A few thoughts from me, inspired by the blog linked in the original post:
1. Knowing why you are going is good, but also recognize that you may be mistaken. People sometimes discover on the Camino that the "why" they thought they left with wasn't the "why" that they discovered on the Camino. The other side of knowing why you are going is the often cited top tip to "go without expectations" or "let go of your expectations". For some, it is best not to undertake a Camino in pursuit of something in particular but rather in a state of openness for what your Camino will have to offer.
3. Preparing physically is good. You talk about preparing to walk under load. David (above) talks about preparing for the ascents and descents. One of the toughest things about the Camino, and the hardest to prepare for, is that it is a day after day after day effort, unlike the physical preparation we tend to do. When I walked in 2016, I did no preparation and really felt it. I did better before my 2018 Camino, walking regularly with my loaded backpack, often where there were hills. But as it got closer to my departure day I would sometimes walk the long distances a couple of days in a row (weekends). When I could do the distance with loaded backpack three days in a row (long weekend) without too much exhaustion, I knew I was physically prepared.
4. I totally agree with doing the research. I know that some people like to just show up and walk liking the discovery and surprises. I like knowing my options and, no matter how much research I do, I still find that there are discoveries and surprises to be had. But I think there is a difference between research and decision-making. And some of the questions that are posed in this tip (where will I be staying? How far will I be walking each day?) come across as decisions to be made. And, as I see it, no matter how much research you do, those decisions are best made on the day. You want those decisions to be as informed as possible, and research will only go so far in informing those decisions. Other critical factors could be: What's the weather like? What's my physical condition? Who am I walking with, what are their preferences, how important are their preferences to me? So do all the research. Make plans even. But hold those plans in an open hand, ready to have them fly away and change as you get additional information during your Camino.
5. The first word I like to learn in any language is "thank you" (
gracias is Spanish). If your Camino will take you to France it is
merci. If it will take you to Portugal,
obrigado (
obrigada if you are a woman). If you are walking the Camino Portugues, note that Portuguese is a separate language from Spanish. They are related and, in theory, Spanish is intelligible to Portuguese speakers (although not visa versa). But if you are walking the CP, best to learn some Portuguese, too. Where that is not sufficient, I would advise trying your English before trying Spanish. From what I have read and heard, that is preferred by the Portuguese people in general.
6. For those walking the
Camino Frances (or the Camino Aragones), I would highly recommend
The Pilgrimage Road to Santiago: The Complete Cultural Handbook by David M. Gitlitz and Linda Kay Davidson in pursuing this tip. It is also available in a Kindle version for those wishing to take it with them without adding to the weight of their backpack.
7. What we choose to carry in our backpacks and how it affects our Caminos is one of the great lessons that the Camino has to offer. I understand and acknowledge the many reasons to use the backpacking forwarding services and pass no judgement on those who use them from necessity or personal choice. But doing so does, to a certain extent, diminish the opportunity to learn these lessons. One phrase I heard on a Camino podcast was "We carry our fears" and this really struck true to me. One thing that was always loading my backpack in 2016 and didn't always get used was food supplies. I called it "insurance". At root, I was afraid of walking with a hangry teenager.
It might be an interesting exercise to look at each thing you are carrying and think about what it represents in terms of something you are afraid of.
8. In addition to your walking shoes, many people often bring lighter footwear (flip-flops, crocs, or the like) to wear in the evening after the day's walk is done. My choice was to bring hiking sandals. Early on in my 2016 Camino, when I had a rash on my feet, it was nice to be able to switch and walk in them for the day. I've also heard of others who, for blister reasons, switched to their hiking sandals from their shoes or boots and found it very helpful. Bringing hiking sandals instead of crocs or flip-flops may be a bit more weight, but I find the additional flexibility well worth it.
10+ Engaging with others should really be much higher on the list.
