Strava, one of a number of services that walkers, runners and cyclists can use with their smartphones, recording and uploading their routes, has released a heatmap showing the activity uploaded to the network on Saturday 20 July. Zooming into London reveals many tracks. By default it shows cycling uploads, with a toggle for routes on foot.
There is a sizeable pulse heading NE from Hackney, when viewing the visualisation for the evening hours. This is the Dunwich Dynamo, a 120-mile free sportive, that takes place overnight once a year, where upwards of 1000 cyclists head out of London, towards the Suffolk coast. As such, despite Strava’s claim on the site, it was anything but a typical Saturday. (Note also that the map possibly normalises based on activity, so that when the Dynamo starts at around 8pm, other cycling activity in London is less prominently represented. Or maybe that’s just because it’s starting to get dark…)
It’s a nice visual, although an aggregated view across several Saturdays, or several weekdays, would provide a more representative graphic of London’s activity hotspots and popular recreational routes.
