We had a beautiful and varied 5 hour trek today. The walk was entirely on a trail. This is our definite preference, but it does mean that the walking is more challenging. There were several steep climbs on well constructed stone stairways that had our legs burning. The walking times do not adequately reflect the effort expended on some legs, as the climbs take a physical toll. Many of the other trekkers have porters, which would make things much easier. The porters carry up to 30 kilograms, which means they are often bearing two backpacks lashed together.
