The way points of this bicycle route:
Strat off the magnificent Albula passway.
Watch out, the last part of the decebnt, just after crossing the railway is pretty steep and ends at the busy Engadin road! And the passages here is narrow!
This is the turning point off the Alpen Challenge. Make your choice, is it short or loooooooong! turn right en it's off towards the Julier Passway, straight on the Bernina passway is waiting!
Forcola die Livigno!
Tunnel time, but no worries, it's open every 15 minutes, only one-way traffic! And....it's downhill from this side!
End off tunnel
Take the oneway entry. In the village first road take the right and the julier starts, and it starts steep!
The only place i ever saw a Marmotte during a cycling event. Did the "Marmotte" a few times, heard them, but here I saw them!
