Most running apps show you data.
baseline tells you what it means.
Understand what's actually happening in your training — and what to change next. For runners who want clarity instead of more numbers.
You already have the data.
That's not the problem.
Strava captures every kilometre. The questions that actually matter live somewhere else.
Three things, in order.
Not a training plan. Not another dashboard. A coaching layer that watches the signals across weeks, understands the pattern, and tells you — plainly — what to do next.
Patterns in your runs
Drift, effort creep, recovery gaps, weekly balance. Watches capture these — they rarely connect them.
What they actually mean
In plain language. No heart-rate zones with cryptic colours. No compliance score. What's happening, why it matters, what it's costing you.
What to change next
One call for today. A clear reason behind it. No generic 'rest day' or 'hard workout' — a specific decision for the runner you actually are.
Things you've probably never been told about your own running.
The reads a sharp coach would give you — if one watched every run. A problem you can't feel, a gain you can't see, a strength worth keeping. Three baseline has actually written.
Your easy runs are drifting
HR climbs ~5% after 30 min while pace holds steady
At your usual easy HR (135–145 bpm), your pace held — but heart rate climbed steadily through the back half of the run.
Drift on easy days means the run isn't doing easy-day work anymore. The aerobic stimulus is paid for; the recovery savings aren't being banked.
The drift you can't feel.
Easy runs are supposed to leave the body recovered, not just untired. When HR climbs while pace holds, the effort is creeping up — invisibly.
baseline reads HR drift across runs and only flags it when the pattern holds for a stretch — never on a single noisy run.
You're faster at the same effort
Same paces, lower heart rate, across your recent easy runs
At your usual easy effort, your pace has been climbing — the same heart rate is buying more speed than it did a few weeks ago.
That's real aerobic fitness arriving — the kind that shows up weeks before a PR does. The base work is paying off.
Fitness, before it shows as a PR.
Fitness rarely arrives as a personal best. It shows up first as the same pace at a lower heart rate — over weeks, not days.
baseline tracks the trend behind the trend, so you know it's working before a race day ever proves it.
Your easy engine runs deep
HR holds in the easy zone past 30 min, across your long runs
On your longer easy runs, heart rate settles and stays there — no climb through the back half, run after run. The aerobic base is doing its job.
This is the engine everything else is built on. A base this steady is what lets harder work land later without breaking you down.
Strengths get named, too.
Most coaching apps only flag what's broken. baseline names what you're doing right — those patterns are the foundation the harder work gets built on.
When something is working, the call is simple: keep it. We'll tell you that, too.
Connect once. baseline does the rest.
Connect your data
One tap. Whatever you already use — your runs come across with their history intact, not starting from zero.
baseline learns you
Your imported history means baseline reads your patterns from the start — no waiting. Each new run sharpens the picture, always read against your recent weeks. Patterns matter more than any single run.
You get one call a day
Read it in the app, or as a morning email if you want it. Plus the occasional key insight when something genuinely matters. No daily readiness score to decode.
The gap everyone else leaves empty.
Stop guessing.
Start understanding your training.
baseline is in closed beta. We're adding runners weekly, reading their data, and writing back. If you take running seriously and want clarity, tell us.
