Strava Heatmaps Explained: Global, Personal, and Weekly Route Planning

Strava Heatmaps visualize aggregated GPS data from millions of athletes worldwide, turning popular routes into bright glowing lines and obscure trails into faint traces. The brighter the line, the more activity logged there. It is one of the most practical free tools available for route discovery, and it works across running, cycling, and trail sports.

Strava offers four distinct heatmap modes. Global shows the crowd-sourced density of all activities. Personal reflects your own history, useful for spotting gaps in your training geography. Night mode renders everything on a dark background, making the contrast between busy and quiet routes easier to read at a glance. Weekly heatmaps let you track where you have been in a rolling seven-day window, which is genuinely handy during travel or race week recce runs.

Compared to Garmin Explore and Komoot, Strava Heatmaps win on raw data volume. Garmin Explore leans on curated routes and Topo maps, which suits structured navigation better. Komoot excels at turn-by-turn routing with surface type filtering. But neither matches Strava for showing you where real athletes actually go, especially in urban areas or on popular trail networks like those around Chamonix or the Alps.

The main limitation is that heatmaps reflect popularity, not quality. A busy road segment glows just as bright as a perfect trail. In remote areas or developing regions, data is thin and the map goes dark fast. Strava Summit (paid tier) unlocks full global heatmap resolution. Free users get a lower-resolution version, which is still usable but loses fine detail on singletrack.

Solid tool for route scouting. Not a replacement for navigation apps. Use it alongside Komoot or Garmin Explore for the full picture.
