Boston Marathon Qualifying Times, Decoded

Running a Boston qualifier used to be the whole job. You hit the time on your age-group chart, sent in the application and started looking at hotels in Back Bay. That version of Boston ended a while ago. In each of the last four registration cycles the qualifying standard has bought an application rather than a bib, and for the 2027 race, 8,019 runners who beat their standard were still turned away (B.A.A.).

So there are two numbers to know: the standard printed on the B.A.A.’s chart, and the cutoff that registration week reveals underneath it. This guide covers both, the pace each one asks of you, and the rules that quietly void times runners thought were safe.

The qualifying standards for 2027 and 2028

The B.A.A. uses the same standards for the 2027 and 2028 races (B.A.A.). Your age group is set by how old you’ll be on race day, not on the day you run the qualifier, which for the 2028 race means April 17, 2028. Times are net (chip) times, and the non-binary standards match the women’s.

These standards got five minutes tighter for everyone under 60 ahead of the 2026 race (B.A.A.). The 60-and-over standards stayed where they were.

Why a BQ doesn’t guarantee a bib

The race has about 30,000 official entrants, and charity, invitational, professional and Para entries fill the places qualifiers don’t (B.A.A.). Registration isn’t first-come, first-served. Everyone who applies during the single September registration week is ranked by how far under their standard they ran, and the B.A.A. accepts from the biggest margin down until the qualifier places are full (B.A.A.).

The margin where the places run out is the cutoff, and it’s one number applied to every age group and gender. For 2027, 33,649 qualifiers applied, and getting in on time alone took a result 5:17 faster than your standard (B.A.A.). A 42-year-old man with a 3:05 standard needed 2:59:43. A 3:01 would have been a BQ, would have felt like one in the finish chute, and still would have come up short.

How the cutoff has moved

Two patterns stand out. The B.A.A. has tightened the standards three times, before the 2013, 2020 and 2026 races, and each time the cutoff dropped that year before climbing again. And apart from the pandemic-delayed 2021 race, the three largest cutoffs on record all came in the last four cycles: 6:51 for 2025, 5:29 for 2024 and 5:17 for 2027 (Marathon Handbook).

The practical read is that a margin of exactly five minutes would have missed in three of the last four years. After the 2024 cutoff, many runners who wanted Boston started aiming for five to ten minutes under rather than just under (Running with Rock).

The Boston Qualifier Selection

For 2027, the B.A.A. added a random draw for qualifiers who beat their standard but miss the cutoff. There’s no separate application: if your margin falls short, you’re entered automatically, and about 1,000 runners are drawn (B.A.A.). In its first year, 24,630 runners got in on the cutoff and 1,000 more through the draw (B.A.A.). With roughly 9,000 runners in the pool, that worked out to about a one-in-nine chance (Marathon Handbook).

That’s a real lifeline if you’re a minute short, and a poor plan if you’re counting on it. Treat the draw as a bonus and train as though it doesn’t exist.

What pace a BQ actually takes

Pace per mile, with pace per kilometer in parentheses. The margin columns use the 2027 cutoff of 5:17.

The table assumes exactly 26.2 miles. Courses are measured along the shortest possible line, which almost nobody runs, so your watch will usually read long by the finish. If you pace off the watch, run a few seconds per mile faster than the table to cover that extra distance.

How you spend the pace matters as much as the number. In Strava’s analysis of 2022 fall marathons, running a negative split was the strongest predictor of hitting a BQ, stronger than a course’s elevation (Outside). Time banked in the first half tends to get paid back with interest in the second.

The rules that void good times

The course has to be certified. Your qualifier has to be a full marathon on a course certified by USATF, AIMS or the governing body of the country it’s in, run outdoors with transponder timing. Virtual, indoor and treadmill marathons don’t count, and neither do time trials (B.A.A.). Most big road marathons are certified, but smaller races and trail marathons often aren’t, so check before you register rather than after you finish.

Net-downhill courses carry a penalty. For times run on or after September 13, 2025, the B.A.A. adds five minutes to results from courses that drop 1,500 to 2,999 feet and ten minutes for drops of 3,000 to 5,999 feet, and it doesn’t accept courses that drop 6,000 feet or more (World Marathon Majors). The change followed a review of qualifying times since 2022 that found a significant advantage from big elevation drops. In the first cycle under the rule, 240 accepted runners had their times adjusted (Marathon Handbook), and the B.A.A. has said the indexes may change before 2028 registration (B.A.A.).

The window is fixed. For the 2028 race, the qualifying window opened September 19, 2026 and stays open through 2028 registration week in September 2027 (B.A.A.). A qualifier you ran in spring 2026 counted toward 2027 and can’t carry over.

Times get verified. The B.A.A. checks every submitted time against official results, which can take several days (B.A.A.).

Choosing a race to qualify on

Fast, flat courses with manageable fields produce far more qualifiers. In the same Strava analysis, 32% of finishers at CIM and Valencia ran a BQ, against 18% at Chicago and Berlin and about 6% at New York and the Marine Corps Marathon (Outside). Some of that is self-selection, since runners chasing a time pick CIM for exactly that reason, but course, weather and crowding all show up in the results.

Closer to home for Triangle runners, FindMyMarathon’s latest results put Tobacco Road in Cary at a 12.43% BQ rate, Wilmington at 11.26% and the RDC Marathon in Durham at 9.78%, while Raleigh’s hilly City of Oaks sits at 3.37% (FindMyMarathon). Any of them counts for 2028 if it falls inside the window.

Once a qualifier becomes the goal, it’s your A race, and the rest of the season should serve it. Building a Better Race Calendar covers how to keep the races around it from eating into it.

Train for the margin, not the standard

The standard is a pass mark, and the cutoff is the grade that’s been getting in. That changes what you train for. If your standard is 3:30, a realistic target for 2028 is somewhere around 3:23 to 3:25, and the fitness for that has to exist before race day rather than show up on it.

The Strava data gives a sense of what that fitness looked like. Runners who qualified at CIM peaked around 65 miles a week, against about 50 for the rest of the field, and at Chicago the split was 57 against 41 (Outside). The same analysis found that runners who kept their easy days about 30% slower than goal pace hit their goals more often than those who ran easy days only 10% slower. Both findings point the same way: more aerobic volume, run properly easy, with the hard work saved for the days built for it. The Easy Run and The Long Run Decoded cover the volume side, and tempo running is where the threshold work lives.

If you keep landing a few minutes short, Greg McMillan’s advice for runners in that spot is to stop chasing the BQ for a cycle and work on getting faster first (McMillan Running). A block aimed at the 5K or half marathon raises the ceiling your marathon pace sits under. When you’re ready for the marathon block itself, How to Choose a Marathon Training Plan compares Higdon, Pfitzinger and FIRST side by side, and Trust the Work covers the taper and race week.

Other ways to the start line

Charity. A record 215 nonprofits received entries for 2027. Each charity sets its own fundraising minimum, commonly $10,000 at larger organizations such as Boston Children’s Hospital and Mass General Brigham, and each runs its own application timeline rather than going through the B.A.A. (Marathon Handbook). Charity runners raised a record $57.3 million for the 2026 race.

The draw. If you qualify and miss the cutoff, you’re automatically in that year’s Boston Qualifier Selection.

The next window. A qualifier run in spring 2027 counts for 2028, so a miss in September doesn’t waste the fitness you built.

The 2028 timeline

• September 19, 2026: the 2028 qualifying window opens.

• April 19, 2027: the 2027 race. The B.A.A. will announce 2028 registration details after it.

• September 2027: registration week. The qualifying window closes when it does.

• Early October 2027: acceptances and the cutoff, if the 2027 timing holds.

• April 17, 2028: race day.

FAQ

What is the Boston qualifying time for my age?

It depends on your age on race day and your gender. For the 2027 and 2028 races, the 18–34 standard is 2:55:00 for men and 3:25:00 for women and non-binary runners, and each older age group gets more time. The full chart is at the top of this page.

What was the 2027 Boston Marathon cutoff?

5:17. Qualifiers had to run 5 minutes and 17 seconds faster than their standard to be accepted on time, and about 1,000 more were added through the Boston Qualifier Selection.

Is the Boston qualifying time chip time or gun time?

Net (chip) time, from when you cross the start mat to when you cross the finish.

Do half marathon times count toward a BQ?

No. Only a full marathon on a certified course counts.

Can I still qualify for the 2028 Boston Marathon?

Yes. The window opened September 19, 2026 and runs through registration week in September 2027, so fall 2026, spring 2027 and summer 2027 marathons all count.

What happens if I qualify on a downhill course?

If the course drops 1,500 feet or more from start to finish, the B.A.A. adds five or ten minutes to your time, depending on the size of the drop. Courses that drop 6,000 feet or more can’t be used at all.
