React app that renders a realtime simulation for saved GPX workouts.
Step 1 is to export your Apple Health data, the instructions from Apple for this:
You can export all of your health and fitness data from Health in XML format, which is a common format for sharing data between apps.
Tap your picture or initials at the top right.
If you don’t see your picture or initials, tap Summary or Browse at the bottom of the screen, then scroll to the top of the screen.
Tap Export All Health Data, then choose a method for sharing your data.
I recommend AirDropping the files to your laptop.
Start the app with
npm i
npm run dev
Navigate to http://localhost:5173
Click the "choose file" button, then add in your GPX data. There are some sidebar controls:
- Click the timestamp to play/pause
- Drag the Playback Speed slider to increase or decrease playback speed from realtime up to 600x
