Enjoyed the heatmap when it was on raceshape and like it here as well!

Is this now the complete dataset from strava Run/Bike activities?

It has every public ride and run with activity id < 120,000,000

It's not updated on every upload, but pretty much the complete dataset.

Looks like id's went above 120m in early march. Does that mean activities after that aren't included?

Does it include premium account users' data?
