If the Boston Marathon is on your bucket list then you've come to the right place.
This guide covers everything you need to know about the Boston Marathon qualification process, what the standards actually mean, how the registration system works (and why your qualifying time needs to be faster than you think), and what a 6-month build toward a BQ might look like.

First Off: Why Does Boston Require Qualification?
The Boston Marathon has been held annually since 1897, making it the world's oldest annual marathon. It is organised by the Boston Athletic Association (BAA) and takes place every year on Patriots' Day, the third Monday in April.
Unlike most major marathons, Boston does not use a lottery system for the majority of its field. To enter as a general participant, you need to have run a qualifying time at a certified marathon within the registration window. That time is assessed against your age and gender at the time of the Boston Marathon itself (not at the time of your qualifying race), and it needs to meet the BAA's published standard for your age group.
The race is consistently oversubscribed. More runners qualify than the field can hold, which means simply hitting the standard is often not enough.
Oh...Running The Qualifying Time Means Nothing
The Boston Marathon field is capped. In recent years, significantly more athletes have qualified than the field can accommodate. The BAA handles this by accepting qualifiers in order of how much they beat their standard by, starting with the fastest runners relative to their standard and working down until the field is full.
In 2024, athletes needed to beat their qualifying standard by 5 minutes and 29 seconds to be accepted. It used to only be about 2 minutes - so this increase is quite substantial. So unfortunately, hitting the time exactly is likely going to leave you minutes off the needed time to actually hit the tarmac of Boston.
So, now we've determined how to qualify for Boston, we now need to get you registered. Here's exactly how you're going to do it.

Step-By-Step: How the Registration Process Works
Step 1: Run a qualifying time at a certified marathon
Your qualifying race must be a World Athletics certified marathon course. (Most major marathons qualify). The time must be run within the registration window set by the BAA (typically the previous September through the current September for the following April race). Check baa.org for the exact window each year.
For Canadian runners, the best qualifying races are the Scotiabank Toronto Waterfront Marathon in October and the BMO Vancouver Marathon in May. Both are certified courses with strong fields and conditions suited to fast times.
Step 2: Verify your time is officially recorded
Your time needs to be chip-timed and officially recorded on the race results page. Screenshots of your watch do not count. Make sure you receive your official result before the registration window opens.
Step 3: Register during the rolling registration window
The BAA opens registration in three waves.
| Registration Wave | Who Can Register |
|---|---|
| Wave 1 (typically mid-September) | Athletes who beat their standard by 20 or more minutes |
| Wave 2 (2 to 3 days later) | Athletes who beat their standard by 10 or more minutes |
| Wave 3 (2 to 3 days later) | Athletes who beat their standard by 5 or more minutes |
| General registration (2 to 3 days later) | All remaining qualifiers |
Each wave closes when the field fills. If you are registering in the general wave, do it on the first day it opens for the best shot of making it.
Step 4: Wait for acceptance confirmation
After the general registration window closes, the BAA reviews all submissions and accepts athletes in order of how much they beat their standard by, until the field is full. Athletes who are not accepted are notified and may be offered a spot on the waitlist.
Step 5: Book travel and accommodation early
Boston in April is in high demand. Hotels near the course fill within days of registration opening. If you are travelling from Canada, book as soon as you receive acceptance confirmation. Take it from me: Do not wait. And now, the fun part:

What Does a 6-Month BQ Build Actually Look Like?
Six months is enough time to make a meaningful improvement in your marathon time if your current fitness is within range of your standard and your training is structured correctly. Here is what I would build for an athlete targeting a BQ at Toronto Waterfront in October, starting in April.
Phase 1: Base (Weeks 1 to 6)
The foundation. No intensity, no pace work, no racing. The goal in this phase is to build your weekly volume to the point where the quality sessions in Phase 2 can actually land. Most runners want to skip this. But fun fact: most runners who skip it get injured in week 10.
| Week | Focus | Long Run |
|---|---|---|
| 1 to 2 | Easy running only, 5 to 6 days | 18 to 22km |
| 3 to 4 | Easy running, introduce strides | 22 to 26km |
| 5 to 6 | Easy running, strength work twice weekly | 26 to 28km |
Phase 2: Build (Weeks 7 to 16)
This is where the work happens. Two quality sessions per week (one threshold, one long run with race pace segments), with easy running filling the rest of the week. I find this phase manageable but constantly stretching you - which makes it fun and fast!
| Week | Quality Session 1 | Quality Session 2 | Long Run |
|---|---|---|---|
| 7 to 9 | 4 x 8 min at threshold | Easy with strides | 28 to 30km easy |
| 10 to 12 | 5 x 8 min at threshold | 25km with 10km at race pace | 30 to 32km |
| 13 to 14 | 3 x 10 min at threshold | 28km with 14km at race pace | 32km |
| 15 | Cutback week | Easy sessions only | 24km easy |
| 16 | Race simulation | 20km with 10km at race pace | 28km |
Phase 3: Peak and Taper (Weeks 17 to 24)
The final 8 weeks before race day. Volume peaks around week 19 to 20, then drops progressively through the taper. Most athletes feel terrible in weeks 21 to 22 (the taper dip is real and physiological, not just psychological). Trust the process.
| Week | Focus | Long Run |
|---|---|---|
| 17 to 18 | Highest volume, two quality sessions | 34 to 35km |
| 19 to 20 | Peak week, race simulation workout | 35km with race pace segments |
| 21 to 22 | Volume drops 20%, intensity maintained | 28km |
| 23 | Volume drops 40% from peak | 22km easy |
| 24 (race week) | Easy running, race day preparation | Race day: 42.2km |
