I haven't run or exercised for two weeks. I feel sick all over. No wonder I have a little cold. It has basically recovered today, and when the altitude of Nyingchi has dropped to more than 2,000, it is time to go for a run. It snowed heavily when I left Nyingchi and passed the Sejila Pass, so suddenly. The Mira Mountain Pass is so spectacular, with an altitude of more than 5,000, as if to a lonely alien planet.
