Technical and physical requirements

A good preparation is necessary, this climb is meant for sportive people. Prepare yourself practicing “cardio” endurance sports like biking, hiking and running.  Don’t forget that you’ll be walking with a 8kg backpack at high altitude, which is more physical than without, so don’t forget to train with the extra weight.
