athletedata vs stats.training

Two products, same starting idea: your training data should live inside the AI you already talk to, not behind another dashboard. They go about it differently enough that the right pick is usually obvious once you know what actually separates them. Here's the comparison, written by one of the two, with the parts where the other one wins left in.

What athletedata actually is

athletedata.health launched in spring 2026 and sells two things. The €9/month MCP plan connects your accounts and exposes them to Claude or ChatGPT. The €33.90/month coaching plan adds an AI coach that writes a rolling two-week plan, rewrites it when you miss a session or sleep badly, and messages you first over iMessage, Telegram, or WhatsApp.

The integration list is the headline: Garmin, Wahoo, Polar, COROS, Suunto, Zwift, TrainerRoad, Intervals.icu and TrainingPeaks for training, WHOOP, Oura, Apple Health and Withings for recovery, Hevy and Strong for lifting, Cronometer and MyFitnessPal for food, plus calendars. If your training life is spread across five apps, that breadth is the product.

Where athletedata genuinely wins

It can write to your watch

This is the real one. athletedata pushes structured sessions into Garmin Connect, so tomorrow's intervals show up on your watch ready to start. stats.training is read-only by design and always will be. It can tell you what to run; it cannot put it on your device.

Breadth

Thirty-odd sources against our two. If you lift in Hevy, log food in Cronometer, and want all of it in one conversation, that isn't a close call.

It connects through Garmin's official program

athletedata is an approved Garmin developer, so connecting is an OAuth redirect: you click through on Garmin's own site and you're done. That path is more durable than any third party's. It's also a door Garmin has effectively stopped opening to new applicants, which is why almost nobody else has it.

A coach, if you want one

The coaching tier is a genuinely different product from anything we do. It's opinionated, it follows real methodology, and it chases you. Some people want that. We don't build it.

Where stats.training wins

It works where you already chat

Your stats.training link carries your key inside it. That means you paste one URL and it works in Claude on the web, Claude on your phone, Claude desktop, and ChatGPT. Connectors that authenticate with a custom header can only be added in a desktop app, which rules out the two places most people actually open Claude.

If you've ever wanted to ask about last night's sleep from your phone on the way to a run, this is the difference that matters, and it's the reason most of our customers came over.

Depth on Garmin specifically

We expose 33 separate Garmin tools: sleep stages, HRV status, Body Battery and its events, training readiness, training status, endurance and hill scores, lactate threshold, race predictions, VO₂ max, respiration, stress, floors, intensity minutes, personal records, body composition, blood pressure, strength sets, per-activity weather and splits. A connector covering thirty sources is by nature shallower on any one of them. If Garmin is where your data lives, depth beats breadth.

Read-only, nothing kept

We never store your health history. Data is fetched when your AI asks and passed straight through. Nothing can be written back to your account because nothing is built to write.

Strava in the same link

Garmin and Strava both, one connector, no second subscription.

The connection method, honestly

athletedata sends you to Garmin's site to authorize. stats.training asks you to sign in with your Garmin account directly, the same credentials you use in the Garmin app, stored encrypted and used only to fetch your data.

Theirs is the cleaner mechanism and we won't pretend otherwise. Ours occasionally asks you to reconnect, usually after a Garmin-side change or a password reset, and we email you when it does. That's the trade for a connector that works on your phone. Worth knowing before you pick.

Side by side

Which one to pick

Pick athletedata if you want a coach rather than a connector, if your data is scattered across several apps, or if having tomorrow's session appear on your watch is the whole point.

Pick stats.training if Garmin is where your training lives, you want to ask it things rather than be told things, and you want that to work on the phone in your pocket. It's a smaller promise, kept well.

The questions people actually bring us look like this:

Neither product locks you in. Both are monthly, both cancel in a click. If you're genuinely torn, the cheapest way to settle it is to try the one whose weakness you can live with.
