Is thirteen miles really just a longer 5K, or does the training actually need to change? How do you build the weekly mileage without getting hurt three weeks before race day? The Half Marathon Training Plan builds that progression around your own timeline instead of a one size plan.
Short answer: The Half Marathon Training Plan is a free AI tool that builds a structured running schedule toward a half marathon, covering weekly mileage, long runs and rest days, sized to your timeframe and current fitness.
What is Half Marathon Training Plan?
The Half Marathon Training Plan is a free AI writing tool for runners with a half marathon goal, whether it is a first attempt at the distance or a push for a faster time. Describe your current weekly mileage, how many weeks until race day, and any scheduling constraints, and it drafts a week by week plan built around your actual starting point. It works for a runner coming from a 5K base as well as one returning to longer distances after time off.
How Does Half Marathon Training Plan Work?
Type your current mileage, goal and available training days into the prompt box, then pick an engine from the model selector. Tune the advanced options and generate. The plan lands in the output card, tagged with a word count and reading time, and it copies, shares, plays back through the listen button, or exports as TXT, Word or HTML. Older plans stay reachable through the activity history panel, useful when training gets adjusted after an injury scare.
Who Should Use It?
A first time half marathon runner fits here most obviously, but it works just as well for someone who already finished the distance and wants a push toward a faster time. A runner coming back after months off benefits from starting lower than a generic chart assumes, which is where an honest starting point earns its keep. It also suits a demanding shift pattern, since Include Buffer Time and the flexibility slider exist for exactly that.
Choosing The Right Settings
| Option | What it controls | Suggested starting point |
|---|---|---|
| Timeframe | Day, Week, Month, Quarter or Custom scope | Quarter, a common build-up window for a half marathon |
| Detail Level | Overview, Standard, Detailed or Very Detailed | Detailed, longer distance training benefits from clearer weekly guidance |
| Priority Focus | Balance, Goals, Deadlines, Well-being and more | Balance, most runners need consistency more than an aggressive push |
| Format | Timeline, Calendar, Table, Bullet List and more | Calendar, easiest to see mileage build across the full training block |
What works well
- Builds mileage progressively instead of long weekend runs from the start
- Include Milestones flags key long runs and taper points in the plan
- Include Buffer Time keeps a missed week from derailing the build-up
What to watch for
- An unrealistic starting mileage ramps up too fast, be honest about your base
- The tool cannot replace a coach or doctor for anyone with a prior injury
- Taper weeks matter as much as build weeks, do not skip them
Tips And Common Mistakes
- Increase weekly mileage gradually, a sudden jump is the most common cause of injury
- Turn on Include Notes for pacing guidance on long runs, not just the mileage
- Respect the taper in the final two weeks, it protects the fitness already built
Note This tool builds a training schedule, not medical advice. Check with a doctor before starting a new distance running programme.
Example Inputs And Outputs
Picture a runner with a first half marathon twelve weeks out, running three days a week for about 15 miles total. Timeframe set to Quarter, Detail Level to Detailed, Format to Calendar, plus Include Alternatives for a backup session, covers that case well. What comes back reads something like: "Week 1: 3 runs, 12 miles, easy pace, rest Tuesday and Friday…" building toward a longer run before the taper. Push flexibility higher if the week genuinely varies rather than following a fixed pattern.
This planner does not require signing up on EizTools, and the AI engine behind your plan is whichever one you choose from the dropdown, not a fixed default. Runners starting from a shorter distance should begin with the 5K Training Plan and build toward this one once that base is solid.
Frequently Asked Questions
How much running experience do I need for the Half Marathon Training Plan?
Describe your current weekly mileage honestly, ideally already comfortable running a 5K, and the plan will build from that base.
Does it include a taper before race day?
Yes, mention your race date and the plan will typically reduce mileage in the final weeks to protect your fitness for race day.
Can I get a plan built around a specific target time?
Yes, mention your goal time and set Priority Focus to Goals for a plan that leans toward pace-focused sessions.
Is the Half Marathon Training Plan free to use?
Yes, there is no account to set up and no fee anywhere in the process. Regenerate the plan whenever your mileage or race date changes.
What happens if I miss a week of training?
Turn on Include Buffer Time so the plan builds in room to adjust rather than assuming every session runs on schedule.
A half marathon goal becomes achievable once mileage builds gradually instead of all at once. Describe your current base and race date, choose a pace that fits, and let the Half Marathon Training Plan carry you to the start line ready.
