How this works

These are the Boston Athletic Association qualifying standards for the 2026 and 2027 Boston Marathons, which were tightened by five minutes for athletes under 60 versus the 2020–2025 set. Your standard is set by your age on race day and your sex; non-binary athletes currently use the women’s standard.

Because more people qualify than there are spots, the BAA accepts the fastest applicants first. The real acceptance line — the “cutoff” — has run about 4:34 to 6:51 under the standard in recent non-COVID years. We use a 6:00 planning buffer as a realistic target.

Only a BAA-certified, record-eligible marathon counts — time trials, virtual races, and uncertified courses don’t qualify no matter how fast the watch reads. Registration typically opens in September for the following April’s race, and it’s rolling: the fastest qualifiers relative to their own standard get in first, and the field can close before every qualified runner who applied gets a spot. That’s the actual mechanism behind the cutoff, and why treating your BQ time as a minimum bar rather than a target is the safer way to train for it.

Qualifying is a training problem
The hard part

Knowing your BQ time is easy. Building the fitness to run it, on a day you can’t choose, with a buffer, is the actual work — and it needs the right blend of long runs, threshold, and taper timed to your race.

How Vertical helps

Vertical builds an adaptive marathon plan around your BQ target and your real training data, adjusts when life gets in the way, and tells you honestly whether your buffer is on track — every week, all the way to race day.
