It feels like a long haul. Your legs notice the kilometres far more than any height, because the route is almost completely flat. Your mind has to cope with repetition: path, field, horizon, another stretch of path.
You soon leave Salamanca and its golden sandstone behind you. After that, it becomes quiet and open. It’s the first day, so your rucksack is still new to your shoulders and your feet don’t yet know what’s in store. Start gently, because almost 9 hours takes patience. Robliza de Cojos is a small village. No bustle, but you’ll have the satisfaction of a first stage done.
Stretch your calves this evening and be proud of yourself.
