You learn very quick whether or not the altitude is going to affect you. Unfortunately, i did not have the chance to stay a few days in cusco before hand.
That probably would have helped tremendously. Within minutes of starting our first day i found myself gasping for air. In no way do i think of myself as super fit, but i am also not a couch potato, and i was seriously taken aback by how often i need to stop to take a breath. Day two was even worse in this sense, but i was definitely a trooper. ;).
I have to say it was absolutely worth the pain. This place is absolutely breath taking; however, if it were not for Juan Carlos i don't think it would have been the same.
Even breathing heavy he managed to bring a smile out in me. I will be recommending this trekking service to anyone i know entering the country. Muchos gracias!!!. Hope to see you all again! Take care!
