Is it different on the Camino? Will I get the motivation from others to continue and move on. I don't want to be a pre-quitter LOL but, I am afraid of getting there and not being able to walk the distance needed daily. I am 53 and in relatively good health. I imagine that walking on the Camino and not worrying about having to be somewhere or do something will make it easier, and also having company at times. Do most people think about not being able to walk the distance? any advice or suggestions will be greatly appreciated.
I am the same age that you are, and I was fortunate enough to receive my first camino as a birthday gift when I was 46; I found the time to go just prior to my 47th birthday.
Thing is, I really wanted the adventure, but I really used to hate walking. Prior to my first Camino (3 under my belt now), I found the activity tedious, and I preferred to do almost anything else. ...and I am a non-driver, so it was not about cars. I simply preferred to bike, or ride transit.... didn't matter as long as I did not feel myself to be plodding along with my mind going in circles.
In preparation for the Camino I went away from home for 6 weeks and walked outside of urban areas. I got up to distances of about 24 km max, and not every day. I did enjoy it more out of the city though.
And so there I was, still an ambivalent walker, and totally worried about doing the kids of distances we might feel the pressure to so on a "once in a lifetime trip" that gives us only 42 days to get there and back and cross a country. In essence, 6 days are lost to travel, 3 at each end. So we have 36 days... some rest in there, or some slower days.... but there may be a real pressure felt unless one develops a certain comfort with not being a purist about pilgrimage from a given point to a given end.
Many of us find over time that those points are negotiable -- for whatever reason(s).
Here's the thing: maybe it's only your first camino that you are planning, even though it feels like your only one possible. I never dreamed I would do more than one, but I am already planning #4 (with my Spouse in 2022) and #5 (with my step-sister in 2023).... and #6 (on the Norte before I turn 60 in 2027)...
And so I think that the other answer to your question, implicit above, is that yes... we worry about distance... and then find that yes, other encourage us along, the road encourages us along, the sites and the adventure and the difference encourages us along....
And now, I could never say anymore that I dislike walking. Walking is my solace, my companion, my refuge, and my energization....
I wish the same for you....
And if you find that it is not, then leave the camino, and spend several days in each city along the way. It will be as fine a trip as any you might take.
