hiking-pace

Visualise your actual hiking pace vs slope from GPX tracks, compared to the theoretical Tobler hiking function.

Live demo →

What it does

Drop one or more .gpx files onto the chart. For each track the app:

• Segments the route into chunks of at least 25 m
• Plots your actual pace (min/km) against slope (%) for each segment
• Fits a polynomial regression curve to your data
• Shows the theoretical Tobler curve in grey for reference

Useful for understanding your personal pace model or comparing multiple hikes.

Usage

1. Open the live demo
2. Drop one or more .gpx files onto the chart area
3. Hover a track name to highlight its data points
4. Click Save as PNG to export the chart

Run locally

npm install
npm start

Then open http://localhost:5173.
