Boston Marathon Qualifying Just Changed: 1,000 More Spots and a New Downhill Rule
Boston Marathon qualifying changed this year, and it changed in your favor. For the first time, running a qualifier and missing the cut-off does not end your year — the B.A.A. has added a random draw of roughly 1,000 entries reserved specifically for qualifiers who came up short of the buffer, and if you apply during registration week, you are in it automatically.
Registration for the 2027 Boston Marathon opens Monday, September 14, 2026 and closes at 5:00 p.m. ET on Friday, September 18. That is the near-term clock. The larger one starts the very next morning: the 2028 qualifying window opens Saturday, September 19, 2026, which makes this week the natural starting line for anyone building toward a qualifying attempt over the next twelve months.
Two things changed, and both reward athletes who understand them early. Here is how Boston Marathon qualifying works now.
Change One: Boston Marathon Qualifying Now Includes a Draw of About 1,000 Spots
The B.A.A. calls it the Boston Qualifier Selection. Roughly 1,000 qualifiers will be randomly selected for entry, drawn from applicants whose qualifying time was not faster than the cut-off for their age group and gender.
Three details matter:
You still need a legitimate qualifying time. The draw is not a general-entry lottery. The pool is made up of people who already ran a Boston qualifier and submitted an application.
There is no separate application. Apply during registration week and you are automatically eligible.
The result comes with your regular notification. The B.A.A. has not published a draw date — only that all applicants are notified of acceptance or non-acceptance by early October 2026.
Some scale for why this is genuinely good news. In 2026, the cut-off was 4:34 under the standard, and 8,887 qualified athletes were not accepted. The year before, the cut-off was 6:51 and 12,324 qualifiers missed out. Those are people who did the work, ran the time, and still went home. About a thousand of them now get a second path.
One correction worth making, because it is circulating: Boston has not eliminated qualifying times. Some coverage compressed "no change to qualifying times" into "no qualifying times." The standards are fully in force and unchanged.
Athlete Takeaway: If you have a valid qualifying time from the current window, apply during registration week even if you are behind last year's cut-off. Applying is what puts you in the draw.
Change Two: A Downhill Adjustment, and It Measures Something Specific
The second change adjusts submitted times from steeply net-downhill courses. This is the one most often described inaccurately, so the definition is worth getting exactly right.
The B.A.A. defines net-downhill as the difference in elevation between the start and finish points of an event. Not total descent. Not descent per mile. Start elevation minus finish elevation.
That distinction decides whether the rule touches you at all. A rolling course with thousands of feet of cumulative descent but a finish line near the same elevation as its start is unaffected. A point-to-point course that drops steadily from a mountain to a valley is the target.
Net elevation drop, start to finish | Adjustment to your submitted time |
1,500–2,999 ft (457.2 m – 914.1 m) | +5:00 added |
3,000–5,999 ft (914.2 m – 1,828.5 m) | +10:00 added |
6,000 ft (1,828.6 m) or greater | Not allowed for Boston qualifying |
It applies to times run in the qualifying window that opened September 13, 2025, and it is first applied at this September's registration. The B.A.A. has said it will be in place for at least the next two years.
The practical read: for the large majority of certified marathons, nothing changes. If you are choosing a race specifically for a fast qualifying time, course profile is now a real input into that decision rather than a matter of taste — and the honest version of that decision is to pick a course you can execute well, not the one with the steepest downhill.
Athlete Takeaway: Before you register for a qualifying race, check its start and finish elevations. If they are within about 1,500 feet of each other, the adjustment does not apply and you can plan your race normally.
The Boston Marathon Qualifying Standards Did Not Change
Confirmed for both 2027 and 2028: the qualifying standards are the same ones used in 2026. Age is as of race day.
Age group | Men | Women | Non-binary |
18–34 | 2:55:00 | 3:25:00 | 3:25:00 |
35–39 | 3:00:00 | 3:30:00 | 3:30:00 |
40–44 | 3:05:00 | 3:35:00 | 3:35:00 |
45–49 | 3:15:00 | 3:45:00 | 3:45:00 |
50–54 | 3:20:00 | 3:50:00 | 3:50:00 |
55–59 | 3:30:00 | 4:00:00 | 4:00:00 |
60–64 | 3:50:00 | 4:20:00 | 4:20:00 |
65–69 | 4:05:00 | 4:35:00 | 4:35:00 |
70–74 | 4:20:00 | 4:50:00 | 4:50:00 |
75–79 | 4:35:00 | 5:05:00 | 5:05:00 |
80 and over | 4:50:00 | 5:20:00 | 5:20:00 |
Meeting the standard makes you eligible to apply. The cut-off — how far under the standard you actually need to be — is set after registration closes, based on who applied. Nobody knows what it will be this year, and anyone who tells you otherwise is guessing.
Registration Week: What to Have Ready Before September 14
Applications are submitted through the B.A.A.'s Athletes' Village platform across five days, September 14–18. Applying early in the week carries no advantage over applying later — but a missing detail on Friday afternoon does carry a cost, so front-load it.
Your qualifying race, date, and official time, exactly as it appears in the official results.
Confirmation the race was certified and inside the window — times must come from the window that opened September 13, 2025.
Your Athletes' Village login, tested in advance rather than at 4:45 on Friday.
Your age on race day, April 19, 2027 — not your age today. If you move up an age group between now and then, that is the standard you are held to.
Athlete Takeaway: Block twenty minutes in the week of September 7 to gather your qualifying-race details and log into Athletes' Village once. Then registration week is a five-minute task.
The 2028 Window Opens September 19 — and That Is the Bigger Opportunity
This is the part most athletes miss. The day after 2027 registration closes, the 2028 qualifying window opens, running through 2028 registration week in September 2027. That is a full year of eligible races, and you get to choose where in it your best attempt lands.
A few things follow from that.
Fall and winter races count toward 2028, not 2027. Anything you run from September 19 onward is a 2028 qualifier. Two that our athletes ask about most:
Race | Date | Note |
Fort Worth Marathon | Sunday, November 8, 2026 | USATF-certified, BQ eligible. Registration closes September 7, 2026 |
Chevron Houston Marathon | Sunday, January 17, 2027 | Certified by the USATF Road Running Technical Council, so it qualifies runners for Boston |
A twelve-month window is a periodization opportunity, not a deadline. You do not need to chase a qualifying time at the next available race. You can build a genuine base block through the fall, sharpen over the winter, and arrive at one well-chosen marathon actually fit. Our guide to building your 2027 race schedule works through how to sequence that, and peak training done right covers the final weeks in detail.
The qualifying attempt is a pacing problem as much as a fitness problem. A qualifying time is a specific number, which makes even splits and honest early pacing worth more than they are in a race you are simply trying to finish. Our marathon pacing guide is written for the IRONMAN run, but the arithmetic of not spending your first ten kilometers travels intact — and the science of tapering covers arriving fresh enough to run the number you trained for.
If you are coming back to running volume after a triathlon season, returning to running after time off is worth reading before you start adding miles.
Athlete Takeaway: Pick one target qualifying race inside the 2028 window and one backup, then build a single periodized block toward the primary. One well-executed attempt beats three rushed ones.
How This Compares to Qualifying in Triathlon
Plenty of our athletes work both sides of the sport, and the two qualification systems are moving in interestingly different directions. IRONMAN rebuilt age-group qualification around age-graded performance for the 2026 cycle — we covered it in the Kona qualification rule change. Boston has gone the other way, keeping fixed time standards and adding a chance-based component on top.
The training implication is the same in both cases: a specific time on a specific day, produced on purpose. That is a coachable problem in either sport.
The Bottom Line
Boston Marathon qualifying is more forgiving in 2027 than it has been in years. About a thousand entries now go to qualifiers who missed the buffer, and you enter that draw simply by applying between September 14 and 18. The downhill adjustment affects a small number of steeply point-to-point courses and leaves most certified marathons untouched — check your race's start and finish elevations and move on.
Then look at September 19. A twelve-month qualifying window is the most generous planning runway in the sport, and the athletes who use all of it tend to be the ones who run the time.
If you want a season built around a specific qualifying attempt — the right race, the right block, the right target pace — set up a call with us now, and we will help you be ready for your best race day!
