How it works

Four links. All four are free.

1Lean Race Plan

Build your plan

FTP, hours per week, goal event. Two minutes later you have a periodised plan with watt targets for every session.

2ChatGPT or Claude

Connect your AI

Copy one URL from Settings into ChatGPT or Claude. From then on your AI can read your plan, your rides and your training load.

3In plain language

Let it coach you

"Legs are dead, make this week easier." Your AI moves, swaps or rewrites workouts in your calendar. You approve, it applies.

4On your device

Ride it

Every change syncs to your Garmin, Zwift or Wahoo as a structured workout. No exports, no files.

Coaching in your own words

No forms, no sliders. You tell your AI how the weekend went and what you want. It checks your training load and your last rides, changes the plan, and tells you what it did.

The changed workout is on your device before you close the chat.

Lean Race Plan connected
Legs are dead after Sunday's race. Make this week easier and move the threshold session to Thursday.
Your form is at −28 and Sunday was your hardest ride in six weeks, so an easier week makes sense. I swapped tomorrow's 4×8 threshold for 90 min Zone 2, moved the threshold session to Thursday and kept Saturday's long ride. Your calendar is updated.
Thursday's 4×8 threshold is now on your Garmin.

Why your own AI, not another app's

It already knows you

You use ChatGPT or Claude every day. It knows your tone, your language and your history. Now it knows your training too.

It sees the real numbers

Your AI reads your Strava rides, training load (CTL, ATL, TSB), planned workouts, weight goal and calorie targets before it answers.

It does the work

Not just advice. Your AI plans, moves, edits and deletes workouts in your calendar, and the plan stays the single source of truth.

It ends up on your bike

The workout it just changed is on your Garmin, Zwift or Wahoo within seconds, with warm-up, intervals and cool-down.

Frequently Asked Questions

What does this cost?

Nothing. The plan, the ChatGPT & Claude connector and the device sync are all part of the free plan, with no time limit and no credit card. You only need your own ChatGPT or Claude account. Pro (€6/month) adds a built-in AI Coach and the Smart Calorie Tracker for riders who would rather not bring their own AI.

Do I need a paid ChatGPT or Claude subscription?

Custom connectors are a feature of the paid ChatGPT and Claude plans, so yes, you need one of those. If you do not have one, the Pro AI Coach inside Lean Race Plan does the same job for €6 a month.

What can my AI actually do?

Read your planned workouts, your recent Strava rides with full power analysis, your training load, your profile, your weight goal and your daily calorie targets. And write: add workouts, move them, change duration or zones, mark them done or delete them, and adjust your weight goal or a single day’s calorie target.

How do I connect it?

Open the step-by-step guide under Settings: it generates your personal connector URL, shows exactly where to paste it in Claude or ChatGPT, and confirms the connection the moment your AI calls it. In Claude: Settings, Connectors, Add custom connector. In ChatGPT: Settings, Apps & Connectors, Developer mode, Create. That is the whole setup.

Which devices get the workouts?

Garmin Connect, Zwift and Wahoo receive planned workouts automatically through Intervals.icu, a free account that acts as the bridge to your devices. Every workout can also be downloaded as a .zwo or .fit file if you prefer to do it by hand.

Can my AI mess up my plan?

It can only change what you ask it to change, and every edit is visible in your calendar with an AI badge, so you always see what happened. Rides you have already done stay in your history. If you do not like a change, ask your AI to undo it or edit the workout yourself.

Is this the same as the Pro AI Coach?

Same calendar, same tools, different brain. The free connector lets your own ChatGPT or Claude do the coaching. The Pro AI Coach is built in, reviews your training every day and needs no setup. Many riders use both.
