Should You Run a Second Qualifier?
If your first qualifier cleared the standard but only by a little, a second race inside the window can turn a coin-flip application into a safe one.
When it is worth it
Compare your buffer to the predicted cutoff. If you are below or near 5:15 under the standard, your application is a gamble, and a second marathon to add margin is often worth the effort. If you already have 7:00 or more, a second race adds little but risk and fatigue.
How to plan it
Leave enough recovery between marathons, pick a flat course, and target the standard minus a comfortable buffer. The BAA keeps your fastest qualifying time, so a second race can only help your case. Use the predictor to decide whether the gamble of your current buffer is worth a second start line.
Frequently asked questions
Does Boston use my fastest qualifying time?
Yes. If you run more than one qualifier in the window, your fastest eligible time is what counts.
Is a thin BQ worth re-racing?
If your buffer is at or below the predicted cutoff, a second race to add margin is often worth it. A large buffer rarely needs re-racing.
