Route planning
The route planning took several weeks with countless changes and corrections. We then started a meticulous Excel spreadsheet that recorded all the relevant waypoints, emergency and mountain huts, supply options and, above all, mountain stations.
An important point, because carrying supplies for 20 days plus emergencies would have made the rucksacks too heavy for walking. After several tests, the planning (as of June 2025) envisages a maximum weight of 9 kg per person.
The route planning assumes two days of self-sufficiency in most sections. Intermediate supply options are a nice add-on with treats.
