How to generate a workout in ChatGPT and send it to a device
Chat writes the session. Based Training turns it into steps and sends it. Copy-paste into Garmin Connect is how you mis-count rest.
Short answer: ChatGPT will not talk to the watch. Connect ChatGPT or Claude to Based Training over MCP. Confirm the steps. Send to Wahoo or Garmin.
That is the job this page is about.
Use Based Training
Chat writes the session. Based Training turns it into steps you can see, then pushes to the Wahoo or the Garmin you already connected.
MCP is a how, not the product. Click-by-click for ChatGPT and Claude lives in the setup guide. ChatGPT still needs Developer mode. Based Training is not in the ChatGPT directory. Claude is the smoother MCP client today.
Look at the steps before you send. A hallucinated 3×15 executes if you push it. This is not a coach.
Same account can upload a finished Wahoo ride into Garmin Connect. Different pipe. See How to get a Wahoo activity into Garmin Connect.
Why copy-paste fails
A typical chat output looks like:
15 min easy, then 4×8 min at threshold with 4 min easy, then 10 min cool down.
That is a paragraph. Devices want sport, a step list, durations, and a target. Without that, you retype the session in Garmin Connect or the ELEMNT app. You will mis-count the rest interval. Everyone does.
Other options
Retype it in Garmin Connect or on the ELEMNT. Free, and you will skip it after a few Tuesdays.
PlanToWatch and RunSync send structured workouts to Garmin. Garmin only.
A hub like intervals.icu plus a custom GPT means you adopt intervals as the hub. Planned workouts can go onto a Garmin watch. That is not ChatGPT talking to the device by itself.
Self-hosted Garmin MCP is a thing if you want to run servers. Read-only Garmin connectors are not a send path. They can see the watch. They cannot put Tuesday on it.
TrainingPeaks, TrainerRoad, and Wahoo SYSTM have no ChatGPT send button.
If you hate assistants
Skip the chat. Generate in the app instead. The easiest way to generate a workout and send it to a device.
Honest limits
- Garmin sign-in is experimental. You log in with your Garmin email. The password is never saved. The path is unofficial and can need a reconnect. Read the privacy policy.
- Not a coach. The model does not know your life.
- Not medical advice.
- Not a promise that every exotic brick survives Garmin’s workout schema.
Bottom line
Chat writes. You confirm the steps. Based Training sends. Then go ride.
