This page covers the cutoff, how it compares with past years, and what changes for Florida runners chasing a BQ.
What is the 2027 Boston Marathon cutoff?
The 2027 Boston Marathon cutoff is 5:17. Qualifiers who ran 5 minutes, 17 seconds or more under their age-group standard were accepted, the B.A.A. announced on September 29, 2026. A record 25,630 qualifiers got in, including about 1,000 picked at random from runners who missed the cutoff. The 2026 cutoff was 4:34.
The key dates
| Date | What happens |
|---|---|
| Sept 14-18, 2026 | Qualifier registration week (closed) |
| Sept 19, 2026 | Qualifying window for the 2028 Boston Marathon opens |
| Sept 29, 2026 | Cutoff announced (5:17); acceptance and non-acceptance notices go out |
| April 19, 2027 | 131st Boston Marathon |
Past Boston cutoffs
The cutoff moves every year with the size of the field and how many people qualify. Here is how the last nine races went.
| Race year | Cutoff under standard |
|---|---|
| 2027 | 5:17 (plus about 1,000 runners drawn at random) |
| 2026 | 4:34 (first year of the faster standards) |
| 2025 | 6:51 |
| 2024 | 5:29 |
| 2023 | 0:00 (everyone who qualified got in) |
| 2022 | 0:00 |
| 2021 | 7:47 (smaller October field) |
| 2020 | 1:39 |
| 2019 | 4:52 |
The 2026 number looks friendlier than 2025, but it is not. The B.A.A. made every standard from age 18 to 59 five minutes faster for 2026, so a 4:34 cutoff on the new standards is harder to beat than 6:51 on the old ones.
What is new for 2027
A random draw for runners who miss the cutoff
For the first time, the B.A.A. picked about 1,000 extra runners at random from qualifiers whose times were not fast enough to beat the 5:17 cutoff. It is called the Boston Qualifier Selection. Every qualifier who registered and missed the cutoff was in that pool automatically, and the B.A.A. is notifying the runners it picked by email.
A penalty for steep downhill courses
Qualifying times run on courses that drop a lot of elevation now get time added before they are ranked:
- 1,500 to 2,999 feet of net drop: 5 minutes added
- 3,000 to 5,999 feet: 10 minutes added
- 6,000 feet or more: not accepted for qualifying
The B.A.A. says the rule stays in place for at least the next two years. That matters for the runners who chase BQs on mountain courses out west. It does not matter in Florida. The highest point in the state is about 345 feet, so no Florida marathon comes anywhere near a 1,500-foot drop. A BQ on the Space Coast counts the same as it always has.
The current qualifying standards
These apply to the 2027 race and carry over to 2028 unless the B.A.A. says otherwise.
| Age group | Men | Women and 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 |
