Nice banner; a good way to explore Munchen.
Had difficulty with the initial passphrase, but that's because I was being an idiot!
Hint: If you're not versed in the German language, use Google translate + look at the banner picture (or the actual Siegestor building!)
Took me longer than 2h 44m due to the hot midday sun.
Only a few major road crossings and most are safe enough.
I believe it is 24/7, but not 100% sure.
I don't think it would be as easy for those with a disability due to the need to use underpasses to cross major roads, some of which only have stairs as far as I could tell.

Amsonsen, schönes Motiv und schnell erledigt. Einfache Wegführumg.
