After a long time, I went back for a medium/difficult level hiking. It had been almost 3 months since I had hiked that hard. First, I hurt my foot, then my back. Because of that I was only doing a nice, easy walking. Yesterday I was ready for a difficult hiking. At first was very hard. At some point, I had to stop, and rest. I was feeling so bad that I was even nauseating. After resting, I did very well. It was really good to be on top of the mountain, and see the beauty of nature.
