Well...much as I'd like to sit here and write about how I conquered Peru's Inca Trail, alas it would be untrue. After 3 and a half days of acclimatizing in Cusco and feeling completely fine at altitude, on the last afternoon before the start of the trek I got some bad altitude sickness out of the blue. Then followed that up with a stomach bug. Had tried to do everything right to prepare and stay healthy, and my wife remained completely fine, but them's the breaks. Long story short, no trek and wound up back home a week early.
At least it all happened just before we got out on the trail and not during. Would have been very difficult to deal with 2 days into the mountains or whatever. So a bit of a shame, but must still say that Peru is a beautiful country full of lovely people. Perhaps we will get back one day. Home safe and well is the main thing for now.
