Spring vs Fall Qualifier: When to Run Your BQ
Both spring and fall marathons can qualify you, but the timing changes your margin for error.
Fall qualifier
A fall marathon often falls close to the September registration for the next April Boston, which means a fast fall race can count almost immediately. The risk is that if you miss, there is little time for another attempt before registration closes.
Spring qualifier
A spring marathon gives you the rest of the year to improve or take a second shot before the next registration, and it still falls inside the window. The trade-off is a longer wait between your time and the race you are entering.
The rule that matters
Qualify as early in the window as you can. Early times give you a fallback race if your buffer turns out to be too thin for the predicted cutoff. Check whether your buffer is safe with the predictor.
Frequently asked questions
Is a fall or spring marathon better for a BQ?
Either works. Qualify early in the window so you have time for a second attempt if your first buffer is too small.
Does a fall marathon count for the next Boston?
Usually yes, if it falls inside the qualifying window. Confirm the exact window dates each year.
