I walked three different Caminos during my trip this year. I started with the Madrid which was new to me, re-did part of the Frances where I had some unfinished business and then ended with the Portuguese from Tui.
In my case I enjoyed the Madrid the most because of my many kind interactions with local Spanish people and because of the challenges of the Madrid. I especially liked the challenges represented by the solitary nature of the Madrid.
Next, I enjoyed chasing away the ghosts of my 2019
Camino Frances where I became seriously ill after Sahagún and as a result struggled from there to O Cebrerio where I collapsed and was taken to hospital.
Much of that portion of the Frances was a blur in my memory and I enjoyed seeing it again with fresher eyes. I also marvelled at my stubbornness in 2019 to keep putting one foot in front of the other and keep going and contrasted that with my fitness at the same points this year when in three days I easily walked the same distance that had taken me seven days of struggle in 2019.
After these two experiences, walking the Portuguese became somewhat mechanical and while parts of it were nice, overall I was underwhelmed.
I suspect that many people will jump in on this last paragraph and extoll the virtues of the Portuguese and I am certainly not arguing with them on that but rather I am saying that in my case this series of Caminos had the Portuguese not be particularly interesting or significant for me.
From this I would offer you two pieces of advice.
Firstly when you rewalk the Frances don't try to relive the best parts of your previous pilgrimage. Throw those expectations away and try to walk it anew.
On every occasion when I purposely revisited a place where I had had a great experience in 2019 I was disappointed this year. On the other hand I had some of my most memorable days in places that simply didn't even register last time around.
Second piece of advice, perhaps walk the Portuguese first so that you are forced to treat it as a completely new experience then tackle the Frances with your fresh eyes. Perhaps consider starting at a different point to really reinforce that this
Camino Frances will be completely different from your last one.
Of course, what you eventually choose to do will be the perfect choice for you and neither I nor anyone else can make those choices for you.
Buen Camino!
