Boston Marathon Route Mile by Mile

You can find terrific viewing spots along most of the Boston Marathon route.

However, if you want to be sure to watch the winners as they maintain their lead position at most points during the race, you need to be strategic when you pick your viewing location.

In this article, we'll give you the big picture of the Marathon route, plus a race course map and a mile-by-mile description. 

We'll also point out challenges the runners encounter along the course.

But most important, we'll show you where to get the best views of the winners - without getting crushed by the crowds at the finish line.

"Big Picture" of the Marathon Route

The Boston Marathon route covers 26 miles and 385 yards of sometimes hilly, sometimes flat terrain between Hopkinton, Massachusetts and Copley Square in Boston.  The race course this year follows the same route used in recent previous years.

The Marathon route starts on Route 135 in Hopkinton, a suburban community with gently rolling hills in the countryside the west-south-west of Boston. 

The race course continues east on Route 135 through the rural and suburban towns of Ashland, Framingham, Natick, and Wellesley. 

Through this stretch, the rolling terrain also continues, punctuated by small stretches of more pronounced hills.  Even though the changes in elevation mostly seem fairly subtle, competitors who are accustomed to training only on flatter ground may begin to feel some unexpected fatigue. 

In Wellesley, Route 135 merges into Route 16.  The race continues east on Route 16 into the Newton Lower Falls area of Newton, just to the east of Route 128, where it merges right at the firehouse onto Commonwealth Avenue (Route 30). 

The race continues on Comm Ave through the four challenging Newton Hills, including the notorious Heartbreak Hill. 

At the Chestnut Hill Reservoir, racers bear right at Chestnut Hill Ave to Beacon Street in Brookline until they reach Fenway Park and Kenmore Square, where they veer right onto Comm Ave again and run a few more blocks toward the city. 

At Hereford Street, the Marathon route turns right (don't ever try this in your car - normally Hereford is a one way street going left), and then turns left onto Boylston Street for the final 4 blocks.

The race finishes in Copley Square near the Boston Public Library.

Best Places to Watch the Boston Marathon Winners

You'd expect the best place to see the Marathon winners would be near the finish line in Copley Square, right?

That would be true - except for the exuberant crowds packing both sides of Boylston Street at least 20 people deep.  This density give you a low chance of spotting the winners cross the finish line - and a high chance of not being able to glimpse the runners at all.

But don't get discouraged. You can still see the winners... just not at the finish line.  It's all about picking the right spot.

Here's how to do that:

Position yourself a few miles before the finish line, and you can be almost positive that the winner of each division will be among the first five or six racers. 

The most challenging stretch of the race takes place between Miles 18-21 when the four Newton Hills crush many of the competitors (see below for mile-by-mile details). 

By the time the runners hit the 4th hill, known as the infamous "Heartbreak Hill," all but the top contenders are almost guaranteed to have fallen behind. 

Catching up with the lead pack may not be impossible at this point - but it is close to it. 

You could position yourself after Heartbreak Hill, in Mile 22... but this area around Cleveland Circle tends to be crowded - and the crowds grow even larger as you get closer to Boston.

For this reason, Mile 21, right before Heartbreak Hill, is the sweet spot for seeing the soon-to-be Marathon winners. 

Crowds are less intense so you can easily get a great view. 

And chances are good that whoever is in the lead group of runners for each division has a fair shot at being the first across the finish line.

So watch the lead group as they speed past you, and you've most likely seen the winner.

Mile by Mile Boston Marathon Route - Where to See the Race

Mile 0 to Mile 1:  Hopkinton 
Elevation at start:  490 feet
Runners gather at the Athletes' Village behind Hopkinton's Middle/High School.

The Boston Marathon route begins in Hopkinton Common, a grassy green space in this once-rural, now-suburban town. 

The race route's elevation is at its highest here - 490 feet. 

Almost immediately, the elevation drops (except for a small hill after the first kilometer) as runners begin the first of several mostly enjoyable downward miles winding through the picturesque countryside past open fields and widely-spaced suburban houses. 

The total drop during this first mile is 130 feet.

You'll see lots of large crowds of spectators clustered along Main Street here. 

Mile 1 to Mile 2:  Hopkinton 
Elevation at start:  360 feet
Slightly rolling terrain, but generally pleasant and uneventful. Crowds become much thinner. The vibe among the spectators is tranquil. It's easy to imagine that everyone is looking forward to breakfast, or at least another cup of coffee.

Mile 2 to Mile 3:  Ashland
Elevation at start:  320 feet
Pleasant and uneventful.  More rolling hills.  Route 135 is just 2 lanes here - meaning one lane in each direction.  The village of Ashland produces some cheering crowds, but otherwise runners won't notice too many spectators along this stretch.

Mile 3 to Mile 4:  Ashland 
Elevation at start:  265 feet
Pleasant and uneventful.  More rolling hills.  The route becomes less rural, with commercial areas and small strip malls.

Mile 4 to Mile 5:  Ashland - Framingham 
Elevation at start:  180 feet
Runners encounter the first significant upward slope - a long half-mile incline as they enter Framingham toward the end of the mile. Anyone not used to this kind of terrain will begin to feel the burn - although far worse is yet to come.

Mile 5 to Mile 6 - Framingham 
Elevation at start:  205 feet
Runners leave the countryside behind as they proceed along the Boston Marathon route through Framingham. 

The route becomes hillier also - three small rolling hills, resulting in a net drop of 25 feet by the end of this mile.  Front runners begin to emerge, while others drop back a bit.  

Plenty of spectators usually line up to watch here.

Mile 6 to Mile 7 - Framingham 
Elevation at start:  180 feet
Development becomes denser, with office buildings, factories, and stores lining the road around the intersection of Route 135 and Route 126.  The route is mostly flat, with a drop by the end of the mile of another 25 feet. 

Experienced runners take it easy along this stretch, as the biggest challenges lie ahead.

Less-experienced runners may relax too much - a mistake.

Mile 7 to Mile 8 - Framingham - Natick 
Elevation at start:  155 feet
Hard to tell where Framingham ends and Natick begins.  Mostly flat, with a gradual rise of about 25 feet by the end of the mile.

Mile 8 to Mile 9- Natick 
Elevation at start:  180 feet
Stores and more stores line the route.  Mostly rolling terrain, but still fairly flat.

Mile 9 to Mile 10 - Natick 
Elevation at start:  150 feet
Mostly flat, and less commercial as the runners first pass Lake Cochichuate, and then run through Natick's historic district. 

Mile 10 to Mile 11 - Natick 
Elevation at start:  170 feet
The road is flat through Natick, where the intersection of Routes 135 and 27 in Natick Center marks the first 10 miles.  Lots of crowds gather around Natick Center.

Mile 11 to Mile 12 - Natick 
Elevation at start:  180 feet
Commercial development thins out as the runners approach the bucolic environs of suburban Wellesley.  The route drops slightly, and the peaceful wooded area just to the west of Wellesley Center gives no hint of what the runners are about to experience in Mile 12.

Mile 12 to Mile 13 - Wellesley 
Elevation at start:  165 feet
The course inclines rather sharply downhill but then climbs up toward the end of the mile. For even the more experienced runners, this hints at the challenges ahead.

But it's the spectators who amp up the adrenalin along this mile, which marks almost the halfway point of the race's course.

Wellesley College, located near Mile 13, cancels classes for the day which sets the stage for what greets the runners as Wellesley students line up soon after Mile 12 to create what they call the Scream Tunnel - a wall of sound, unbroken for the duration of the race and amplified by loud music, colorful signs, high fives, hugs, and kisses to cheer on the runners as they stream past.

Mile 13 to Mile 14 - Wellesley 
Elevation at start:  145 feet
Mostly flat.

Less than 200 yards into Mile 13 is the race's halfway mark.  Runners turn left onto Route 16, and head through blocks lined with ritzy shops as the Boston Marathon route leads them east from Wellesley Center. Crowds of spectators thin out a bit here only because the somewhat narrow sidewalks constrain the numbers of viewers.

Mile 14 to Mile 15 - Wellesley 
Elevation at start:  130 feet
Mostly flat.

Runners pass the picturesque village houses and more shops on the outskirts of Wellesley, and then cross Route 9.  Crowds are usually fairly thin here.

Mile 15 to Mile 16 - Wellesley Hills - Newton Lower Falls 
Elevation at start:  160 feet
After crossing Route 9 there's a slight rise - and then after about half a mile, runners hit the sharpest descent of the race, an abrupt 100-foot drop into Newton Lower Falls.  This is where the terrain changes, and for the next 9 miles, the runners will be challenged by a series of rippling hills.

Alone, none of the hills would be particularly challenging but cumulative, they take a toll.

Crowds are still fairly thin here.

Mile 16 to Mile 17 - Newton Lower Falls - Newton 
Elevation at start:  60 feet
Almost immediately, runners pass the "Entering Newton" sign, and start a long half-mile plus uphill climb taking them along the Route 128 overpass. 

Traffic roars by below, with lots of honking from drivers who look up and spot the Marathon runners. 

The elevation of the overpass exacerbates whatever unpleasant weather elements may be at play - strong winds, driving rain, sleet, searing heat. (Remember, our Boston weather in April can bring nasty surprises.) 

The course drops a bit around Newton Wellesley Hospital, and finally gets a little flatter. 

Not usually too crowded here.

Mile 17 to Mile 18 - Newton 
Elevation at start:  115 feet
After going through a mostly flat residential area, runners turn right at the firehouse (which is on their left) onto Commonwealth Avenue (Route 30). 

Newton's four difficult hills lie ahead, and the first, "Firehouse Hill," is about to begin.  This is a steep hill, although less than a half-mile long, beginning just past the Brae Burn Country Club on the right.

Large crowds gather around the firehouse and along Comm Ave.  From here on in, expect lots of spectators lining both sides of the route. 

Mile 18 to Mile 19 - Newton 
Elevation at start:  145 feet
The course curves around quite a bit, but is mostly flat, with a small net drop of 15 feet. 

Mile 19 to Mile 20 - Newton 
Elevation at start:  130 feet
Runners encounter Newton's second hill.

Just after Mile 19 begins, runners cross Walnut Street, where the "Forever Young" statue of John A. Kelley shows Boston's famous Marathon runner as a young athlete next to his older self. 

Almost immediately, the course - now quite curvy - begins a gradual incline.  By this point, the runners are looking tired and stressed, but soon the hill becomes steeper.  It flattens out a little - only to climb again near Centre Street as the impact of this third hill another sharp incline just after Newton City Hall, hits the runners.

Mile 20 to Mile 21 - Newton 
Elevation at start:  150 feet

Mile 20 begins almost at Centre Street. 

Heartbreak Hill, Newton's fourth hill along this stretch of Comm Ave, comes just after the shops near Centre Street and forces the runners up a winding half-mile rise to Hammond Street. 

Heartbreak Hill itself isn't horrible - you probably wouldn't even feel winded if you were walking and, key point, hadn't already run for 20 miles - but it challenges the runners just as they're already exhausted by the previous hills and all those miles. 

At the hill's summit, Prudential Tower comes into sight. Crowds along this stretch are large, loud, and enthusiastic.

Crowds get even bigger after this point, so if being in large crowds makes you feel uncomfortable, stake out a spot at or before Mile 20.

Mile 21 to Mile 22 - Newton / Chestnut Hill 
Elevation at start:  230 feet
Runners pass Boston College at Mile 21 as the course plummets around the Reservoir, along with more minor ups and downs.  

The downward portions of this stretch are considered especially difficult - perhaps after the recent strain of Heartbreak Hill. 

BC's Screaming Eagles shriek, living up to their namesake, along with the rest of the large exuberant crowds.  The Chestnut Hill Reservoir is on the right, just as the runners head toward the Mile 23 mark.

Mile 22 to Mile 23 - Boston / Brighton 
Elevation at start:  150 feet
Parts of this mile are flat, and parts go downhill - tough for the runners at this point.  Crowds line Cleveland Circle, and become increasingly bigger from this point on. 

Mile 23 - Brookline 
Elevation at start:  95 feet
Crowds grow even thicker. And louder.

Mile 24 - Brookline 
Elevation at start:  60 feet
Boston University students line both sides of Commonwealth Ave, cheering almost as loudly as the Wellesley students.

Mile 25 - Boston / Back Bay 
Elevation at start:  15 feet
Runners go through Kenmore Square.  From Kenmore Square, they run along Comm Ave for a couple of blocks in the Fenway neighborhood and then a couple of blocks in Back Bay until they reach Hereford Street, where they turn right.

Every year, the Red Sox play a home game at nearby Fenway Park on Marathon Day that normally starts at 11:05 (you can confirm the schedule here).  As soon as the game is over, the crowd surges out of Fenway Park and pours into Kenmore Square.  The fastest runners have already gone past by the time the game ends - but the crowds loud cheer the rest of the runners as they strive to complete the final mile.

Mile 26 - Boston / Back Bay 
Elevation at start:  10 feet
Runners pass the big stores along Boylston Street.

Mile 26 + 385 yards - Copley Square  
Elevation at start (and finish):  10 feet
The finish line!
