A long long day owing to sore muscles and fatigue from the last couple days. But a beautiful real through woods and farmland at dawn, passing through Burguete, one of Hemingway's favorite towns.
Lessons learned from from the long hot walk into Zubiri in the afternoon:
take shoes and socks off at least once during the walk; use every font to refill water bottles; lots of snacks especially when you start to zone out during the last five km.
