Day 3: Tres Equis to Atirro (Casa Bambú), Stages 5, 6, and part of 7. 18.9 trail miles plus two bonus miles (21 miles) 3,251 feet gain, 3,505 feet descent (plus more of both with the bonus miles). The first 10 miles of the day were all uphill. At first, gentle, and then we were really climbing all the way up to 4,000 feet. Crazy to think we were just at sea level two days ago! The sunrise was beautiful coming over the mountains. We had quite a bit of road walking on pavement
