Boston Marathon Qualifying Times 2028: The 5:17 Cutoff, the New Lottery & Your Real Target
Meeting the BQ standard doesn't guarantee a spot, and for 2027 the BAA added a lottery for the runners who miss. Here's how entry actually works now and what time you really need.
Running a Boston Qualifying time is one of the most celebrated achievements in distance running. But here's what most runners don't realize until it's too late: meeting the BQ standard doesn't guarantee you a spot on the starting line in Hopkinton.
Since 2012, the Boston Athletic Association has used a cutoff system that goes beyond the published qualifying times. Understanding this system is the difference between celebrating your acceptance email and wondering why your BQ wasn't enough.
How the Boston Cutoff Actually Works
The Boston Marathon has a field limit of approximately 30,000 runners. Around 24,000 of those spots go to time qualifiers. The rest are reserved for charity runners, sponsors, and invited athletes.
Here's the problem: far more than 24,000 runners achieve qualifying times each year.
When applications exceed available spots, the BAA ranks all applicants by how much faster they ran than their age and gender qualifying standard. They accept runners starting with the fastest buffers until the field is full. The last person accepted determines the cutoff.
For the 2027 Boston Marathon, 33,649 runners applied with valid qualifying times. The cutoff landed at 5 minutes and 17 seconds under the qualifying standard, which accepted 24,630 of them. A further 1,000 were admitted through a new random draw, described below.
That still left 8,019 runners who technically "qualified" for Boston without a place.
Historical Cutoff Data
The cutoff has varied dramatically over the years based on field size, number of qualifiers, and external factors like the pandemic.
| Year | Cutoff | Qualifiers Rejected |
|---|---|---|
| 2012 | 1:14 | 3,228 |
| 2014 | 1:38 | 2,976 |
| 2015 | 1:02 | 1,947 |
| 2016 | 2:28 | 4,562 |
| 2017 | 2:09 | 2,957 |
| 2018 | 3:23 | 5,062 |
| 2019 | 4:52 | 7,384 |
| 2020 | 1:39 | 3,161 |
| 2021 | 7:47 | 9,215 |
| 2022 | 0:00 | 0 |
| 2023 | 0:00 | 0 |
| 2024 | 5:29 | 11,039 |
| 2025 | 6:51 | 12,324 |
| 2026 | 4:34 | 8,887 |
| 2027 | 5:17 | 8,019 |
A few things stand out from this data.
The 2021 cutoff of 7:47 was the highest ever, but that year was an outlier. The field was reduced to 20,000 due to COVID restrictions, making competition especially fierce.
In 2022 and 2023, every qualifier who applied was accepted. This was partly because the field size returned to 30,000, but also because fewer runners had opportunities to run qualifying races during the pandemic years.
Since 2024, every cutoff has landed between four and seven minutes. The running boom is real, and more people are running faster than ever. The 2027 figure of 8,019 rejected qualifiers is also the first that understates the squeeze, because it counts the 1,000 runners rescued by the new lottery.
Current Qualifying Standards
In September 2024, the BAA tightened qualifying standards by 5 minutes for runners aged 18-59. Standards for runners 60 and older remained unchanged. These are still the standards in force.
The 2027 qualifying window has closed. If you are chasing Boston now, you are chasing the 2028 race, and the window for it opened on September 19, 2026.
Men
| Age Group | Qualifying Time |
|---|---|
| 18-34 | 2:55:00 |
| 35-39 | 3:00:00 |
| 40-44 | 3:05:00 |
| 45-49 | 3:15:00 |
| 50-54 | 3:20:00 |
| 55-59 | 3:30:00 |
| 60-64 | 3:50:00 |
| 65-69 | 4:05:00 |
| 70-74 | 4:20:00 |
| 75-79 | 4:35:00 |
| 80+ | 4:50:00 |
Women
| Age Group | Qualifying Time |
|---|---|
| 18-34 | 3:25:00 |
| 35-39 | 3:30:00 |
| 40-44 | 3:35:00 |
| 45-49 | 3:45:00 |
| 50-54 | 3:50:00 |
| 55-59 | 4:00:00 |
| 60-64 | 4:20:00 |
| 65-69 | 4:35:00 |
| 70-74 | 4:50:00 |
| 75-79 | 5:05:00 |
| 80+ | 5:20:00 |
These are the standards you must meet to apply. But based on recent trends, you'll likely need to beat them by 4-7 minutes to actually get in.
What This Means for Your Target Time
Let's do the math for a few common scenarios.
Male, age 40-44
- BQ standard: 3:05:00
- Recent cutoffs: 4:34 to 6:51 under
- Safe target: 2:58:00 or faster
Female, age 35-39
- BQ standard: 3:30:00
- Recent cutoffs: 4:34 to 6:51 under
- Safe target: 3:23:00 or faster
Male, age 18-34
- BQ standard: 2:55:00
- Recent cutoffs: 4:34 to 6:51 under
- Safe target: 2:48:00 or faster
The "safe target" assumes you want high confidence of acceptance. If you're comfortable with some uncertainty, you might aim for 5 minutes under your BQ standard. But anything less than 5 minutes under is risky based on recent data, and under 4 minutes has missed every cutoff since 2023.
New for 2027: The Boston Qualifier Selection
For the first time, missing the cutoff is no longer an automatic rejection. Alongside the 24,630 runners accepted on time for 2027, the BAA randomly selected 1,000 more from the pool of applicants who did not beat 5:17.
Roughly 9,000 qualifiers missed the cutoff, so the draw worked out to about a one in nine chance. That is not a plan, but it is no longer zero, and it changes how you should read a near miss.
The practical effect is that the cutoff has become a threshold with a soft edge rather than a wall. Beat it and you are in. Miss it narrowly and you are in a lottery you did not have to enter. The BAA has not said whether the draw will return in future years, so plan on beating the cutoff and treat the lottery as a consolation rather than a strategy.
Downhill Course Adjustments Are Now In Effect
The 2027 cycle was also the first to apply time penalties for races with significant net elevation drop. This is live, not upcoming.
- 1,500 to 2,999 feet drop: +5 minutes added to your time
- 3,000 to 5,999 feet drop: +10 minutes added to your time
- 6,000+ feet drop: Not eligible for Boston qualifying
This change targets courses like the Revel series and other downhill marathons that have become popular among BQ chasers. BAA data showed that runners who qualified on steep downhill courses ran significantly slower at Boston than their qualifying times suggested.
It is already biting. The BAA reported that 240 accepted qualifying times for 2027 came from events carrying a net-downhill index.
If you are planning to qualify on a downhill course, add the penalty before you compare yourself to the cutoff. A 2:58 on a steep net-downhill course is scored as a 3:03, and that is the number the BAA ranks you by.
How to Calculate Your Real Chances
Instead of guessing, use data to understand where you stand.
Step 1: Know your predicted marathon time
Use a recent race result (5K, 10K, or half marathon) to estimate your marathon potential. VDOT-based calculators give you science-backed predictions based on Jack Daniels' running formula.
Step 2: Compare to your BQ standard
Calculate how far under your qualifying standard your predicted time falls. This is your "buffer."
Step 3: Compare your buffer to historical cutoffs
Look at the table above. If your buffer exceeds the cutoffs from recent years, your chances are strong. If you're right at the cutoff line, it's a coin flip.
Step 4: Set a realistic target
Based on historical acceptance patterns, aim for at least 7 minutes under your BQ standard for high confidence. Seven minutes would have cleared every year since 2021. Five would have missed three of the last four.
The Bottom Line
Meeting the Boston Qualifying standard is a significant achievement. But if Boston is your goal, understand that qualifying is step one. The real target is beating your standard by enough margin to survive the cutoff.
Based on recent trends, five minutes under is no longer enough. The last four cutoffs were 5:29, 6:51, 4:34 and 5:17, so aim for seven minutes under for high confidence and 10 if you want to stop thinking about it.
The lottery softens a near miss, but it is a one in nine chance on a draw the BAA has not promised to repeat. Treat it as luck, not as a target.
The sport of marathoning continues to grow, and runners continue to get faster. Plan accordingly.
Once you have your target time, execution matters. A strong race pacing strategy can be the difference between a BQ and a near-miss.
