chota char dham trekking

Hi,
I will do the Chardham by feet. But i canīt find in Internet the route. I only find the route between gangotri and kedernath, the old yatra road between mala and trijuginarayan. I walk this part in 6 days in june, It was amasing.
Now im lokking for trekks between jamunotri und gangotri and between kedernath and badrinath.
There is a foodpath from Hanuman Chatti by Bamsaru Khal to Sukhi and then road again to gangorti. But is this the way pilgrims do in old days????
Between Kedernath and Badrinath I only find street. But to walk 200 km along street is not very nice.

Maybe someone can help me?
Maybe someone is interest in going such ways together
