This route is generally suited for a 2-day hike, however, it can be done in one day (approx. in 12-14 hours) by hikers in good physical condition carrying light backpacks. If you decide to do so, expect it to be extremely exhausting.
For a 1-day hike, it is strongly recommended to start the loop from the eastern (Shovi) side as it includes a very steep approach to Geske Pass which should be easier on the way up rather than on the way down. In additon to that, a great part of the eastern side of the route is not prominent which will make it hard to navigate on the way down to the forest (basically, the trail does not exist anymore in some parts of the route on the east so you just have to follow the direction).
