A 59-year-old man needed 3:24:43 to get into the 2027 Boston Marathon. A 60-year-old needed 3:44:43.
Run both through the Alan Jones 2025 road age-grading tables and the 59-year-old's bar grades 71.6%. The 60-year-old's grades 65.9%. One birthday, 5.7 points. That's the biggest jump anywhere in the Boston table, and it's grown over the last two cycles.
The Boston Athletic Association (B.A.A.) announced the 2027 cutoff on 29 September 2026: 5:17 under your standard. The coverage I read turned that into "effective qualifying times" and stopped there. So I graded every one of them, at every age from 18 to 84.
What did it take to get into Boston 2027?
The time that got you into the 2027 Boston Marathon was your age-group standard minus 5:17. The B.A.A. received 33,649 qualifier applications in registration week, 14-18 September.
It accepted 24,630 of them on time and turned away 8,019 runners who had met their standard. Another 1,000 places went to the new Boston Qualifier Selection, a random draw among everyone who qualified but missed the cutoff (B.A.A., 2026-09-29).
The 2027 standards themselves didn't change from 2026 (baa.org, retrieved 2026-10-01). So the whole story this year is the cutoff.
Age-graded percentage divides the age-standard time for your exact age by your actual time. In the table below, the effective time is graded at the youngest and oldest age in each bracket. Youngest is where the flat time asks the most. Oldest is where it asks the least.
Men:
| Bracket | Standard | Effective time | AG% youngest | AG% oldest |

Women:
| Bracket | Standard | Effective time | AG% youngest | AG% oldest |
|---|---|---|---|---|
| 18-34 | 3:25:00 | 3:19:43 | 70.6% (18) | 65.7% (34) |
| 35-39 | 3:30:00 | 3:24:43 | 64.2% | 65.3% |
| 40-44 | 3:35:00 | 3:29:43 | 64.0% | 65.5% |
| 45-49 | 3:45:00 | 3:39:43 | 63.0% | 65.1% |
| 50-54 | 3:50:00 | 3:44:43 | 64.3% | 67.1% |
| 55-59 | 4:00:00 | 3:54:43 | 65.0% | 68.5% |
| 60-64 | 4:20:00 | 4:14:43 | 64.0% | 67.8% |
| 65-69 | 4:35:00 | 4:29:43 | 65.0% | 69.1% |
| 70-74 | 4:50:00 | 4:44:43 | 66.5% | 71.2% |
| 75-79 | 5:05:00 | 4:59:43 | 68.9% | 75.8% |
| 80+ | 5:20:00 | 5:14:43 | 74.3% (80) | — |
The B.A.A. also publishes a non-binary standard, identical to the women's column. The Alan Jones tables only have male and female factors, so there's nothing to grade it against. The 80+ bracket has no upper age, so it has no oldest edge either. I covered that open-ended case in the post on Boston's qualifying times by age.
Is the 5:17 cutoff the same size at every age?
No. Five minutes seventeen is a fixed amount of time, so it takes a bigger bite out of a fast standard than a slow one. Off the men's 2:55:00 it's 3.0% of the time. Off the women's 5:05:00 it's 1.7%.
Age grade scales with time, so the same thing happens in points. Graded at the youngest age in each bracket, the cutoff adds 2.2 points to what an 18-year-old man had to run. For a man of 80 it adds 1.2. The women's version runs from 1.8 points at 18 down to 1.2 from 70 up.
| Bracket (youngest age) | Men: % of time | Men: AG pts | Women: % of time | Women: AG pts |
|---|---|---|---|---|
| 18-34 (18) | 3.0% | 2.2 | 2.6% | 1.8 |
| 40-44 (40) | 2.9% | 2.0 | 2.5% | 1.6 |
| 50-54 (50) | 2.6% | 1.8 | 2.3% | 1.5 |
| 60-64 (60) | 2.3% | 1.5 | 2.0% | 1.3 |
| 70-74 (70) | 2.0% | 1.3 | 1.8% | 1.2 |
| 80+ (80) | 1.8% | 1.2 | 1.7% | 1.2 |
Chicago and NYC have the same issue with their flat qualifying times by age. None of this is a design flaw. A cutoff in minutes and seconds is easy to publish and easy to check against your watch. It just means "everyone needed 5:17 more" holds on the clock and comes apart on the age-grade scale. The youngest runners paid nearly twice as much as the oldest.
The cliff at 60
The effective Boston bar drops hardest at age 60, for both men and women. Plot the effective time at every single age and you get a sawtooth. From 35 up, inside a bracket the flat time grades the same or a little higher every year, because the age standard eases while the time doesn't. Then the next bracket's slower standard kicks in and the line drops. It's the problem with 5-year age groups, with a cutoff on top.
Every other drop is 0.8 to 3.7 points. The one at 60 is 5.7 points for men and 4.5 for women. A 59-year-old man had to run a race that grades 71.6%. A 60-year-old got in with 65.9%.
The cause is the standards themselves. Below 60, each bracket's standard is 5 or 10 minutes slower than the one before it. Above 60 the steps are 15 minutes. The step into 60-64 itself is 20: 3:30:00 to 3:50:00 for men, 4:00:00 to 4:20:00 for women.
What changed since the 2025 race?
The 60 cliff got bigger. In September 2024 the B.A.A. cut five minutes from every qualifying standard for runners under 60, starting with the 2026 race. Its reason was that it had been turning away athletes aged 18-59 "at the highest rate" (B.A.A., 2024-09-16). The standards for 60 and over stayed where they were.
Take the effective time for the 2025 race, the last one before that change, and compare it with 2027. The 2025 cutoff was 6:51 (B.A.A., 2024-09-24).
| Runner | 2025 race: standard − 6:51 | 2027 race: standard − 5:17 | Change |
|---|---|---|---|
| Man, 59 | 3:28:09 (70.4%) | 3:24:43 (71.6%) | 3:26 harder |
| Man, 60 | 3:43:09 (66.4%) | 3:44:43 (65.9%) | 1:34 easier |
| Woman, 59 | 3:58:09 (67.6%) | 3:54:43 (68.5%) | 3:26 harder |
| Woman, 60 | 4:13:09 (64.4%) | 4:14:43 (64.0%) | 1:34 easier |
The gap between the 59-year-old's bar and the 60-year-old's went from 15 minutes to 20. In age-grade terms the drop at 60 grew from 4.0 points to 5.7 for men, and from 3.2 to 4.5 for women. The other bracket edges barely moved.
The B.A.A. chose this. It decided to tighten under-60 and leave 60+ alone, based on who it was turning away. The result is that for 2027, one of the easiest bars in the men's table sits one birthday after one of the hardest.
Does Boston now ask for 70%?
For men under 60, at the top of every bracket, yes. In the original post on Boston qualifying times I said a Boston standard rarely gets past 70%, the line RaceRecords calls local class. That was true of the published standard. It isn't true of the time that actually got people in.
Graded at the oldest age in each bracket, the 2027 effective time for men from 18 to 59 grades between 70.0% and 71.7%. At the youngest age it's 67.8% to 69.1%, plus the 18-year-old edge at 73.4%. From 60 to 74 nothing reaches 70%.
Women's effective times stay under 70% at every age from 19 to 73. Above that they clear it at 74 and at every age from 76 up, reaching 75.8% at 79 and higher again in the open 80+ bracket.
So "BQ'd and got in" is a strong age-graded race for a man of 44 or 54: 71.0% and 71.7%. The published standard alone asked 68.9% and 69.8% of them. It's not yet 80% national class, but the cutoff pushed both over the line.
Is the 1,000-place draw fair by age?
The Boston Qualifier Selection is neutral by age, which isn't the same as fair. Anyone who met their standard but missed the 5:17 cutoff went into the Boston Qualifier Selection automatically. The B.A.A. describes it as a random selection and mentions no weighting by age or by how close you came (B.A.A., 2026-07-22).
8,019 qualifiers were still left out after the draw, so about 9,000 were in it for 1,000 places. That's roughly 1-in-9.
Take two 40-year-old men in that pool. One ran 3:04:59, a second under standard, which grades 66.6%. The other ran 2:59:44, a second short of the cutoff, which grades 68.6%. Two age-grade points apart, same ticket.
That's a reasonable choice for a lottery. A draw that rewarded margin would just be a softer cutoff. Still, the draw can't fix anything the flat cutoff does by age. It doesn't try to.
What this means for a 2028 BQ
The 2028 Boston qualifying standards are already set. The B.A.A. says the 2028 qualifying times are the same as 2027's (B.A.A., 2026-07-22), and the qualifying window opened on 19 September 2026 (B.A.A., 2026-09-29).
The cutoff won't be known until after registration closes next September. Over the last four races it's been 5:29 (B.A.A., 2023), 6:51, 4:34 (B.A.A., 2025) and now 5:17.
So the honest planning number is the standard minus five to seven minutes. If you're running on a steep course, the downhill index comes on top of that.
And if you'll be 60 on race day, the arithmetic is on your side by a margin nobody earned. If you'll be 59, it isn't. Either way, the clock decides the entry. The age grade is still the better measure of the race.
If you want that measure for your own marathon, run it through the age-grade calculator.

Every age grade here is a B.A.A. standard, minus the published cutoff, divided into the Alan Jones 2025 age-standard time for that exact age. Those tables standardise the men's marathon on 2:00:35. If the next revision adopts Sawe's 1:59:30 from London in April 2026, every men's figure here drops slightly.
