A half marathon asks for consistent endurance, not a perfect calendar. Use this 14-week example to understand the progression, then let Easy Goal Coach create a personalised half marathon plan around your fitness, race date, available days, fixed activities and real life.

Who this plan suits
Ready to turn regular running into 21.1 kilometres.
This framework suits runners preparing for a first half marathon and more experienced runners who want a controlled, realistic build. Before starting, you should ideally be able to run or run-walk for about 30–40 minutes and have trained consistently two or three times a week for several weeks.
If you are starting from no running, recovering from a long break, or cannot yet manage 30 minutes of comfortable run-walk activity, begin with our running plan for beginners. Building that foundation first is more useful than rushing into longer runs.
Example 14-week progression
Build the long run while the whole week grows sensibly.
This example sits in the middle of a typical 12–16-week range. A 12 week half marathon training plan may combine some early phases; a 16-week plan can spend longer establishing the base. Distances are ranges, not weekly targets every runner must hit.
WeeksExample long runExample weekly volume and focus
Three, four or five running days can all work.
Keep every run purposeful
A half marathon training plan 3 days a week can use one easy run, one controlled quality or steady run, and one long run. Leave recovery between the harder or longer days.
Add easy frequency
Use the same three anchors and add a short easy run. This often spreads the weekly volume more comfortably than making the key sessions much longer.
Earn the extra day
Add another easy or recovery run only when your training history supports it. Five days should distribute useful volume—not create five demanding sessions.
Fit the plan to real life
The best pattern is the one that respects work, family, sleep, fixed training and recovery. Consistency matters more than copying somebody else’s weekdays.
Strength and cross-training
Support the running—not compete with it.
A half marathon training plan with strength training may include one or two short sessions each week. Prioritise controlled lower-body, calf, hip and trunk work, and avoid placing an unfamiliar heavy session immediately before the long run or key running workout.
Cycling, swimming or other low-impact aerobic work can support fitness when it fits your total capacity. Existing classes and fixed activities still create fatigue, so Easy Goal Coach counts them as part of the week instead of treating them as free extras.

Your plan should respond when life changes.
Easy Goal Coach begins with your current fitness, half marathon date, available training days, daily time limits, preferred long-run day, fixed activities, optional cross-training and anything important your coaches should know. That creates a plan your actual week can hold.
As you train, completed workouts, missed sessions and honest feedback are reviewed. Future training can change when there is a genuine reason—such as disrupted consistency, a changed schedule or a different training response—and stays stable when the current plan is still appropriate.
Protect the work you have already done.
Keep easy days easy
Harder training only works when you can absorb it. Sleep, food, rest and genuinely easy running belong inside the plan.
Do not repay the calendar
Skip the missed session and continue sensibly. Do not stack runs together or turn an easy day hard simply to recover a tick box.
Resume below your limit
After several missed days, repeat or reduce rather than jumping straight to the latest scheduled volume. Illness or injury may require more caution.
Reduce fatigue, keep rhythm
The final one to two weeks usually reduce volume while retaining small amounts of familiar running. Avoid late fitness tests and unfamiliar hard work.
Before you start the build.
How long should a half marathon training plan be?
Twelve to sixteen weeks works for many runners who already have a basic running habit. A newer runner may need longer, while an experienced runner may begin from a stronger base. The calendar should match your starting fitness rather than force a standard duration.
Can I train for a half marathon three days a week?
Yes. Many runners can prepare with three well-spaced runs: an easy run, a purposeful steady or quality session, and a gradually progressing long run. The appropriate volume still depends on your background and recovery.
Do I have to run 21.1 km before race day?
No. Many plans peak below the full race distance. The right longest run depends on weekly volume, experience, pace, time on feet and recovery. More is not automatically better.
How fast should the long run be?
Most long runs should feel easy and controlled enough for conversation. Some experienced runners may include purposeful sections later in the plan, but turning every long run into a race makes recovery harder.
What should I do if I miss a long run?
Do not squeeze it into the next day if that creates a difficult sequence. Continue from a sensible point, considering why it was missed and how much training was interrupted. Easy Goal Coach can review what comes next instead of blindly shifting every workout.
Can I keep strength training?
Usually, yes, if it fits your total workload and experience. Keep the work controlled, allow recovery around important runs, and reduce or adjust it when fatigue begins to interfere with running quality or recovery.
When should I seek medical advice?
Speak with an appropriate healthcare professional if you have concerns about starting exercise, a health condition affected by training, or pain and symptoms that alter normal movement or persist. This page offers general training information and is not medical advice.
