Choose the schedule your current week can absorb

A half-marathon plan PDF should organize repeatable running, not force an ideal calendar onto a real one. Start by listing the days you can train consistently, the longest recent run that left normal next-day function, current health and pain, and the date of the goal race. A longer plan is often the better choice when the first week already looks like a stretch.

Give every run a job

SessionPrimary jobGuardrail
Easy runaerobic frequency and recoveryconversational effort
Quality sessioncontrolled threshold or race-specific workone clear target, not a time trial
Long rundurability and fueling practicefinish without destroying the next week
Strengthsupport force and tissue capacitydo not crowd the hardest run
Rest or recoveryabsorb the workdo not repay missed volume

The spreadsheet becomes useful when actual work is recorded beside planned work. Add duration, effort, symptoms, sleep opportunity, and what changed. If the same weekday repeatedly fails, move the plan around the constraint rather than treating every miss as a motivation problem.

Use checkpoints instead of calendar obedience

Every two to three weeks, ask whether easy running remains easy, the long run is progressing without a prolonged recovery cost, and the quality session is repeatable. Hold or reduce load when illness, pain, or abnormal fatigue changes ordinary function. Do not advance distance and intensity together merely because a new row begins.

Connect the file to the half-marathon training hub, the race-morning breakfast practice, and the first-5K pacing plan.

Use the running pace calculator only after the weekly structure is stable; calculator pace does not replace the effort and recovery checks above.

Safety boundary

Stop for chest pain, fainting, severe breathing difficulty, or pain that changes normal movement. This downloadable plan is educational and not medical advice or an individualized readiness assessment.

Assumptions

What this tool assumes

  • This is a week-by-week plan summary (not a day-by-day calendar).
  • If you provide a race date, we calculate a recommended start date for planning.

Limitations

When this estimate may be less reliable

  • Does not adjust for injury history, medical conditions, or major life constraints.
  • If you’re new or returning, use run/walk on easy runs to protect durability.

FAQs

How many days per week should I use the half-marathon PDF?

Choose the frequency you can already tolerate and recover from. More listed days are not better when they make the key work inconsistent.

What if the first week is too hard?

Select a longer or lower-volume variation, or build a base first. Do not treat a difficult first week as a test you must pass.

Should I make up a missed long run?

Usually not by stacking it beside the next key session. Resume from current capacity and protect the continuity of the following week.

When should I practise race breakfast?

Use suitable long runs and race-timing rehearsals well before race week, with familiar foods and enough time to change one variable if needed.
