Following a Course/Route on Map in App. Trail Running

Hi All

In the application Trail Running it is not possible to choose a predefined Route that I can follow on a map.

I can do this on Running, Hiking.

Especially on Trail Running it is important to sometimes follow a Track on the map. What I am doing wrong?

(Yes, I could use Running or Hiking instead, but I read that VO2 is calculated different in Running)

Thanky you very much for help
