What is PaceGrid
PaceGrid is a free platform for runners and cyclists. It converts FIT and GPX files into Markdown ready for ChatGPT and Claude and replays the route in 3D with pace, heart rate and elevation. With an Amazfit, it streams workouts live and lets AI read your workouts and health data.
Frequently asked questions
Is PaceGrid free?
Yes, all of it. PaceGrid is built by one person and kept running by Pix donations, which pay for servers, maps and the AI APIs.
Does it work with Garmin, Coros or Strava?
Is my file stored on PaceGrid?
No. In the public tools the file is read in your browser and never reaches the PaceGrid database.
How do I stream a workout live?
Install the PaceGrid app on your Amazfit from the Zepp store and start the stream before you head out. Anyone with the link follows your route, pace and heart rate on the live map and sends cheers to your watch.
