Formally quite simple: Go North for 470 km. But: 150 km are gravel pistes with potholes of all sizes and depths, means six hours for that part alone. Several passes above 4.000m, highest point of the day was 4.630m. There, even a simple photo stop becomes an exercise that can make you dizzy. Gave a shepherd a lift to save maybe an hour of walking. She probably never before had traveled in a modern car, let alone used a safety belt... Later, I met a guy who had cycled his way up there from Chengdu which is around 700km away. Did I mention that we caught some dust?
