What does it take to qualify for Boston?

Qualifying for Boston means meeting an age- and division-based marathon standard on an eligible course. Acceptance depends on the edition’s entry rules and available places. Start with the current standard, then build a realistic training target from recent race evidence. The published 2027 cutoff was 5:17 faster than the standard.

How much faster should I run than my standard?

For 2027, 5:17 was the published cutoff reference. It is historical selection information, not a prediction for the next edition. Plan a margin you can support with training evidence; don’t turn an unknown future cutoff into a guarantee.

What changed for downhill courses?

From 2027, the B.A.A. adds time to qualifying results from courses with substantial certified net descent. Check the official course index before choosing a qualifying race. The calculator shows the published thresholds and the effect on your result.

Where should I start the training block?

Use a recent race or representative training session to assess current fitness. Goal pace is useful for planning, but hard sessions should match what you can currently do.

How do I know the goal fits my week?

Review the longest session, consistent weekly availability and recovery demands. I would rather revise a date than build a plan that only works on paper.
