Best Half Marathon Training App For 13.1 Miles
Most runners who fail a half marathon training block do not fail because they chose the wrong plan. They fail because they stop showing up around week 6 when mileage peaks, novelty wears off, and life gets in the way. This ranking puts the app with the highest chance of getting you to the start line at number one, then ranks the best structured plans honestly by what they actually do best.
Who this guide is for
This guide is for runners who have signed up for a half marathon, or are seriously thinking about it, and want to know which app to open on Monday morning. Weeks 1 through 4 of a training block feel manageable. Around week 6, the long runs get long, the weather turns, and motivation runs out. The setup that actually works is a structured plan for the what and a motivation layer for the why. If you have a plan but keep skipping runs when work gets busy or the weather is bad, Motera pairs with any plan on this list and adds the missing layer that keeps a training block alive through the long slog before taper. Every app here was tested on iPhone.
The 8 Half Marathon Apps, Ranked
Motera
Best for actually finishingEditor's pickTerritory capture and local leaderboards turn every training run into a move you cannot afford to skip, so you show up in week 6 when motivation is lowest and the block is most likely to fall apart.
Ranked first for adherence, not plan quality. Motera is not a training plan app. It pairs with any plan on this list, including Runna, Nike Run Club, and Hal Higdon, and gives every training run a reason to happen that goes beyond pace targets and mileage logs. Most runners who abandon a 13.1 block quit in weeks 5 through 7, not week 12. Motera targets that specific window.
Runna
Best adaptive planDynamic pace targets that adjust to your fitness every week so the plan bends around your life instead of breaking.
Nike Run Club
Best free pickCoach Bennett talks you through every run with zero ads, and the full 12-week guided plan costs nothing.
Garmin Coach
Best for Garmin ownersFree structured plan pushed directly to your Garmin watch, no manual session entry needed.
Hal Higdon
Best plan libraryThe gold standard plans used by hundreds of thousands of runners, available as free PDFs or inside a clean app.
Adidas Running
Best for beginnersGentle ramp with walk breaks baked into early weeks so new runners build mileage without burning out.
Strava Summit
Best for communitySocial pressure from your training feed is a real motivator, and segment competition sharpens your long run effort.
Runkeeper
Best for simple trackingClean interface, solid audio cues, and a no-fluff 12-week goal plan for runners who want structure without complexity.
The 12 Week Plan Inside These Apps
Every mainstream half marathon plan looks roughly like this. If your app is missing cutback weeks or peaks over 12 miles, switch apps.
| Week | Long Run | Total Mileage | Focus |
|---|---|---|---|
| 1 | 4 mi | 12 mi | Base week, two easy, one tempo |
| 2 | 5 mi | 14 mi | Add first hill repeats |
| 3 | 6 mi | 16 mi | Introduce race pace segments |
| 4 | 5 mi | 13 mi | Cutback week, recover |
| 5 | 7 mi | 18 mi | Long run past 10K |
| 6 | 8 mi | 20 mi | Tempo extends to 3 miles |
| 7 | 9 mi | 22 mi | Peak mid block intensity |
| 8 | 7 mi | 17 mi | Cutback, sharpen |
| 9 | 10 mi | 24 mi | Double digit long run |
| 10 | 11 mi | 26 mi | Peak mileage week |
| 11 | 12 mi | 24 mi | Final long before taper |
| 12 | 6 mi + race | 18 mi | Taper and race day |
How To Pick The Right App For You
Plan duration
Longer is not always better. Beginners need 16 weeks, experienced runners can sharpen in 10.
Adaptivity
Static PDF plans ignore a rough week. Runna and Garmin Coach actually shift the plan when you miss a session.
Session variety
Look for tempo, intervals, long runs, and easy days. Any plan that is only long runs will stall.
Recovery logic
Good apps build in cutback weeks every 3 to 4 weeks. Skip the app that just stacks mileage.
You Picked The Plan. Now Install The App That Gets You To The Start Line.
Open Runna, Nike Run Club, Hal Higdon, or whatever plan you picked above on your next run. Then open Motera. Both apps track the same session. Motera turns it into territory you own on a live map, a leaderboard you climb against local runners, and a city that opens up block by block over 12 weeks. The plan tells you what to run. Motera makes you want to. Free on iOS. 30 seconds to install. No plan to follow inside the app, so nothing to learn and nothing to switch.
MoteraWhat a typical week looks like

- Tuesday: Intervals. 6 x 400m at 5K pace with 2 min jog recovery.
- Wednesday: Easy 3 to 4 miles at conversational pace.
- Thursday: Tempo. 20 minutes at half marathon pace sandwiched between warm up and cool down.
- Friday: Rest or 30 minute shakeout jog.
- Saturday: Long run. Slow. One minute per mile slower than goal race pace.
- Sunday: Easy recovery run or full rest, your choice.
Frequently Asked Questions
What is the best half marathon training app?
Runna is the most popular paid pick because it adapts plans to your pace, fitness, and race date. Nike Run Club is the best free option with a proper guided 12 week plan. Garmin Coach works if you already own a Garmin watch. Motera layers game mechanics on top of any plan so you actually stick to it.
How many weeks do I need to train for a half marathon?
Most apps default to 12 weeks for runners who can already run 3 to 4 miles. Absolute beginners should pick a 16 week plan that bakes in a 5K base. Experienced runners targeting a sub 1 hour 45 can run a sharper 10 week cycle.
Are half marathon training apps worth it?
Yes if you struggle with consistency or pacing. The value is not the plan itself, it is the structure that tells you exactly what to run today, adjusts when you skip a session, and keeps you from doing every run too fast.
Can I train for a half marathon for free?
Yes. Nike Run Club offers a full 12 week guided audio plan at no cost. Adidas Running has a free structured plan. Hal Higdon publishes free PDFs you can load into any run tracker. Pair a free plan with Motera for accountability and capture based motivation.
How long should my longest run be before a half marathon?
Most plans peak at 10 to 12 miles two to three weeks before race day, then taper. You do not need to run the full 13.1 miles in training. Race day adrenaline and tapered legs cover the last mile or so.
Which app has the best audio coaching?
Nike Run Club has the richest catalog with Coach Bennett and guest runners. Runna has structured audio cues that call out pace targets during intervals. Runkeeper has a lighter audio cue system for splits and pace.
Do I need a GPS watch or is a phone enough?
Phone is enough. A watch adds convenience and heart rate data, but every major half marathon training app runs fully on iPhone. Many runners train with the phone in an armband and only use a watch on race day.
What if I miss a week of training?
Most adaptive apps will shift you back one week or compress the next block. The wrong move is to cram two weeks of mileage into one. Runna, Garmin Coach, and Nike Run Club all handle missed weeks gracefully.
Can a beginner use these apps?
Yes. Runna, Nike Run Club, and Adidas Running all have beginner specific half marathon plans that assume you are starting from a 5K base. Pair these with a run walk approach in the first four weeks if needed.
How do I stay motivated during a 12 week block?
Stack a training plan with a motivation layer. Motera turns every training run into territory you capture and hold, so even a recovery jog feels like progress. Plans tell you what to run, Motera tells your brain why today matters.
Why Half Marathon Trainees Download Motera
A good plan is table stakes. The question is whether you will execute it for 12 straight weeks when life pushes back. Here is what changes when you add Motera to your training block.
Week 6 survival: Research on 12-week training blocks consistently shows the largest dropout cluster between weeks 5 and 7. Motera gives every run a tangible outcome beyond pace data. Territory you captured on Tuesday belongs to you. Skip Thursday and a competitor takes it. That single mechanic pulls more runners out the door than any coaching cue or push notification.
Long runs become something more: Your 10-mile Saturday long run does not just add a line to a training log. It opens new streets on the Fog of War map, locks in territory across an entire neighborhood, and leaves a permanent visual record on your city. Over a 12-week block you watch your city open up section by section, and that cumulative picture makes the work feel real in a way that pace charts do not.
Local leaderboards create real accountability: A leaderboard filled with runners in your actual city hits harder than a global rank. You know those streets. Seeing a neighbor close in on your blocks is a pull that no training plan can manufacture, and runners consistently report going out for a Tuesday easy run specifically because someone was about to take what they built.
Free to start, works with any plan you already have: Motera is free to download. Open Runna or Hal Higdon for your workout, then start Motera to track the same run. Both run at once. You get the structure of a proven plan and the motivation of a game on the same session, at zero extra cost.
No plan to follow inside Motera: Motera has no training schedule. That is the point. It adds a motivation layer on top of whatever plan you already chose, with no conflicts, no duplicate calendars, and no decisions to make about which app to trust for your paces.
