A few years ago, I went to Nepal. I met a group of British people and trekked with them through a remote valley to climb a 21,000' peak.
We walked for days, up and down hills and over 15,000' passes. We hiked 6-10 hours a day, and there was an attractive simplicity to it. All we had to do was walk. We ate whatever the Sherpas cooked for us. We drank water constantly, because hydration helps you acclimatize to high elevations. I ate whatever I wanted and still lost weight; everyone did. As I walked I realized that this is what our bodies want: long walks, simple food, and lots of water.
Sometimes I need a reset. Especially in winter, the routine of gym/running/exercise bike/elliptical gets boring and I dread it. When this happens, I go for a walk in the woods instead.
I'm fortunate to live close to a system of trails that is only open to non-motorized activity. As light snow fell, I walked through the gate into the forest.
There is a network of trails through here. I usually run on them.
Nobody had been on this one since it snowed.
There are a lot of intersections, lots of choices on where to go.
The clouds were low over the mountains across the farmers' fields.
Tomorrow I'll get back to more strenuous exercise. But today, an hour and a half in the snowy woods was perfect.
