How it works
qualified if marathon time ≤ B.A.A. standard for your age band and gender
Qualifying is a straight comparison: your net time against the published standard for your five-year age band and gender, with age counted on Boston race day rather than the day you qualified. The 2026 standards this tool checks start at 2:55:00 for men aged 18–34 and 3:25:00 for women and non-binary athletes in that band, ease to 3:00:00 and 3:30:00 at 35–39, and keep relaxing with each older band up to 80+; every standard tightened by five minutes for athletes under 60 beginning with the 2026 race. The margin is what the calculator really emphasizes, because oversubscribed years bring a cutoff below the standard — the fastest applicants fill the field first. Recent cutoffs ran 5:29 for 2024, 6:51 for 2025 (a year that turned away 12,324 qualifiers), and 4:34 for 2026, so any margin under roughly five minutes gets flagged as still at risk.

Announced cutoffs under the standard: 2024 = 5:29, 2025 = 6:51, 2026 = 4:34 (the 2025 race rejected 12,324 qualifiers). Meeting the standard is necessary but not always sufficient.

FAQ
What time do I need to qualify for Boston?
It depends on your age band and gender on race day. Under the 2026 standards, men aged 18–34 must beat 2:55:00 and women in that band 3:25:00, with roughly five extra minutes allowed for each older five-year band. Enter your details and the calculator pulls the exact standard for you.
Which age do I enter — my age now or on race day?
Your age on the day of the Boston Marathon you want to run, not your age when you race the qualifier. Runners who move up a band before Boston are judged against the older, slower standard — sometimes enough to flip a near miss into a BQ. The tool uses whatever age you enter.
Why does the tool warn me even though I beat the standard?
Because beating the standard only earns the right to apply. For 2025 the effective bar sat 6 minutes 51 seconds under the published times and 12,324 qualifiers were refused; 2024 required 5:29 and 2026 required 4:34. Any margin under about five minutes gets flagged here for exactly that reason.
Did the standards change recently?
Yes — starting with the 2026 race, the B.A.A. cut five minutes from every standard for athletes under 60, partly to shrink the cutoff. It worked to a degree: the cutoff dropped from 6:51 (2025) to 4:34 (2026). This calculator already compares against the tightened 2026 times.
How big a buffer should I actually aim for?
Recent cutoffs suggest at least five to seven minutes under your standard. Practically, an 18–34 man should train toward 2:50 rather than 2:55, and an 18–34 woman toward 3:20 rather than 3:25. Since the cutoff is announced only after registration closes, extra buffer is never wasted.
Does any marathon count as a qualifier?
No — it must be a certified, in-person, full-distance marathon, and the B.A.A. goes by net (chip) time. Virtual events and uncertified courses do not count. Before building a season around a BQ attempt, confirm the race you have in mind runs on a certified course.
How are non-binary athletes and age bands handled?
Non-binary runners are assessed against the standards listed for women under current B.A.A. policy, and this tool applies the same rule. Bands span five years — a 40-year-old and a 44-year-old face the same mark — so your standard only shifts when you cross into a new band.
When do I register, and which races fall in the qualifying window?
Registration opens in September, about seven months before the April race, and your qualifier must land inside the B.A.A. qualifying window — typically from early September two years out through the close of registration. A spring marathon the year before Boston counts, and so does an early-fall race right before you apply; exact window dates are published at baa.org each cycle.
The B.A.A. owns and periodically revises these standards and cutoffs; the times checked here are the published 2026 qualifying marks, last reviewed June 2026. Meeting a standard is an application threshold, not an entry guarantee — verify the latest rules at baa.org before planning a season around a BQ.
