Munich has many good running areas (not only for advanced but for beginners also)..
1) Englischer Garden ...anywhere...Beside the canal near Unterfohring is perfect for running. Since that covered bridge burned down, I haven't run here much.
2) Along
Isar near Thalkirchen (and on island). You can run all the way to Grunwald. You can even start near Deutsches Museum and run to Thalkirchen.
3) Along Nymphenburg canal in front of schloss and in park behind. There is a circuit right inside the park walls which is perfect. Take the long way around.
4) Ostpark is good...Some nice hills.
5) The park of Schloss Schleissheim... I used to live in Oberschleissheim and this place is also perfect. You can also run through the forest to Unterschliessheim.
6) Dowtown route (Neuhauser/Leopoldstr/Schelling/Augustenstrasse) is a good quick run.
7)
Olympiapark. ..is a nice evening circuit because it's lite well. The 'berg' also adds some difficulty.
8) For Beginners.. .The Old cemetery near Josephsplatz U-Bahn is good. The place is full of joggers...all the time. Once around on the inside is probably 400m.
