Your first 30 days with the Suunto Race S

Twenty minutes on the first evening. Everything the Race S 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 Race S has a 45 mm case and wants a wrist of about 153 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 Race S 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 — 40 h of GPS becomes 30 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

   Choose gesture or always-on, and mean it

   The Race S has an AMOLED screen. Always-on is the single biggest drain after the GPS chip — the site’s battery guide takes a fifth off for it — and gesture mode is what the quoted 40 h assumes. Try gesture for a week before deciding it annoys you.

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 Race S 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.

Suunto’s training analytics on the Race S 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 Race S 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 Race S 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 Race S’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 Race S with your settings and your finish time. Everyday battery of 9 days means a charge roughly once a week.

The finder ranks the Race S on the same figures this page uses. Its one-line verdict: The Race, shrunk to fit a normal wrist.

Where it is strong

• Offline topo maps and multiband under €350.
• Forty quoted hours of GPS.
• A digital crown that actually works with gloves.

What it gives up

• No music or payments.
• Nine days of everyday battery.

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.
