Route
The only technical part is the descent from Selun which is T5. It's possible to drop out at any place. You'll just have to manage the max 1400m to the valley.

These are two good reports for the tour.

Time
The schedule will be very tight. So breaks will be very short. The pace will be slightly faster than 500m/h up and 1000m/h down. Doing this pace would result in 10hrs for the hike. So we'll need to be slightly faster for breaks and traverses.

3'700up at 500m/h -> 7:20
2'300down at 1000m/h -> 2:20
technical difficulty on descent from Selun -> 0:20
alltogether -> 10:00

Take some food that you can access and eat quickly. There is water refill after 1650m up at Torloch. For 4 of the peaks we'll be able to leave the backpacks at the bottom.
