Garmin in ChatGPT. One link, every chat.
ChatGPT Pro now supports custom connectors. Add the stats.training link in Settings → Connectors, give it a name, and from then on every ChatGPT conversation can read live Garmin data: sleep, HRV, training load, runs, races, the lot.
Three steps in ChatGPT.
- Open chatgpt.com › Settings › Connectors.Custom connectors require ChatGPT Pro. (Free / Plus tiers will get there eventually; Pro is where it lives today.)
- Click "Add" → "Custom Connector".Name it whatever you like, paste the stats.training link.
- Save and start a new chat.The Garmin tools show up in the connector list. ChatGPT will call them automatically when your question warrants it.
The model you already use, with the data you actually have.
If ChatGPT is already your daily driver, the friction of switching to a separate fitness AI is what kills you. Connectors mean ChatGPT itself becomes the analyst, instead of you exporting CSVs.
What this pairing is best at: structured reports and planning. ChatGPT is reliable at producing tables, week-by-week training plans, and "compare A to B" analyses. Pair that with live Garmin numbers and you get genuinely useful output: a five-week marathon block tailored to your current race-prediction time, or a side-by-side comparison of last month's HRV vs this month's, or a target-pace breakdown for breaking 45 in the 10K.
First questions in ChatGPT.
ChatGPT-specific questions.
Do I need ChatGPT Pro?
For custom connectors today, yes. OpenAI is rolling support out gradually; check your connectors settings to see if your tier has it. Once it's available, the setup is identical to Pro.
Does this work in the ChatGPT mobile app?
Yes. Once the connector is added on chatgpt.com web, it's enabled across iOS, Android, and the desktop app. Same Pro account, same data.
GPT-4, GPT-5, or which model?
Any model that ChatGPT lets you pick will use the connector if you have it enabled. The smarter the model, the better it is at chaining several Garmin tool calls into one coherent answer.
Will OpenAI see my Garmin data?
Your training data is read directly into the conversation context for ChatGPT to answer. Standard OpenAI privacy policies apply (you can disable training-on-chats in settings). We never store your activities or sleep on our side, only the encrypted token that lets ChatGPT fetch it on demand.
