The first week with a new watch
Out of the box every running watch is configured for a hypothetical average owner. Ten minutes of setup is the difference between a tool and a nuisance.
Day one: the settings that matter
Set your maximum heart rate, or clear it
The default is 220 minus your age, which is a population average with a standard deviation of about ten beats. If you know yours from a hard race, enter it. If you do not, know that every zone the watch shows you is a guess.
Choose your GPS mode deliberately
Multiband if you run in cities or under trees; the cheaper mode otherwise. This is the single biggest battery decision you will make — see battery claims .
Build one data screen you will actually read
Three fields, not six. Most people want elapsed time, current pace and distance, and nothing else while running.
Turn off the notifications you do not want on your wrist
Email on a long run is the fastest way to stop wearing a watch.
The first few runs
Let it find satellites before you start, properly — standing still, outdoors, for a minute the first few times. A watch that has not downloaded its satellite predictions starts every run with a poor fix, and people conclude the GPS is bad when it is simply cold.
Wear it the way the fit guide describes and pay attention to whether the heart rate looks plausible. Fixing a sensor placement problem in week one saves a month of bad data feeding the training model.
By the end of the first month
- You will have enough data for load and readiness to mean something — see training load .
- You will know your real battery life in your real mode, which is the number that matters rather than the quoted one.
- You will know whether the strap suits you, and a €20 nylon one is the cheapest upgrade there is.
- You will have found the two or three features you use and quietly stopped opening the rest, which is normal.
Two things worth doing that nobody does
Set up the safety features
Incident detection and an emergency contact take two minutes in the phone app. If you run alone, on roads or in the hills, this is the most valuable thing your watch does and the feature least likely to be switched on.
Check what it is syncing
Every one of these platforms defaults to collecting more than you might expect, and the sharing settings are worth a read once. Your training history is fairly personal data and it is worth deciding deliberately where it goes.
What to ignore, at least for now
Modern running watches ship with more metrics than anybody uses, and the first week is when people try to use all of them. A short list of what to leave alone until you have a reason.
| Metric | Why to wait |
|---|---|
| VO2 max estimate | An estimate from heart rate and pace; the trend matters, the number does not |
| Running power | No agreed standard between brands, so it is not comparable to anything |
| Ground contact balance | Interesting, and no evidence that changing it helps |
| Race predictor | Assumes you have trained for the distance; it has no idea whether you have |
None of these are dishonest. They are all computed from real measurements. The problem is that acting on a number you do not have context for is worse than ignoring it, and week one is exactly when you have no context.
Come back to them once the training load and readiness picture has settled, which takes about three weeks of consistent wearing.
The part that decides whether you keep wearing it
Most running watches that stop being worn do not break and are not replaced. They end up in a drawer because of friction — something small and daily that the owner never got round to fixing.
| Friction | Fix | Takes |
|---|---|---|
| Charging is a chore | Charge while showering, not overnight | One habit |
| Notifications are noise | Allow calls and messages only | Two minutes |
| The strap irritates | A €20 nylon strap | One order |
| The data screen is cluttered | Cut it to three fields | Five minutes |
The charging one is worth dwelling on, because it is the only one people treat as fixed. A watch charged while you shower never interrupts anything and never runs flat; a watch charged overnight measures no sleep, which quietly removes half of what training load and readiness is built on.
None of this is about the watch being good. It is about it being unobtrusive, which is a different property and the one that decides whether the thing is still on your wrist in a year.
Questions readers ask
- Should I calibrate the barometric altimeter?
- It self-calibrates against GPS on most watches, which is fine for relative climb. If you care about absolute altitude, set it manually at a known point before a mountain day.
- How often should I update the firmware?
- Not the week of a race. Updates fix real bugs and occasionally introduce them, so take them a few weeks before anything important rather than the night before.
- Do I need the subscription?
- For the watches in this catalogue, no — Coros, Suunto and Polar charge nothing for maps or analysis, and Garmin’s paid tier adds coaching rather than core features. Check before you buy if a specific feature matters to you.
