Frequently asked questions
How do I analyze my Strava workouts and data in ChatGPT or another AI?
To analyze your Strava workouts with AI, export the original activity from Strava (as .FIT or .GPX), drop the file into PaceGrid to generate the structured summary, and click 'Copy for AI'. Then paste the generated text into ChatGPT, Claude or Gemini. You can ask things like: 'Analyze my pace and heart rate zones in this workout and suggest how to lower my 5K time' or 'Assess my fatigue level'.
How do I convert a FIT file to GPX, CSV or JSON?
Drop the .fit file into the PaceGrid converter and pick a format: GPX (maps, Strava and bike computers), CSV (Excel or Google Sheets), GeoJSON (web maps) or JSON with every record. Conversion runs in your browser and needs no account.
Can I analyze workouts without exporting files?
Yes, if you use an Amazfit watch. With a free account and Zepp connected, every activity syncs on its own with history, heart rate zones, records and 3D replay. For other watches, exporting the .fit or .gpx is still the way.
How do I convert a FIT file to Markdown for ChatGPT?
Drop the .fit into the PaceGrid converter, choose AI Markdown and copy it. The output has the summary, laps, pace, heart rate and elevation in tables, a format ChatGPT, Claude and Gemini read better and with fewer tokens than raw JSON.
How do I export the FIT or GPX file of a Strava workout?
On Strava, open the activity on the website from a computer, click the gear icon (Settings) in the left sidebar and choose 'Export Original' (for the original .FIT file) or 'Export GPX'. You can also bulk-download all your Strava data from your account's privacy page.
How do I get the FIT or GPX file from a Garmin workout?
Open the Garmin Connect dashboard on the web, go to your activity list and select the workout. In the top right corner, click the gear icon and choose 'Export Original' (which downloads a zip containing the .fit file) or 'Export to GPX'.
How do I export activities from Amazfit and Zepp watches?
Open the Zepp app on your phone and tap the 'Profile' tab, or tap a recent activity to open it. Go to the activity options (the share icon or the three-dot menu at the top) and choose 'Export route'. You can then save the .gpx file straight to your device.
Can I import a FIT file without a GPS track?
Yes. Treadmill, indoor trainer, strength and other indoor workouts work. Without a map you still see calories, heart rate, cadence and power, and you can copy the Markdown for AI.
What is the difference between GPX and GeoJSON?
GPX is the standard XML format for GPS (version 1.1), accepted by Garmin, Strava and bike computers, with tracks, routes and waypoints. GeoJSON is a lightweight JSON format built for drawing and handling routes on web maps.
Want your workouts to arrive on their own?
With a free account and an Amazfit/Zepp watch, every workout syncs by itself, with personal records, a 3D map and an AI coach.
