Just finished the second day at Machu Picchu by hiking up to the top of a mountain. What better way to ensure that every last bit of energy was drained from my body. The rest of the trip is easy. We take the train back today at four o´clock to Cusco, do some shopping and then it is off to Lima for the flight home. That means I will need to re-focus on other things like work and side-projects. Oh ... and the holidays.
