Baystate Marathon training plan: course, start dates, and plan options
Lowell, MAOctober 17, 2027
The Baystate Marathon runs a double loop along the Merrimack River in Lowell, Massachusetts, crossing the Rourke Bridge three times and covering the same stretch of riverbank twice.

That's why the race has the reputation it has. In 2025, 22.9% of its 1,140 finishers ran a Boston qualifying time, and the rate has sat above 22% every year since 2021. Runners come here to run a number. The flip side of a flat double loop is that it gives you nothing to hide behind and no hill to blame.

The course: two laps of the Merrimack, and one hill worth naming
The Baystate Marathon starts in front of the Tsongas Center in Lowell and runs a double loop along both banks of the Merrimack River, out toward the Tyngsboro Bridge and back over the Rourke Bridge, finishing where it started. The only real climbs are a gradual rise near mile 2 and a quarter mile hill inside the final two miles.
Take the early miles seriously in the other direction. From Pawtucket Street the course crosses the Western Canal inside the first tenth of a mile, picks up Middlesex Street, then swings through Chelmsford on Princeton Street with a gentle downhill grade that will happily hand you twenty seconds you did not plan on. There's another minor rise where the course crosses the old B&M rail line before Vinal Square in North Chelmsford.
The second lap is where the race is decided. The organizers mark 'The Wall' at mile 20, which lands with the Rourke Bridge still to come at 22.5. From there it's the UML Bellegarde Boathouse at 23, Pawtucket Falls, then a final hill the race itself calls not steep and only a quarter of a mile long. It sits inside the last two miles and it's the last thing your legs want.
How to train for Baystate
Train for the Baystate Marathon by practicing even effort on flat ground and by rehearsing the second lap. A double loop rewards runners who can hold one pace for three hours with no terrain to break it up, and it punishes anyone who banks time early because the road felt easy.
Build long runs that repeat a loop rather than point somewhere new. Run 8 to 10 miles of familiar road, come back through your start, and go again at the same effort or slightly faster. That is exactly the demand at mile 13 here, when you come off the Rourke Bridge and head back out Pawtucket Street a second time. Runners who have never done it find the repeat lap harder than anything in the elevation profile.
Then do the small specific work. The Princeton Street descent and the two minor rises each come around twice, so a few sessions of controlled downhill running plus short uphill surges on tired legs will pay for themselves. Finish one long run every couple of weeks with a quarter mile climb in the last two miles, because that is what the end of this course looks like.
Getting in
Baystate sells out, and it has been selling out earlier than the organizers expected. Once the marathon closes, a first come first served waitlist opens, and runners who get an offer have 48 hours to register. If a flat October race in New England is the target, put this one on your calendar for the week entries open rather than the month before.
Where does the Baystate Marathon get hard?
Mile 20 on the second lap, where the race itself posts 'The Wall', with the Rourke Bridge still to come at 22.5 and a short final climb waiting inside the last two miles.
What is the weather like at the Baystate Marathon?
Race morning in Lowell typically starts near 45F with humidity around 79% and a light northerly, climbing to an average high near 58F. That's close to ideal marathon weather, which is part of why the qualifying rate here is what it is. Train through some cold early mornings so a 45F start line doesn't cost you the first two miles fumbling with layers.
Is the Baystate Marathon a good Boston qualifier?
Baystate is a Boston eligible certified course and one of the more productive qualifiers in the country. 22.9% of finishers ran qualifying times in both 2025 and 2024, and 28.9% did in 2021. Its net elevation change of about 4 feet means no net downhill adjustment applies to a time run here.
Is the Baystate Marathon a good first marathon?
It works for a first marathon if flat and predictable is what you want, but go in knowing the room. With 22.9% of the 2025 field running qualifying times, you'll be surrounded by people chasing a number, and the marathon sells out well ahead of race day. The official site publishes no course time limit, so confirm the cutoff with the organizers before you enter.
Baystate Marathon questions, answered.
Is the Baystate Marathon flat?
Yes. The Baystate Marathon has about 507 feet of climbing across 26.2 miles and a net elevation change of roughly 4 feet, running between 75 and 143 feet above sea level along the Merrimack River. The only rises worth naming are a gradual hill near mile 2 and a quarter mile climb inside the final two miles.
Is Baystate a good Boston qualifier?
It's one of the better ones. 22.9% of Baystate Marathon finishers ran Boston qualifying times in 2025, matching 2024, and the rate has stayed above 22% every year since 2021. The course is flat, certified and Boston eligible, and its net elevation change of about 4 feet means no downhill adjustment applies.
What is it like running a double loop marathon?
Harder than it sounds. Baystate sends you back out for a second lap of the Merrimack at around mile 13, and the race marks 'The Wall' at mile 20 on that return. The scenery is already familiar by the time you're tired. Practice looping long runs back through your own start so the repeat feels normal.
How big is the Baystate Marathon?
Mid sized and growing. 1,140 runners finished the marathon in 2025, up from 938 in 2023 and 689 in 2021. That's large enough to find people running your pace on a flat course and small enough that the start isn't a twenty minute shuffle to the line.
Where does the Baystate Marathon get hard?
Mile 20 on the second lap, where the race itself posts 'The Wall', with the Rourke Bridge still to come at 22.5 and a short final climb waiting inside the last two miles.
