Quick answer: Boston Marathon qualifying times have gotten dramatically harder since the first standard in 1970, when men simply needed to break 4 hours. Today’s standards are roughly an hour faster across every age group, and even hitting the published time often isn’t enough. Since 2013, the B.A.A. has required most qualifiers to beat their standard by an extra cutoff buffer, which has ranged from under 2 minutes to a brutal 7:47 in 2021.
Key takeaways:
Every serious marathoner has heard the phrase “run a BQ.” Fewer know how much that phrase has actually changed over more than five decades. This is the full year-by-year history. Updated August 2026.

Boston introduced qualifying times in 1970 because it had to. The race’s field had grown from 197 runners in 1960 to over 1,300 by 1969, and organizers needed a way to keep the event manageable. The original standard was simple: men needed to certify they could finish in under 4 hours. There was no separate women’s standard, since women weren’t officially permitted to enter until 1972, when they were given their own 3:30 standard.
That first 4:00 standard looks almost unrecognizably generous today. It reflects how different competitive distance running was in 1970, before the running boom of the 1970s and 80s reshaped the sport entirely.
The running boom of the 1970s did to Boston’s qualifying standard what it did to the sport at large: it forced rapid tightening. By 1980, the open men’s standard had dropped all the way to 2:50, a brutal cut from the original 4:00 in just one decade.
Through the 1980s and 90s, standards were adjusted repeatedly by age group, generally settling into the “5 minutes per decade of age” structure that still roughly holds today, where each 5-year age bracket earns a modest amount of extra time.
For decades, hitting the published qualifying standard was enough. That changed in 2011, when the race’s registration period sold out in just 8 hours, locking out runners who had legitimately qualified but registered too late. The backlash forced real reform.
The B.A.A.’s response had two parts: a 5-minute tightening of standards across every age group, and a rolling registration system that gave the fastest qualifiers first access. That second change is what created the modern “cutoff” era.
Starting with the 2014 race, hitting your exact qualifying standard stopped being a guarantee. Because the field is capped at roughly 30,000 runners and more people qualify than there are spots, the B.A.A. now accepts the fastest qualifiers relative to their standard first, working down until the field fills. The gap between the published standard and the actual time needed to get in is called the cutoff.
That cutoff has swung wildly depending on demand. It was a modest 1:38 for the 2014 race. It climbed to 4:52 by 2019. The pandemic-shrunk 2021 field pushed it to a record 7:47. Demand eased enough in 2022 and 2023 that every single qualifier was accepted, a 0:00 cutoff. Then demand surged again: 5:29 for 2024, and a brutal 6:51 for 2025, the number that finally pushed the B.A.A. to tighten the standards themselves for 2026.
The cutoff is how much faster than your age-group standard you needed to run to actually get accepted, not just qualify.
| Race Year | Cutoff Buffer | Context |
|---|---|---|
| 2014 | 1:38 | First year of the modern rolling cutoff system |
| 2019 | 4:52 | Demand climbing steadily pre-pandemic |
| 2020 | 1:39 | Race ultimately cancelled due to COVID-19 |
| 2021 | 7:47 | Record cutoff, pandemic-shrunk field size |
| 2022 | 0:00 | Every qualifier accepted, demand had dipped |
| 2023 | 0:00 | Every qualifier accepted again |
| 2024 | 5:29 | Demand surged back above field capacity |
| 2025 | 6:51 | Second-highest cutoff on record |
| 2026 | 4:34 | First year under the tightened 2026 standards |
The pattern is clear even with the swings: outside of the two anomaly years when every qualifier got in, the practical target has consistently been “beat your standard by several minutes,” not just meet it.
For 2026 and 2027, the B.A.A. cut standards by 5 minutes across nearly every age and gender group under 60, the largest single tightening since 1990.
| Age Group | Men | Women |
|---|---|---|
| 18-34 | 2:55:00 | 3:25:00 |
| 35-39 | 3:00:00 | 3:30:00 |
| 40-44 | 3:05:00 | 3:35:00 |
| 45-49 | 3:15:00 | 3:45:00 |
| 50-54 | 3:20:00 | 3:50:00 |
| 55-59 | 3:30:00 | 4:00:00 |
| 60-64 | 3:50:00 | 4:20:00 |
| 65-69 | 4:05:00 | 4:35:00 |
| 70-74 | 4:20:00 | 4:50:00 |
| 75-79 | 4:35:00 | 5:05:00 |
| 80+ | 4:50:00 | 5:20:00 |

The historical pattern isn’t just trivia. It’s a direct argument for training toward a buffer, not the bare minimum. Only twice in the last decade-plus has hitting the exact standard been enough. Every other year required beating it by anywhere from about a minute and a half to nearly 8 minutes.
Practically, that means treating your real target as “standard minus 5 minutes” rather than the published number itself. Our guide to training for your fastest marathon covers how to actually build toward that.
What was the very first Boston Marathon qualifying time?
A sub-4:00 finish for men, introduced in 1970. Women weren’t given an official standard until 1972.
Why did Boston introduce a cutoff buffer instead of just accepting everyone who qualifies?
After the 2011 registration sold out in 8 hours and locked out qualified runners, the B.A.A. introduced rolling registration that accepts the fastest qualifiers relative to their standard first.
Has the cutoff buffer ever been zero?
Yes, in 2022 and 2023, when post-pandemic demand had dipped enough that every runner who met the published standard was accepted.
How much faster than the standard should I actually train for?
Based on the last decade of cutoffs, aiming for roughly 5 minutes faster than your official standard is a realistic buffer in most years.
