart from the rest of that group is entry: Boston is the only major where the overwhelming majority of the field has already run a qualifying time at another certified marathon before they can even apply. That single design choice is why finishing Boston carries a specific kind of weight in the running world, and why the letters BQ — Boston Qualifier — function as their own kind of shorthand.

The race also falls on Patriots' Day, a Massachusetts state holiday, and Marathon Monday has grown into a civic event as much as a sporting one. The Boston Red Sox have played a home game at Fenway Park on Patriots' Day morning since the late 1950s, with a late-morning first pitch timed so fans can walk over to Kenmore Square after the final out to catch the marathon's leaders passing by — one of the more unusual crossovers in American sports, and a reminder of how deeply the race is woven into the city's calendar.

The course, in brief

The race is point-to-point, starting in the small town of Hopkinton and finishing 26.2 miles later on Boylston Street in Boston's Back Bay. The route runs through eight cities and towns, dropping net elevation early before the course's defining test: a stretch of climbs in Newton, in the race's back third, that culminates in the hill the whole course is built around. RaceRove's dedicated course and elevation guides cover this in full detail; the short version is that Boston rewards patience far more than its downhill reputation suggests.

How people get in

Most Boston entrants qualify by running a certified marathon within a set time standard for their age and gender, then applying during a single registration window — though hitting the published standard is often not enough on its own, since the field is capped and the fastest applicants relative to their standard get priority. A smaller share of the field comes in through the BAA's official charity program, which pairs runners with vetted nonprofits in exchange for a fundraising commitment. Both paths are covered in depth in RaceRove's dedicated qualifying and charity guides, since the specifics genuinely change from year to year.

Weather you should expect

New England in mid-April is unpredictable, and Boston's history reflects that: the race has been run in extreme heat, in driving cold rain, and in nearly every condition between. The point-to-point course also runs largely west to east, which makes wind direction — tailwind or headwind — a genuine variable in how the day plays out. Don't assume the forecast a week out is the forecast on race morning.

Race week logistics

Because the course is point-to-point and starts in a town with essentially no infrastructure for tens of thousands of runners, getting to the start is its own logistical exercise — most runners rely on official buses that depart from central Boston hours before the race begins, rather than traveling to Hopkinton directly. Where you stay, how you get to the start, and how spectators track you along the route are all shaped by that structure, and RaceRove's transportation and hotel guides walk through the practical details.

Planning your trip

Boston rewards runners who treat it as a full trip rather than a single morning — between the point-to-point course, the qualifying culture, and the scale of the event, there's more to plan around than a typical race weekend. If you're comparing it against other majors on your calendar, RaceRove's marathon listings are a good place to keep exploring, and the race's own data card on this page has the specific numbers worth checking as your trip comes together.
