Athlea Cycling · beta

A coach for your riding.
Indoor and out.

Structured indoor and outdoor sessions, a plan that adapts to your week, and your riding connected to your strength, running and recovery. Underneath, we're testing a more individual way to guide training: by metabolic state rather than fixed zones. Early days — join us.

Why we're building it this way
Experimental

Everyone gets the same zones.
Your body doesn't work to an average.

Most training is guided by a percentage of FTP — the same chart handed to everyone. It's a useful map. But the effort where you actually burn fat, or tip into lactate, is individual, and it moves with your fitness, your fatigue, and the day you're having. The physiology here draws on the work of Iñigo San Millán; the two ideas below are the reason we think it's worth building around.

Your metabolism is yours
The same 76% of FTP can be an easy spin for one rider and a grind for another. The intensity where your body changes isn't a fixed number — it's personal, and it shifts week to week.
Not all hard is useful
You adapt in specific metabolic states. Time spent in the right one builds your aerobic engine; a lot of time in the grey zone mostly just costs you. Training by state is about spending effort where it actually counts.
Zones aren't wrong
They're a sensible starting point, and we still use them. We just think beginning from your own physiology is a more individual way to get where zones are pointing — and sometimes a little further.

To be clear about where this stands: the science is real, our implementation is early and improving. We're going down this path because it's sensible — and we'd rather build it in the open, with riders and coaches, than pretend it's finished.

How a week fits together

Plan. Ride. Read.
Adjust, and go again.

The loop a coach runs with you — plan a block, ride the sessions, look at what happened, adjust. Some of this is here today; some is early. We've tried to be clear which is which.

01Plan

A block with a reason behind it.

Your cycling sits in a plan alongside the rest of your training, so a session has an intent — build the base, or sharpen — not just a number to hit.

02Ride

Guided, indoor or out.

A live ride screen walks you through the session with coach cues, segments and a debrief — riding to on-screen targets, on whatever setup you have.

03Read

Seen across your whole week.

Your ride is scored for training load and read alongside your other sports, so a heavy week doesn't blindside you and an easy one is on purpose.

04Adjust

The plan flexes when life does.

Slept badly, raced the weekend, legs flat? The plan bends around it — the aim is the honest dose, not forcing a number you shouldn't chase today.

05Repeat — and this is the early part

Learning your metabolic picture over time.

The part we're still refining: reading each ride by metabolic state, and tracking the equilibrium ceiling — the power you can hold in balance — as a personal number that should sharpen as you train. It's early, and it gets better the more people ride with us.

For riders

A bit of guidance on every ride.
Whatever kind of rider you are.

You don't need to be deep into numbers to get something out of it. Structured sessions, a plan that bends around your week, and your riding kept in the same picture as the rest of your training — whether you're spinning easy base miles or chasing a target.

Indoor or outdoor, one plan
Ride inside on the trainer or head out on the road — it's the same coached plan either way, not two apps that don't talk to each other.
Guided sessions, not just a timer
A live ride screen walks you through the session — segments, coach cues, and a debrief afterwards — riding to on-screen targets on whatever setup you've got.
It reads your gear
Pair a power meter, smart trainer, cadence sensor or heart-rate strap over Bluetooth and the ride screen shows live power, cadence and heart rate — recorded second by second into the debrief. Reading your trainer works today; telling it what resistance to hold is the roadmap item below.
Connected to the rest of your training
Your cycling is read alongside your strength, running, recovery and fuel, so your week adds up instead of pulling in different directions.
Scales to where you are
Targets are relative to your own fitness, so the same session works for a first indoor block and for someone with a race on the calendar.
Roadmap
Smart-trainer erg control — holding your target watts automatically — is something we're building toward. Join the beta and help us prioritise it.

Make it yours

Every session is a starting point.
Sculpt it, or just ask.

Sessions aren't fixed workouts. Open one and rebuild it block by block — add an interval set, choose the zone, set the recovery — or type what you want in plain language and let Athlea rework the session in place. Prefer to stay hands-off? Your plan tunes the next one from how this one went.

Block-by-block control
Intervals, repeats, zones, recovery — the same builder our session library is authored in, in your hands.
Or say it in words
"Make the intervals harder, 40 min" — describe the change and the session is rebuilt in place, structure intact.
Coached either way
Whatever you change, the ride screen still guides you through it segment by segment — and the debrief reads what you actually did.

Athlea Pro · for coaches

Your method, carried to your athletes.
Not more admin.

Your prescription shouldn't die on a spreadsheet. Athlea Pro lets you author a session once and deliver it to every athlete, right-sized to their level and FTP, with the metabolic-state thinking carried along. It's early — and we're building the coach side with founding coaches, not presenting it as finished.

Author once, deliver to each athlete
Build a session or a plan in Pro; each of the athletes you coach gets it, adapted to their level and threshold — your intent, their day.
The state model comes with it
Metabolic-state targeting (after San Millán's model) is part of Pro — early like the rest of it, and improving as coaches use it.
Erg delivery — on the way
Sending your watt targets to an athlete's smart trainer is on the roadmap. Today the session travels with your intent and on-screen targets; help us shape the erg side.
One connected view + a founding seat
See the athletes you coach across training, recovery and nutrition in one picture — and shape Pro and the library from the inside as a founding coach.
What's under it — honestly

The pieces we're building on.
Some solid, some still early.

A quick, honest inventory of what the coaching draws on. We'd rather show you the parts and their state than sell a finished engine.

A structured session library
Sessions authored across the range — recovery, base, threshold, VO2 — to real structure, not filler. A growing set, not a finished shelf.
The metabolic-state model Experimental
A 4-state view of effort (after Iñigo San Millán) and the equilibrium ceiling. This is the part we're actively refining — promising, not proven-out.
One load currency
Every session scored the same way and tracked as acute against chronic, so a heavy week shows up across your sports before you feel it.
Readable power profiles
A session drawn the same way every time, coloured by metabolic state — the same picture for rider and coach.
Grounded in the research
The physiology draws on published exercise science. Our implementation of it is our own — and early.

How it compares

Three ways to train.
Only one keeps coaching you.

A chatbot can talk. A cycling app can track and guide a ride. Athlea is built to do both — and to keep your riding in one picture with the rest of your training. Where a column earns its tick, we've given it.

Early access

Help us shape Athlea Cycling.

This is a small, early group. Riders get in first and steer what gets built next; coaches get founding access to Pro and a direct line to the people doing the metabolic-state work. What you tell us genuinely moves the roadmap — including which smart trainers we support first.

Questions

The short answers.

Is Athlea Cycling available yet?

It's in private beta. Join the beta and we'll bring you in as we open access.

Is it for indoor or outdoor riding?

Both. Guided sessions on the trainer indoors, and GPS-recorded rides outdoors — held in one plan rather than two apps that don't talk.

Do I need a smart trainer?

No. Today you ride to on-screen targets on whatever setup you have. Automatic erg control — a smart trainer holding your target watts for you — is on the roadmap, not shipped yet.

Which devices does it run on?

Athlea is iOS (iPhone) today; Android is on the roadmap. It syncs with Apple Health and connects to Garmin. Strava import isn't in yet — say so if it matters to you.

How does it handle my FTP and metabolic state?

Your FTP goes in at setup, and session targets scale from there. The metabolic-state read is the early, experimental part — it improves as we refine it. A lactate test can anchor it, but is never required.

What level is it for?

Everyone, casual to competitive. Targets are relative to your own fitness, so the same session works for a first indoor block and for someone with a race coming up.

Does it connect to the rest of my training?

Yes. Your cycling is read alongside your strength, running, recovery and nutrition, so your week adds up instead of pulling in different directions.

Can I use it with my own coach?

If your coach is on Athlea Pro, their sessions and plans flow into your app; if they're not, you can invite them. The coach side is early too, and we're building it with founding coaches.

Do I need a coach to use it?

No. It gives you a plan and guided sessions on your own — it just gets better when a coach is on the other side.

How much does it cost?

Pricing is not published while Athlea is in private beta. Join the waitlist and you will see the plans before anything is charged.
