I take most of my rest days at destinations. The length of the riding period is dependent on how long it takes to reach the next interesting place to explore. I try to aim for a six-one average, but nothing is set in stone. Once during a rain day I just did't feel like cycling and ended up chilling around my tent for a day. Local villagers gave me some rice, eggs, and bean curd. I cooked those up, ate, wrote in my journal, slept, etc. It was great.
