Boston Marathon 2025 Route Guide
About the Boston Marathon Course

The Boston Marathon covers a distance of 26.2 miles, stretching from Hopkinton to the finish line in downtown Boston. The route is known for its unique terrain, with a combination of downhills early on and tough hills later in the race. The most infamous of these is Heartbreak Hill, a challenging incline that has taken down many runners over the years.
The course starts in Hopkinton and makes its way through several towns, including Ashland, Framingham, Natick, Wellesley, and Newton, before finishing in the heart of Boston. The race features several sharp turns, crowded areas, and the famous downhill sections, making it both a mental and physical test.
The Start: Hopkinton to Ashland (Mile 1-5)
The Boston Marathon starts in Hopkinton, a small town located 26 miles west of downtown Boston. It’s a relatively quiet area compared to the bustling streets you’ll encounter later, but that doesn’t mean you won’t have plenty to think about as the race begins.

Route Guide: The first 5 miles of the race are downhill, which might feel like a breeze early on, but resist the temptation to go out too fast. It’s easy to pick up speed in the beginning, but those early downhills can lead to fatigue later, especially for your quads. The course gradually slopes downhill through Ashland and Framingham, setting the tone for a fast start.
Tips:
- Keep a steady pace and focus on conserving energy for the more challenging parts ahead.
- Pay attention to your stride; let gravity help, but don’t overdo it.
- Stay mentally focused and avoid getting caught up in the excitement of the start.
The Middle Section: Framingham to Wellesley (Mile 6-13)
By the time you reach Framingham, you’ll have settled into the race rhythm. The middle portion of the course is relatively flat compared to what comes next, but it can still be tricky. You’ll pass through several towns, and while the crowd support in these areas is fantastic, it can be easy to get lost in the energy and start pushing too hard.

Route Guide: The stretch between 6 and 13 miles also brings you through the famous Wellesley College area, home to the “Scream Tunnel,” where students cheer on the runners. It’s an energizing part of the course that might give you a much-needed boost.
Tips:
- Stay focused on your pacing and don’t let the enthusiasm of the crowds throw off your strategy.
- Keep fueling properly and stay hydrated.
- If you’re aiming for a strong time, start thinking about the second half of the course and how you’ll approach the hills.
The Challenging Newton Hills (Mile 16-21)
This is where the race gets tough. After running through the flat sections, you’ll hit the Newton Hills, a series of rolling inclines that can sap your energy if you’re not prepared. These hills are notorious, with the final hill—Heartbreak Hill—coming at mile 20. It’s an infamous part of the race that’s often a make-or-break moment for many runners.

The Newton Hills aren’t particularly steep, but they’re relentless, and by the time you hit Heartbreak Hill, you’ll likely be feeling the effects of the previous miles. It’s important to pace yourself properly during this section to conserve energy for the final push.
Tips:
- Maintain a steady pace and use a short, efficient stride to tackle the hills.
- Focus on running strong but don’t push too hard on the first two hills; save your energy for Heartbreak Hill.
- Break the hills down into manageable segments and focus on reaching each peak without stressing about the overall distance.
The Descent to Boston (Mile 22-25)
After conquering Heartbreak Hill, you’re not quite home free yet. The course becomes more downhill, and although this might seem like a relief, it can put a lot of stress on your legs, particularly your quads. The final miles require mental focus to maintain form and avoid injury.
Route Guide: You’ll pass through Cleveland Circle and make your way through Brighton before heading into the city of Boston. The closer you get to the finish, the more intense the crowds become, so it’s important to stay in control.
Tips:
- Pay attention to your form, especially as you run downhill—don’t overstride or allow yourself to pick up speed uncontrollably.
- Stay focused on your goal, whether that’s maintaining a pace or pushing for a sprint finish.
- Keep an eye on the crowds and use their energy to fuel your final miles.
The Final Stretch: Boylston Street and the Finish Line (Mile 26-26.2)
The final stretch of the race is both exhilarating and exhausting. After running through the streets of Boston, you’ll make the famous turn onto Boylston Street, with the finish line in sight. The last 0.2 miles might feel like the longest part of the course, but the crowds along Boylston will give you one final burst of energy to push through.

Route Guide: The final stretch is mostly flat, but your legs will be tired from the earlier hills and downhill sections. It’s a psychological battle to keep moving forward when you know you’re so close.
Tips:
- Focus on the finish line and push through the fatigue.
- Don’t slow down—now’s the time to give it everything you have left.
- The crowd will be roaring, and that energy can help you finish strong, so tap into it.
