Camino Day 7 How long until the next shire?

On days 7 we traveled on from Navarette to Najera.  Our walking days follow a pattern and feel pretty similar. We get up (as early as we can stand - sometimes 5a, sometimes as late as 7a) and get ready. It seems to take us at least an hour for all of us to be ready to head out. This includes getting dressed, repacking packs with bedding and clothes, foot care, breakfast, and refilling water bottles.

We walk for about 2 hours then stop for a snack. We eat like hobbits on this walk - breakfast, second breakfast, elevenses, lunch, afternoon tea/coffee, dinner.

We then walk another 2 hours then stop. Then another 1-2 hours, then done. Leaving early and cooler temps affects our progress greatly! If we leave by 6:30, we can be 20+k down the road by 1-2pm and take a long afternoon rest (siesta). Can this become a thing in the US? Naps are the best!
In Najera, we mailed a package on to Santiago for 11 Euro, so MK and I have lightened our packs by a few pounds each. I sent ahead a pair of pants, a pair of leggings, a pair of socks, and a deck of cards.

At the bar where we had dinner, these two guys were belting out Spanish tunes. They handed Dad a guitar, and sang as Dad played for a good 20 minutes. Dad’s Spanish song repertoire is not that large, and they kept asking for songs Dad didn't know, but he extemporized really well. People from around the bar got up to dance and sing. We had a great time!
