Build your own personal training heatmap

A heatmap overlays all your outings on a single map: the roads you use most light up. It's both satisfying to look at and useful for spotting your habits or the corners you haven't explored yet. Here's how to generate yours from your own files, without relying on a subscription.

What is a personal heatmap?

It's a map that aggregates several activities: the more often you pass a spot, the stronger the track is drawn there. Unlike platforms' global heatmaps, a personal heatmap shows only YOUR outings — your playgrounds, your favourite loops, the areas left to discover.

How to generate it

  1. 1

    Gather your files

    Export your activities from your watch or platform (GPX, FIT or TCX).

  2. 2

    Open the heatmap tool

    Drop several files at once into the drop zone.

  3. 3

    Explore your map

    All your tracks overlay; your recurring routes stand out immediately.

Build my heatmap

Your activities stay on your device: nothing is sent to a server, no account required. It's your map, private.

Get your activities ready

Files in a format the tool won't take, or want to check an outing first? Convert them or open them in the viewer before building your heatmap.
