Concept
Marathon readiness
The capacity to absorb consistent training, progressively longer running, and the recovery demands of preparing for a half marathon or marathon.
What readiness looks like
Readiness is shown by repeatable ordinary weeks, stable easy volume, and reliable recovery rather than one unusually long run.
Why the distance matters
A marathon creates substantially greater durability, fueling, and recovery demands than a half marathon.
Why life capacity matters
Available time, sleep, food, stress, and recovery support determine whether a training block is realistic.
How to use it
Review several months of consistency and choose a distance that does not require a sudden jump in long-run or weekly load.
Common misconception
Completing one long run does not prove that the body can absorb a full marathon training block.
