Usually I exchange one of the following greetings: ola!, buenos dias, que tal, buen Camino. And, usually, unless they have ear plugs on, it is reciprocated.
I also look at how their bodies are responding to the rigors of the El Camino de Santiago pilgrimage.
What I'm seeing is a growing number of noticeable limps. Each limp is different.
The limp may come from sore muscles. Or, from blisters. Or knee problems. Or calf issues. Or something else.
The first thing to hit me about this is that our bodies can only take so much.
The second thing that hits me is that most continue to walk the El Camino even with their limp.
Sure some do quit. Some take break days to try to recover. My guess is that most don't. Most continue on the trek even though their body is hurting.
So far I have been lucky. Let's keep our fingers crossed. I have soreness -- in the knees, a little bit in the calf, definitely in the feet, and clearly on my bottom. But, as far as I know, I am not limping yet.
