How do Boston qualifying times work?

The BAA sets a maximum finish time for each five-year age and gender group. You must run at or under that time on a certified course. Meeting the standard makes you eligible to apply, but it does not guarantee entry.

Why does meeting the standard not guarantee a spot?

When more qualified runners apply than there are spots, the BAA accepts the fastest applicants first, applying a cut-off below the official standard. In recent years that extra buffer has been several minutes, so aim to beat your standard by a margin.

Use your age on the date of the Boston Marathon you are entering, not the date of your qualifying race. The BAA bases your bracket on race-day age, which can move you into a more generous group if you have a birthday in between.

Does the course need to be certified?

Yes. Only times run on courses certified by a recognized governing body, such as USATF or World Athletics, count. Treadmill, virtual, and uncertified-course times are not accepted for Boston qualification.

What buffer should I target?

Because of the rolling cut-off in oversubscribed years, many coaches suggest beating your standard by at least three to five minutes to be safe. The checker shows your exact buffer so you can judge how much margin you have.

Do you have a BQ?

A Boston Qualifier, or BQ, is a marathon time at or under the Boston Athletic Association standard for your age and gender. This checker compares your finish time against the published standards and tells you not just whether you qualify, but by how much — the buffer that matters when entry is oversubscribed.

How it works

The BAA publishes a table of maximum finish times in five-year age brackets, separated by gender. The check is a direct comparison:

qualified = finish_time <= standard_for_bracket
buffer = standard_for_bracket − finish_time

Your bracket is determined by your age on race day. This tool uses the current BAA qualifying standards, which range from 3:00:00 for the youngest men’s bracket up to far more generous times for older athletes, with the women’s standards set 30 minutes more generous than the men’s in each bracket.

Tips and notes

A positive buffer means you cleared the standard; the larger it is, the safer you are if the BAA applies a rolling cut-off. In recent oversubscribed years, runners needed to beat their standard by several minutes to actually gain entry, so do not treat an exact-standard time as a sure thing.

Remember that only certified-course, chip-timed marathons count, and your age bracket is based on the Boston race date — a birthday between your qualifier and Boston can shift you into an easier standard.
