I think I've said this on a previous expedition, but out here I'm acutely conscious of my own heat, and of having to shepherd and protect it against nature. I often think of us as two tiny pinpricks of thermal red in a giant expanse of deep-cold blue, inching our way across its surface. The feeling of self-reliance and self-sufficiency is strangely satisfying, yet of course compared to Scott, Shackleton, Amundsen et al, we're soft.
What an amazing feat! It is great to follow along, day-by-day, from the comfort of my in-home pub's fireplace. Sorry Ben.
