4,380 m. The highest point reached on the route is 4,380 m, which is not the same thing - what your body has to adapt to is where you sleep.

There are 2 nights above 3,000 m where sleeping altitude rises by more than 500 m, which is more than the commonly cited guideline. That does not make the itinerary wrong, but those are the nights to look at first if you are adding spare days.
