For athletes who train for more than one thing
Your training data is fragmented. Your goals aren't.
Connect your training plan, your workouts and your wearables. Octane turns them into one picture of what you're training for, how you're responding, and what should change next.

The problem
Seven apps. One athlete.
Garmin knows your run. Oura knows your night. Runna knows your plan. Your strength session knows nothing about any of them. Each one sees part of you. None of them has the context.

What should I do today?
Your apps have data. They don't have context.
- Running plan app
- Knows the plan.
- Wearable
- Knows its own sensors.
- Nutrition app
- Knows what you ate.
- Octane
- Reads them together, and says what changes.
Nothing is replaced and nothing is written back. Octane reads from the apps you already use.
Wearables disagree
Garmin says one thing. Oura says another.
Two devices scored the same night and disagreed by hours. Octane didn't average them and didn't pick a favourite. It read the record that saw more of the night, and said so.
One night, two records
Oura

ReadGarmin watch, through Apple Health

What Octane read
Connect (chosen of 3 — also Garmin, Oura)
“Oura recorded 3 h 39 min asleep against Connect's 6 h 5 min — the shorter record likely missed part of the night, so the longer one was read.”
Why row: Sleep · 6h 5m
A preferred source is set aside only when another record is at least 45 minutes longer — in sleep and in the stretch of night it covers.
Then the decision reads the night against your own baseline, never a vendor's score. The Why row says which one applied: “vs your baseline” while it forms, “vs your own spread” once it's trusted.
A difference is not a fault. Which record Octane reads is a rule about what a device saw, never a verdict on which device is right.
More than one goal
HYROX in October. Marathon in December. One athlete.
One season, several dated events. Octane knows which one comes first without forgetting the one after — and says out loud when two races sit too close to both get a taper.
The season, as the planner cut it
- Oct 24 · HYROX Miami A
- Dec 6 · CIM A
- Apr 18 · Spring half A
- HYROX MiamiHYROX specific build · Peak · Taper · Race · Recovery
- CIMCompressed by a neighbouring race.Marathon specific · Peak · Taper · Race · Recovery
What the planner says
- “HYROX Miami is 14 days after Half — planned as a B race, its row unchanged.”
- “Spring half is beyond the 182-day horizon and is listed, not planned.”
- “CIM is a B race: raced, not tapered for.”
- “Taper: sharpening, not building.”
- “Race week: short and sharp, nothing that costs.”
Pro. Already on a Runna plan? Octane reads it as before. A season is something you generate, never something that replaces your plan unasked.
The loop
Your plan should learn from you.
A plan tells you what to do. Octane reads what you did against what was prescribed, says what the session showed, and tomorrow's decision reads what it cost.
1 · Plan
What the day asks — from Runna, a coach's calendar, or a season Octane laid out.
2 · Perform
The session, as your watch recorded it — laps, heart rate, the lot.
3 · Measure
Each lap lined up against its step, each run against your own comparable runs.
4 · Compare
Prescribed against actual, in words: executed to plan, came in short, faster than the range.
5 · Adapt
Tomorrow's decision reads the morning after. Only ever the plan, or less.
A tempo, read
Prescribed · warm-up 1.5 mi · tempo 3 mi @ 8:20–8:50/mi · rest 2:30 · cool-down 1 mi

STRONG EXECUTION — ELEVATED RECOVERY COST
What happened
- Tempo miles: 8:32, 8:22, 8:12 — each faster than the last.
- Executed to plan — 97% of the planned distance.
Why
- Across the tempo miles, heart rate climbed from 167 to 183 bpm while pace moved from 8:32 to 8:12.
What changes
- Tomorrow: Tempo / intervals — one of the week's key sessions. Octane re-checks your recovery in the morning.
Training advice only ever suggests doing less, never more.
Life changed
Life changed. Your plan should too.
Four hours of sleep, a check-in that says “off”, and a key session two days away. Octane doesn't pretend the plan is the same plan. It says what today should become, in the plan's own units.
This morning
Planned: Easy run · 5 mi
Thursday: VO2 intervals
- Sleep
- 4h 40m caution
- How you feel
- Feeling off · poor sleep caution
The decision
SHORTEN
Cut the volume today
Keep the session, shorten it. The intensity is not the problem here.
“Sleep and your check-in sit outside your usual range; today asks for less.”
- 4h 40m last night.
- You said: feeling off · poor sleep.
- Today is the cheap day to absorb this — VO2 intervals on Thu Sep 17 is the one worth protecting.
Instead
5 mi → 3.5 mi, same pace
- Run 3.5 mi instead of 5 mi, at the planned pace.
And if you'd rather move it, move it: any Octane session can be moved, skipped or restored from the plan, and a watch that receives Octane's sessions follows.
Octane never moves a session for you, never adds one, and never reads an illness into a bad night.
Station by station
Know where the race is getting away from you.
Your watch recorded one long workout. Octane reads it as eight runs and eight stations — each station against your own earlier sims, and the late runs against the early ones.

Band figures are coaching practice, not a measurement.
Free: the table. Pro: the comparisons against your own sims and the run-fade line.
It never ranks a station as a weakness and never says why a split was what it was.

Either way the morning decision is the same: the day as planned, or less.
One body
Your body doesn't separate these systems.
Neither should your training software. Training, recovery, fuel, water and what you take sit on one timeline, and the decision reads all of them.
Training
The plan, the session, the read.
Recovery
The night, the morning after, your own baseline.
Nutrition
Fuel windows that know tomorrow's session.
Hydration
Water against your target, a nudge only when you're behind.
Stack
What you take, on the same timeline, as medians with the confounds beside them.
Tomorrow isn't a normal day
Tomorrow: Long Run • 16mi · 150 / 375 g carbs today
The day before a long run of this size asks for 400–560 g of carbohydrate at your bodyweight — a band from the literature, beside your own target.
- Pre-run fuel · 46 / 70 g carbs · by 7:00
- After your session · 12 / 40 g carbs · 26 g protein
Why this exists
The existing stack wasn't enough. So I built the layer above it.
I run a Runna plan, wear a Garmin on the run and an Oura ring at night, and I train for more than one thing at a time — a marathon in December, hybrid work through the autumn. Each app told me something true. None of them talked to the others.
The morning after a hard session my ring said one thing, my watch said another, and my plan said the same thing it always says. Nothing read them together and told me what today should be.
Octane is that read. I'm building it with the first 500 athletes rather than for them — every recommendation has a thumbs down with a reason, and I read every one.

Why not…
Can't I just put my data into ChatGPT?
Can't I just put my data into ChatGPT?
You can hand a general model whatever you paste in. Octane is built around your continuously connected timeline — your goals, your plan, your workouts, your wearables, your recovery, your nutrition, and what happened after each earlier recommendation. It reads that every morning without being asked, and every number on the screen comes from a deterministic engine, not a model.
Doesn't Garmin already do this?
Garmin is one of the best sources Octane has. It knows your run and, if the watch stays on, your night. It doesn't know your Runna plan, your ring, what you ate, how you said you feel, or that Sunday's long run is the one worth protecting. Octane reads Garmin in that context.
What if I already use Runna?
Keep it. Octane isn't asking you to throw away a plan that works. Paste the calendar link and Octane reads every session, matches what you ran to what was planned, and reads the morning after — without touching the plan.
How is it different from a readiness score?
A score summarises one device's view of one morning. Octane's decision is about a specific planned session: it knows tomorrow's long run is the one worth protecting, what you ate yesterday, how you said you feel, and what you've started taking. And when nothing was measured, it says that, rather than showing a number built on one input.
Will Octane move my intervals to another day?
Not on its own. When a morning asks for less, Octane says what today's session should become — shorter, easier, or a recovery day — in the plan's own units. Moving a session is yours: any Octane session can be moved, skipped or restored from the plan, and a watch that receives Octane's sessions follows. Sessions from Runna or another plan are moved in their own app.
What's free, what's Pro, and what does it cost?

The decision, its label, its sentence, the Why rows and every number on the screen come from deterministic engines reading your own data. A model writes the morning brief and reads meal photos — and any text carrying a number Octane didn't supply is rejected.
