You crossed the icy wastes of Greenland with a notebook. What did you write?
Firstly, practical, fairly technical things. What was the weather like, where was the wind blowing from? Have I taken my medicines? Is the equipment in order? Is the tent OK? I recorded facts and to-dos every day.
How important were these notes?
They help keep your head clear. Which is a psychological effect that is not to be sniffed at on an expedition. I often had doubts early on. What if I’ve miscalculated on my food rations? What if the weather suddenly turns? In situations like that, writing things down helped me feel safe. I like to compare it with the “Pensieve” in Harry Potter: a stone basin where thoughts and memories are stored for referring back to later. My “Pensieve” is my notebook.
Were there moments that scared you?
You can prepare and train as well as you like, plan your route, organise your equipment, take precautions for weather changes – but in the end, you’re on your own, standing on your skis in an ice desert, experiencing everything for the first time. There are things you can’t simulate in training. I knew that after two or three weeks on an expedition like this, hunger almost doubles. How will your own body react? That uncertainty is scary.
How did you deal with this fear?
I wrote it down – but always combining it with something that gave me courage. I developed a system for this after a few days. Every day, I made a note of my three greatest fears, and right next to that, three things I was most looking forward to when I got back. Often quite banal things: strawberries, pizza and asparagus, for example. So my daily notes got longer and longer.
When do you have time to write on an expedition like this?
The days are jam-packed, there’s not much spare time. I set my alarm a bit early and spent about 20 minutes writing immediately on waking up every morning, still lying in my sleeping bag. Always applying the same principle: first the facts and technical things, then a section on what we’d experienced as a group, and finally the passages about my own feelings.
