Gravel heatmap shows only routes from races?

[victoo]

Gravel heatmap it is not working properly. IMO it shows only gravel rides sets as a RACE. Why?
I live in gravel area, but on heatmap is shows only routes of two local gravel races.

UPDATE FROM SUPPORT: 
Note: this is regarding Global Heatmaps opposed to Personal Heatmaps.
 
There are several reasons that there may not be data showing in the heatmap area you specified, most of them are related to user privacy. A certain amount of public data from several users is needed to allow our heatmap to show any heat in an area. Please see our Help Center article on the global heatmap for more information.
