Garmin knows how far you ran. It doesn't know how worn down you are

For years I read the Garmin app like a report on myself. Heart rate, sleep, HRV, weekly load, training readiness — all neatly counted. And still there were days when the numbers said go and I knew I shouldn’t.

The difference was always the same thing. The week a project was on fire. The night up with a kid. The flight the day before. The conversation you can’t sleep after. My watch knew none of it — and that was usually what decided how the session went.

That’s how Menteora started. It handles exactly what stayed off the record: your stress.

Stress isn’t what you think it is

The word has been worn down to mean “had a rough day at work”. Stress is any demand on the body that it answers by mobilising — hormones, nervous system tone, spending your recovery budget.

The key part: the body doesn’t sort by source. A hard tempo run, a deadline, short sleep, a conflict, a time zone change, an illness coming on — it all goes into one pot. Your body doesn’t keep a separate ledger for athletic fatigue and life fatigue. There’s one ledger.

Which leads to the thing that breaks most plans: training doesn’t make you fitter — recovering from it does. And recovery draws on the same budget everything else is spending. The same session on a fresh background builds you; on a loaded background it digs a hole.

That background is what your watch can’t see. It counts training load honestly and tells you how your body handled the running. On the other ninety percent of your life, it has no data.

Measuring what can’t be measured

Stress can’t be read off a wrist sensor. But it can be read off you — if you’re asked regularly, and asked the same way.

A short check-in in the morning: how you slept, how you feel, what’s going on in your life. Under a minute. In the evening, optionally, another one — how the day went and how the session felt.

Every answer becomes a number. Not “mood”, but concrete measurable pieces of the background: sleep, how you feel, outside load, recovery. Day after day they build a series — a numerical history of your stress that simply didn’t exist before.

That’s the self-diagnosis part. Not “listen to your body” — an actual series you can look at, compare, and watch move.

How Menteora works

After a few weeks you have a personal baseline — what your stress and recovery usually look like. Not a benchmark for everyone: comparing yourself to an average person is pointless, everyone has their own working range.

From then on, each new day is compared to that baseline. Not to an abstract scale, but to you two weeks ago. The deviation, up or down, is the signal.

Menteora also picks up patterns: the days, situations and circumstances that consistently cost you recovery. You usually half-know about these already. The bot shows them as an observation — not a diagnosis, just a fact from your own data.

We don’t bend the numbers to make a nicer picture. The model is deterministic and the same for everyone: what it says today is what it will say tomorrow given the same inputs. No magic, no “the bot read my mood”. Just arithmetic on what you reported yourself, plus what Garmin sees.

Stress, turned into a decision

Measuring the background is half the job. The other half is what to do about it this morning.

Menteora puts two things together: training load from Garmin and your stress background from the check-ins. And it answers the one practical question — how hard you can afford to go today.

Background high, recovery unfinished — the bot flags it and suggests dialling the intensity back, even when the plan says hard session. That’s not concern in general, it’s a concrete reason not to walk into intervals on a bad day.

Background normal, budget available — the bot tells you today is a good day for quality work. Not “take it easy just in case”, but a decision, because the data supports it.

Menteora doesn’t argue with your plan and doesn’t replace your coach. It adds a variable the plan never had — your state today, all of it, not just the running part.

What else is in the bot

• AI coach note — a short read on top of the numbers: what to keep in mind today, what to look at.
• Weekly report — how your background moved over the week, where it dipped, where it climbed.
• Streaks — check-in consistency directly affects how accurate your baseline is, and the bot keeps an eye on it.

Who it’s for

For people who train seriously while living an ordinary life: work, family, flights, short nights. Who have a Garmin and a plan, but no answer to “am I actually up for this today”.

Garmin sees the body. Menteora sees the person.
