Fascinating when you pull out with the map to see the whole of Europe. The UK lights up like a Xmas tree as well as Belgium and the Netherlands. The rest of Europe has only small dots around the main conurbations.
220 billion GPS coordinates meshed into a global heat map of Strava activity – works out at about 78 million bike rides apparently!
Zooming in on the UK you can see the outline of Richmond Park and Box Hill stands out as a bright blue dot. Glentress, Innerleithen, Cannock, Gisburn all stand out really well and you can make out some Sportive routes too, especially the Etape Caledonia.
Have a look at Moab, Utah. You can clearly make out Slickrock Trail and Porcupine Rim. Porc Rim is the one which seemingly starts in the middle of nowhere due to most people getting an uplift to the trail head.
