The word of the day: adjustment.
I spent the better part of my first day adjusting. Adjusting the straps on my backpack so it fit just right. Adjusting the laces to my hiking boots so they stopped coming untied. Adjusting to walking downhill with a 20 pound rucksack on my back. And mostly, adjusting to hearing nothing but the sound of my own labored breathing.
After a few hours and 24 kilometers later… I finally made it to Puente de la Reina. And I immediately took a nap fit for a Queen. :)
Tomorrow, Puente de la Reina to Estella–about 21.5km. I hope to get an early start!
