The BQ Cutoff: You Need to Run FASTER
Important: Hitting the Standard May Not Be Enough
Due to high demand, the Boston Marathon typically requires you to run 5-10 minutes faster than the official qualifying time. In recent years, the cutoff has been:
- 2023: 5 minutes 29 seconds under BQ time
- 2022: 7 minutes 47 seconds under BQ time
- 2021: 7 minutes 47 seconds under BQ time
Bottom line: Aim for at least 5 minutes under your BQ standard to be safe.

Key Workouts for BQ Training
1. Marathon Pace Long Runs
Run 16-20 miles with the final 8-10 at BQ goal pace. This is the most specific workout for marathon success.
2. Tempo Runs at Threshold
8-10 miles at 15-20 seconds faster than marathon pace. Builds the lactate threshold critical for sustained pace.
3. Yasso 800s
Run 8-10 x 800m at your goal marathon time in minutes:seconds. For a 3:20 marathon, run each 800m in 3:20.
4. Long Intervals
4-6 x 2 miles at 10-15 seconds faster than marathon pace with 3-minute rest. Builds speed endurance.
Choosing the Right BQ Marathon
Not all marathons are created equal for BQ attempts. Look for:
Best BQ Course Characteristics
- Flat or Net Downhill: CIM, Grandma's, Sugarloaf, Revel races
- Cool Weather: October-April races in temperate climates
- Fast Certified Course: Look for USATF certification
- Good Pacing Support: Pacers for your goal time
Top BQ Marathons
- California International Marathon (CIM) - Sacramento, December
- Grandma's Marathon - Duluth, June
- Chicago Marathon - Chicago, October
- Berlin Marathon - Berlin, September
- Revel Mt. Charleston - Las Vegas, November (downhill)
Race Day Strategy for Your BQ Attempt
First Half: Conservative Banking
Run 30-60 seconds slower than goal pace for miles 1-3, then settle into pace. You need energy reserves for miles 20-26.
Middle Miles (13-20): Lock In
This is where you execute. Stay exactly on pace, no faster. Resist the urge to push when feeling good.
The Final Push (20-26.2): Empty the Tank
If you paced correctly, you should be able to maintain or slightly speed up. If you're dying, you went out too fast.
Use Your Cushion Wisely
If targeting 5 minutes under BQ, you have 11 seconds per mile of cushion. Use it in the final 10K if needed.
Frequently Asked Questions
How hard is it to qualify for Boston?
Very hard. Only about 2-5% of marathon finishers run fast enough to qualify. It requires months of dedicated training and multiple marathon attempts for most runners.
Can I use a downhill marathon to qualify?
Yes! Any USATF-certified marathon course is acceptable, including point-to-point downhill courses like Revel races.
What happens if I just miss my BQ time?
You'll need to try again. There's no partial credit or appeals process. But you've proven you're close—adjust training and try again within 6 months.
Do I need to run negative splits to BQ?
No, but even pacing or slight negative splits give you the best chance. Positive splits (slowing down) often lead to blowing up and missing the standard.
How many marathons does it take to get a BQ?
Most runners take 2-5 marathon attempts. Your first marathon teaches you the distance. By marathon 3-4, you know how to pace and fuel properly.
