Your first 30 days with the Suunto Vertical

Twenty minutes on the first evening. Everything the Vertical will tell you for the next month is built on a heart-rate trace, a satellite mode and a screen setting, and all three are decided here.

1. 1

   Put it where the sensor works

   A finger’s width above the wrist bone, one notch tighter than feels natural for the first week, sensor window clean. The Vertical has a 49 mm case and wants a wrist of about 167 mm or more to sit flat; on a smaller wrist it rocks, and a rocking sensor is the source of half the strange numbers in month one. See wrist and case size .

2. 2

   Set your maximum heart rate, or clear it

   Every zone, every training-effect score and most of the load figures hang off this one number. If you know it from a recent hard effort, enter it. If you do not, delete the age-based default rather than leaving it: a wrong maximum quietly miscounts every run.

3. 3

   Decide about multiband now

   The Vertical has multiband GPS. Under trees, between buildings and in steep valleys it is the accuracy that matters; on an open road it changes nothing and costs battery — 60 h of GPS becomes 60 h with it on. Pick one mode and leave it: switching between runs makes the pace history uncomparable. See multiband GPS: when it matters .

4. 4

   Turn the backlight down, not off

   The Vertical has a transflective screen: it is lit by the sky and costs almost nothing to leave on, which is most of why it exists. Set the backlight to gesture and the lowest brightness you can read; the quoted 60 h already assumes the screen is on.

5. 5

   Build one data screen you will actually read

   Pace, heart rate, distance, time. Four fields, one screen, big digits. Everything else can be a second screen you swipe to when you want it. The stock screens show too much and you will read none of it at speed.

6. 6

   Download maps before you need them

   The Vertical shows full topographic maps, and the tiles for your region are a download over Wi-Fi or the app, not something in the box. Do it on the first evening; it is slow, and the first time you want a map is not the time to discover it is missing.

7. 7

   Calibrate the altimeter once

   The barometric altimeter is what makes the elevation on a hilly run honest. Calibrate it once from a known height or from GPS on a clear day, and let it auto-calibrate after that.

8. 8

   Do not count the solar

   Solar charging is real and it is small: hours of direct sun add a modest slice of a day. Plan the battery as if it were not there, and treat what it adds as margin.

Suunto’s training analytics on the Vertical starts producing figures after the first run and the first night. These are the ones that arrive first, with what each one needs before it means anything.

• Training Load — a TSS-style figure per session and a rolling total, from the first run. This is the base everything else is derived from.
• Recovery time — after the first session, hours until the next hard one. Generic until the watch has your fitness level.
• Fitness level — a VO2max-style estimate after the first outdoor run with heart rate. It also feeds the “Progress” view in the app.
• Resources — a 0–100 reserve, similar in spirit to a body battery, from the first day. Its daily shape is more useful than its value for the first week.

The second layer of figures is where the Vertical earns its price, and where a new owner is most often misled — because each of them shows a value before it has the data to justify one. What follows is what each needs, on this maker’s system: the baseline takes about two weeks.

• HRV — overnight, needs about two weeks of nights before the app shows a personal range and starts flagging a night as unusually low.
• Training load over time — the app’s chronic and acute load views need two or three weeks before the chronic line means anything; before that every week looks like a spike.
• Sleep — from the first night, but the trends the app draws want a fortnight.
• Suunto Coach suggestions — they are built on the load history, so they are generic for the first couple of weeks and specific after that.

Suunto sits between Garmin and Coros: it has overnight HRV, but it does not compress everything into a single readiness score. The habit that works is the app’s Progress and Recovery pages once a week, and the HRV range whenever a morning feels off.

• A “low” HRV night is only low against your own range, which needs two weeks to exist. Ignore the first fortnight’s flags.
• Chronic load that keeps rising for a month is the window filling. Read it from the fifth week.
• Resources is best read as a morning-to-evening slope. A day that ends near where it started was a rest day whatever you did.
• The model cannot see illness or stress — see training load and readiness, and how much to believe .

Two figures on the Vertical are worth writing down at the end of the month, because they are the ones you will compare against later: the fitness estimate and, if the watch shows one, the morning recovery figure. Everything else is a snapshot.

These are the Vertical’s own figures, and the arithmetic the site’s battery guide applies to them. The quoted number is the best case; the settings you chose above decide which line you actually live on.

For a race, take a further fifth off for a cold day and then add your margin — or let the battery planner do the sum for the Vertical with your settings and your finish time. Everyday battery of 30 days means the charger is a weekly appointment at most.

The finder ranks the Vertical on the same figures this page uses. Its one-line verdict: Solar, maps, and a fortnight of mountains.

Where it is strong

• Free offline topographic maps for the whole world.
• Solar charging that pushes tour mode past a fortnight.
• Titanium, sapphire, and built in Finland.

What it gives up

• Heavy, and physically large.
• Training features trail Garmin and Polar.

If any of that is news after buying it, the finder will show you what the trade-off bought you — and what sat next to it in the ranking.
