Nine weeks, three runs a week
Running 5 km continuously is a fitness goal that a phone is unusually well suited to, because the whole problem is pacing and consistency and both are things software is good at. The standard approach alternates walking and running and shifts the ratio over about nine weeks. Almost every failure comes from starting too fast, not from picking the wrong app.
What the nine weeks look like
| Weeks | A typical session | What it is training |
|---|---|---|
| 1 to 2 | Alternating one minute running, ninety seconds walking | Getting out of the door three times a week |
| 3 to 4 | Three to five minute runs with walking between | Joints and tendons, which adapt slower than lungs |
| 5 to 6 | One continuous run of eight to twenty minutes | The confidence that continuous running is possible |
| 7 to 8 | Twenty five minutes continuous, slowly | Pacing, which is the actual skill |
| 9 | Thirty minutes, or the 5 km, whichever comes first | Nothing new; this week is a formality |
| Every week | Rest or a walk on the days between | Recovery, where the adaptation happens |

The apps worth having
A plain nine week couch to 5K plan with audio cues over your music. It does one thing, tells you when to walk and when to run, and does not need an account.
Free guided runs with a coach talking you through the session, which is the closest thing to company on a dark evening. Heavier on battery than a plain tracker.
adidas Running: a solid tracker with a large free tier, sensible graphs and interval sessions you can define yourself.
The social one. Segments and a feed are genuinely motivating for some people and mildly unpleasant for others, so try it before deciding.
Clear interval workouts and a long history of doing this well. A good default if you dislike the tone of the brand apps.
Strong route mapping and a large database of routes other people have run, useful in an unfamiliar area.
Steps and walking first, running later. The right starting point if three runs a week is still ambitious.
Sports Tracker: a straightforward tracker with no subscription pressure. The rating is mediocre, mostly for account and sync complaints rather than tracking.
Route planning off the pavement, with surface and elevation shown before you commit. For anyone whose 5 km involves a canal path or a hill.
Only worth installing if you own the watch, and large at roughly 400 MB. As a companion app it is excellent, as a phone tracker it is not the point.
The same caveat for Suunto owners: a companion to the watch rather than a reason to install it on its own.
And again for Polar. The app reviews poorly, the training analysis behind it is still among the better ones, so judge it as a watch accessory.
Download a playlist or a podcast before you leave. Streaming on mobile data mid run is a reliable way to arrive home with no battery.
A small reminder app for water, in about 17 MB. Unglamorous, and it matters more in the week of a race than any tracker.
Set the phone up once
- Download the audio before you go out Cues, music and podcast, all offline. A run that starts with a loading spinner usually does not start.
- Turn off battery optimisation for the tracker Aggressive battery savers pause GPS in the background and lose half a session. This is the most common tracking complaint on Android.
- Check the GPS has locked before starting Wait for the fix outside rather than in a doorway, or the first kilometre is recorded as a wander through a hedge.
- Put the phone somewhere that does not swing An armband or a belt. A phone in a jacket pocket produces a distance that flatters you and a pace that does not exist.
- Record the walking weeks too They are the training. A gap in the history in week two is what makes week three feel like starting again.
- Timing intervals and nagging you through them
- Recording distance, pace and a route accurately enough
- Downloadable audio coaching for free
- Keeping a history that shows the progression
- Telling you whether an ache is worth resting
- Measuring heart rate reliably from a camera
- Judging form, which needs a person or a video
- Knowing that you slept badly and should go easier
Where the app stops helping
Software is good at pacing and terrible at judging pain. A general ache that eases after a few minutes is ordinary early training; a sharp pain in one spot, or one that gets worse as you run, is the point to stop and, if it persists, to ask someone qualified. No tracker on the list can tell the difference, and none of them claim to.
If you have a heart or joint condition, or have not exercised for a long time, it is worth a word with a doctor before starting rather than after. That is the one piece of advice in this article that does not come from an app.
Pick one plan, run it slower than feels right, download the audio before you leave, and let the app do nothing except count.
Frequently asked questions
Do I need a watch?
No. A phone in a belt measures distance and pace well enough for a first 5 km. A watch becomes worthwhile when you want heart rate without holding a phone, or when carrying one stops being tolerable.
What if I miss a week?
Repeat the last week you completed rather than jumping ahead. The limiting factor early on is connective tissue rather than fitness, and it adapts on its own schedule.
Is running on a treadmill the same?
Close enough for the fitness, though GPS will record nothing, so use the app's indoor mode or the treadmill's own numbers. Outdoor running adds pacing and surface, which is why the last weeks are better done outside.
