fantastic to know someone who did it all the way from Poland. Maybe this idea or temptation will have to wait for my retirement, but who knows?
My estimate is based on a few mountains trails I've completed. Ex, I've done Główny Szlak Beskidzki averaging just below 30km per day.

I encourage going to Santiago a lot - amazing experience.
Through the way, 30km/day is a standard, however at the end (after few months of walking, and with proper infrastructure), it can be easily 30+. I was "racing" with one guy in his 50s or 60s, who was doing the 30+ daily for a long time (went from Netherlands), so definitely it is doable.
well, my top is 50km in one day, the whole length of the Pieniny Mts, with +2000m of total elevation. 16hrs elapsed. Possible occasionally, but not back to back
