The Traditional Inca Trail has a moderate level of difficulty; we walk 39.4 kilometers, first 2 days to up the mountains until 4200 masl (Warmiwañusqa pass) and 2 days to downhill.
We advise make physical exercise like walk, run, go to the gym, or similar unless a month before to begin your trek.
We advise stay in Cusco city (3300 masl) by 2 days or more for your body acclimatize to the altitude, and drink a lot of coca tea (make with coca leaves, it is legal in Peru).
