Ask yourself: do you practice endurance sports (running, cycling...) ? Are you used to hike for several days, and on such long distances ? If you hike, are you used to hike on steep, rocky terrain, with a daily ascent of minimum 600m ? Have you already hiked with your backpack for 5 or 6 days in a row ? Answering these questions will allow you to evaluate your capacities and plan an adapted training to prepare for your trek.
