Stage 25 Huanco to Cerro de Pasco This stage was a big day in terms of climbing. The whole cycle was an ascent from under 2000 m to 4400 m. I think the combination of high altitude, and cold worked on all of us. I managed to come in second in the group.. I was fairly incoherent and chilled to the bone. I went to bed and was out for a couple of hours.
