Decide whether this 14-week half-marathon plan fits
Fourteen weeks gives enough runway to build durable frequency before the most specific half-marathon work. Use the extra time to separate progressions and learn recovery, not to schedule fourteen identical weeks.
Use current evidence, not the finish time you hope to run. Compare the opening week with the last four repeatable weeks: running frequency, longest recent run, faster work, strength, symptoms, sleep opportunity, and next-day function. A returning runner can use the first phase to stabilise easy volume, but the first week must still fit current capacity.
| Readiness signal | Accept the opening week when | Add foundation or step down when |
|---|---|---|
| Frequency | the first-week run count is familiar | the plan adds a day you have not sustained |
| Long run | recent duration and recovery are comparable | the first long run already feels like a test |
| Faster work | one controlled session is absorbed well | every faster session becomes maximal |
| Strength | technique remains sound without lasting soreness | lifting removes the next key run |
| Life load | the week fits work, care, travel, and sleep | completion depends on perfect circumstances |
This page is an educational framework, not an automatic prescription. A calculator pace, old personal best, or single strong workout does not certify readiness.
Protect the main tradeoff
The fourteen-week tradeoff is foundation versus goal-pace impatience. Early controlled work should support the later race block rather than prove a finish time.
Give every session one job. Easy running develops repeatable volume; controlled quality work develops the chosen race demand; strength supports force and tissue capacity; recovery makes the next useful session possible. Avoid turning every run into medium-hard work.
Give the runway four phases
Use four foundation weeks, four development weeks, four specificity weeks with a reduced confirmation week, and two taper weeks adjusted to completed training.
- Foundation: stabilise frequency, easy duration, strength technique, and normal recovery.
- Development: progress one important variable while the rest of the week remains repeatable.
- Specificity: rehearse the demands that distinguish this event and duration.
- Taper: reduce fatigue while keeping familiar movement and a small amount of rhythm.
Taper research supports lower volume while retaining familiar intensity and frequency, but it does not prescribe one universal final week. Keep the principle and adjust from completed work.
Use a weekly evidence card
Record duration, surface, terrain, perceived effort, symptoms, sleep opportunity, strength load, and next-day function. Then choose progress, hold, reduce, or replace:
- Progress when the key work was controlled and ordinary function returned.
- Hold when the work was completed but effort or recovery cost rose.
- Reduce after illness, abnormal fatigue, or pain that changes movement.
- Replace when weather, surface, travel, or schedule makes the original job unsafe.
Concurrent-training evidence supports building endurance and strength together, while sequence and fatigue still affect the cost. Remove optional load before removing the one session that best answers the current training question.
Work through one real decision
If consistency improves through week four but work travel removes one midweek run, keep the long run and one quality session, move strength away from the quality day, and hold total volume.
Write the decision before the next week begins. “Do more” is not a usable adjustment. Name the session you will retain, the variable you will reduce, and the evidence that allows normal progression to resume.
Handle a missed or disrupted week
A disruption in the foundation phase can be met by extending it. A disruption in specificity should reduce the peak rather than push hard work closer to race day.
Do not stack missed long running, faster work, and heavy strength into the next seven days. Resume from current capacity, protect the next essential session, and rebuild the sequence. A calendar cannot absorb load on your behalf.
Rehearse the distinct race job
Use a course-aware rehearsal that pairs pace band, fueling, and the planned first 5K. Finish with control; the objective is information, not exhaustion.
Use a bounded rehearsal and stop before it becomes a race. Record what the session taught you about pacing, equipment, fueling, terrain, and recovery. Pacing research describes population patterns; your completed sessions still own the individual decision.

Safety boundary
Stop and seek qualified care for chest pain, fainting, confusion, severe breathing difficulty, or pain that changes normal movement. Seek professional guidance for persistent symptoms, recovery that is not returning, or uncertainty after illness or injury.
