Beginner half marathon plan

A half marathon training plan for beginners built around your real week

This page is for runners who want structure for a half marathon build without committing to marathon loads. You get a clear sample schedule and what the plan should cover, then step into the YourRunGuide planner with a half marathon preset already loaded.

Best fit if you can already run about 5 to 8 km comfortably and want a first half marathon finish, or a steadier build for a better next one.

Start my half marathon plan

At a glance

  • Goal shape: Long-run progression plus half-marathon specific work
  • Typical weekly rhythm: 3 to 4 run days for most beginners
  • Best for: First half marathon or a sharper half marathon
  • Planner preset: Race plan with half marathon distance selected
  • What changes: Mileage, long run progression, target pace, recovery constraints
  • What matters most: Long-run durability, steady mid-week mileage, race-pace exposure

Who this page is for

  • You already run a few times per week and want a structured half marathon build instead of guessing the long-run jumps.
  • You want help balancing long runs, recovery, and a little race-pace work without marathon-level volume.
  • You want a plan that respects busy weeks, walk-run options, and niggles — not a template built for perfect consistency.

What the planner should adapt for a half marathon build

  • Current weekly mileage, because half marathon plans break when the starting volume is wrong.
  • Target finish or just-finish intent, which changes long-run emphasis and race-pace dose.
  • Available days for long runs and optional workouts.
  • Walk-run preferences, injury history, or load sensitivity, so progression stays honest rather than optimistic.

What a half marathon build usually needs to cover

Base phase

Anchor the weekly shape

Before the biggest long runs, the plan needs a stable rhythm of easy running, a comfortable long run, and optional strength.

Build phase

Extend the long run and add race-pace work

The middle block grows long-run durability and introduces short half marathon pace segments, without tipping into marathon-style loading.

Peak and taper

Sharpen without losing fitness

The final stretch reduces fatigue, reinforces goal pacing, and arrives at the start line healthy.

Common half marathon mistakes this page should help avoid

  • Starting the build with optimistic long runs that do not match recent training.
  • Running every long run hard instead of treating them as aerobic work with some goal-pace exposure.
  • Skipping easy days because the schedule looks too simple, then struggling in the final build weeks.
  • Going out too fast on race day and paying for it from kilometre 16 onward.

Half marathon training plan for beginners FAQs

Is this half marathon training plan for beginners?

Yes. The preset defaults to a just-finish intent and respects your current mileage rather than assuming you already run high weekly volume. You should already be comfortable with short continuous runs or a walk-run habit.

How many weeks does a good half marathon build need?

Ten to sixteen weeks is typical. The sample above is a 12-week shape. The planner adapts around your race date and current load.

Can I use walk-run intervals in a half marathon plan?

Yes. Planned walk breaks on long runs and even on race day are a valid strategy, especially for a first finish. Tell the planner your preference, or set intervals with the walk-run calculator.

What if I am returning from injury?

Start only when easy running or walk-run work is pain-free and a clinician has cleared you if needed. Keep progression conservative, prioritize flat easy runs, and rebuild duration before race-pace work. The planner can respect recovery constraints; do not force the sample schedule if your body is still settling.

Do I need a recent benchmark time?

No. A recent 5K, 10K, or long run gives more precision, but the planner can still build conservatively from uncertainty. Pair it with the race predictor once you have a recent result.

How is this different from a PDF half marathon plan?

This page gives context and a sample structure. The planner builds the actual week-by-week schedule around your availability, fitness, and constraints.
