Hitting a Boston Qualifying time and getting into Boston are two different things. Since 2012 the BAA has run a rolling registration: the fastest qualifiers within each age group get in first, and a cutoff is set wherever applications meet the field size. The cutoff has grown from 0 seconds to 5+ minutes faster than the published standard in just over a decade.
Why the cutoff exists
Boston has roughly 30,000 spots. Charity bibs, sponsors, and elite/legacy entries consume around 5,000. That leaves ~25,000 time-qualifier spots. When more than 25,000 qualifiers apply, the slowest get cut — even though they hit the official BQ standard.
Cutoff times by year
Rolling registration started in 2012 and the cutoff has swung wildly ever since — from years where every qualifier got in to years where nearly seven minutes of buffer was the price of a bib.
2019–2026: the accepted cutoffs
- 2019: 4:52 under the standard
- 2020: 1:39 under the standard
- 2021: 7:47 under the standard
- 2022: no cutoff — every qualifier who applied was accepted
- 2023: no cutoff — every qualifier who applied was accepted
- 2024: 5:29 under the standard
- 2025: 6:51 under the standard
- 2026: 4:34 under the standard
If your BQ time is exactly the standard, plan as if you didn't qualify. Across 2019–2026 the accepted cutoff averaged 3:54 under the standard.
What 2027 will likely require
The 2026 race ran on the tightened standards, and the accepted cutoff still came in at 4:34. Nobody can publish the 2027 number before registration closes, so the defensible plan is to build the buffer the record supports: 5:00 under your standard, which is the larger of the most recent accepted cutoff and the five-year average.

How to actually beat the cutoff
- 01Target 5:00 under your standard — not the standard itself
- 02Pick a fast, certified course (Berlin, Chicago, CIM, Indianapolis Monumental, Erie)
- 03Train 18–20 weeks with a structured plan and at least one tune-up half marathon
- 04Run the race within the qualifying window for the year you want to enter
- 05If you qualify by a thin margin, register a backup race inside the same window
Questions athletes ask about this
- What was the Boston Marathon cutoff for 2025?
- The 2025 Boston Marathon cutoff was 6:51 under the official qualifying standard — the largest in race history. The BAA responded by tightening standards by five minutes for every age group under 60, starting with the 2026 race.
- What will the 2027 Boston Marathon cutoff be?
- It is not published until registration closes. The 2026 race required 4:34 and the five-year average is 3:23, so a 5:00 buffer is the planning number this record supports.
- How much faster than the BQ standard do I need to run?
- Plan on 5:00 under your age-group standard. The accepted cutoff has ranged from nothing at all to 7:47 in the last decade, so the buffer is insurance against a demand swing you cannot forecast.
- Why does Boston have a cutoff time?
- Boston has about 30,000 total spots. After charity, sponsor, and elite entries, roughly 25,000 are available to time qualifiers. When more than 25,000 qualifiers apply, the slowest are cut off — even if they hit the official BQ standard.
- What is the BQ standard for a 40-year-old man in 2027?
- The Boston qualifying standard for men 40–44 is 3:05:00 (women and non-binary 3:35:00). To actually register and get in, plan to run 3:00:00 or faster based on the cutoff history.
- When does Boston Marathon registration open?
- Boston Marathon registration typically opens in mid-September for the following year's April race. The qualifying window is roughly 18 months — qualifying times from September of two years prior through the close of registration are valid.
