How it works
qualified if marathon time ≤ B.A.A. standard for your age band and gender
The B.A.A. publishes a qualifying time for each five-year age band and gender, based on your age on race day. Your margin is the standard minus your finish time: run faster than the standard and you have a positive margin (a qualifier); run slower and you are over. Recent Bostons have been so popular that even qualifiers are cut by a “cutoff” — in some years runners needed to beat the standard by several minutes to be accepted. This tool treats a margin under about five minutes as a cutoff risk, so it flags whether you are comfortably clear, qualified-but-vulnerable, or short of the standard. The standards here reflect the current B.A.A. times, which were lowered by five minutes for athletes under 60 beginning with the 2026 Boston Marathon. ### Boston Marathon qualifying standards (B.A.A. 2026) | Age band (on race day) | Men | Women / Non-binary | | --- | --- | --- | | 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 | These are the exact times this calculator checks against. Non-binary athletes use the women’s standards under current B.A.A. policy. ### Recent Boston cutoff by year When more runners qualify than there are spots, the B.A.A. accepts the fastest first, so an extra “cutoff” buffer applies below the published standard. Recent years: | Boston Marathon | Cutoff under the standard | | --- | --- | | 2023 | 0:00 (all qualifiers accepted) | | 2024 | 5:29 | | 2025 | 6:51 | | 2026 | 4:34 | The cutoff is announced only after registration closes and varies year to year, so treat these as guidance, not a guarantee — which is why a comfortable buffer under the standard matters.

- Recent registration cutoffs (2024–2026) When applications exceed the field size, the B.A.A. accepts the fastest qualifiers first, so a “cutoff” below the standard applies. 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
How do I qualify for the Boston Marathon?
Run a certified marathon in under the B.A.A. standard for your age and gender, where your age is taken as of the Boston race day. Times must come from an officially measured, in-person marathon. Meeting the standard lets you apply, but acceptance depends on the year’s cutoff.
What is the Boston Marathon cutoff?
When more people qualify than there are spots, the B.A.A. admits the fastest applicants first, so a cutoff below the official standard can apply. In recent years it has ranged from a couple of minutes to nearly seven. That is why this calculator warns you if your margin is small.
What was the Boston Marathon cutoff in 2025?
The 2025 Boston Marathon cutoff was 6 minutes 51 seconds under the standard — the largest yet — and 12,324 runners who met their qualifying time were still turned away. For comparison, the 2024 cutoff was 5:29 and the 2026 cutoff was 4:34. Because the cutoff is set only after registration closes, beating the standard by a wide margin is the only real protection.
Did Boston qualifying get harder for 2026?
Yes. The B.A.A. lowered every qualifying standard by five minutes for athletes under 60 beginning with the 2026 Boston Marathon, so the bar to apply is tougher. The aim was to reduce the cutoff buffer, and it partly worked: the 2026 cutoff fell to 4:34 under the standard, down from 6:51 for 2025 — but you must now hit a faster standard first. This calculator already uses the 2026 standards.
How much under the standard should I aim to be?
Given recent cutoffs of 4:34 to 6:51 under the standard, aim to beat your qualifying time by at least five to seven minutes, and more if you can. A 18–34 man should target roughly 2:50 rather than 2:55, and a woman in that band roughly 3:20 rather than 3:25. This tool flags any margin under about five minutes as a cutoff risk.
Which age is used for qualifying?
Your age on the date of the Boston Marathon you are applying for — not your age when you ran the qualifying race. If you move up an age band before Boston, you are held to the standard for that older band, which is usually slightly more generous.
Do all marathons count for qualifying?
Only certified, full-distance marathons run in person count. Virtual marathons, indoor marathons and anything short of 26.2 miles are not accepted. Check that your goal race is on a certified course before targeting a BQ there.
Are the standards the same for everyone in an age band?
Yes — the standard is fixed for each five-year band and gender, so a 40-year-old and a 44-year-old face the same time. Non-binary athletes use the women’s standards under the current B.A.A. policy.
