King stage. I directly start climbing in a single steep and long climb to 4.800 meters. I feel strong until around 4.000 but then the altitude takes over and I feel very weak. My speed drops to 6kmh on the last two km. After the pass the road stays above 4.400 meters for another 100 km. It’s a beautiful mountain and desert landscape but I feel extremely weak. In the evening I descent to the border at 4.200 meters and find a small village on the Argentinian side. I start feeling better again at this elevation.
