I get it you only have 20 days, what is important to you? To arrive in Santiago?
The pilgrimage ? The walked way ? Sight seeing? The first one I wanted to see Santiago and had only 3 weeks, I chose the easiest for me. Was plenty challenging but I counted Rest Days in after 2 weeks I was so fit that I continued to Muxia. If you are fit and healthy 20 km a day is doable, last year I walked only 10 inbetween but ended up walking an additional 10 detours and sightseeing. I was able to see so much more. What is your greatest challenge?
I am a planner , I guess it’s a national past-time to have plan a, plan b and c and a contingency plan, so I organised the flight there and back, starting point would be good to know and only planned one day at the time. It was so refreshing and relaxing and it is really easy.
It’s fun to plan and in you mind to walk it all.
But if you prepare your feet, have good walking shoes a decent backpack, your friends may be able to lent you one.
Last time I learned every decision I made was the right one, at the time I made it it was the best I could do, on the Camino and in my life.
Without these decisions I would not be where I am. So never fear…
That’s the truly great thing about the Camino for me. This freedom and the experience the Camino will provide what you need,, maybe not what you want but truly what you need.
Here my five cents worth….
