Nutrition is one of the most important part of an successful expedition. On a winter expedition in arctic climate you will burn over 5000 calories a day.
It’s 4 weeks ago now I got back from my solo crossing over Lake Baikal.
-The deepest and oldest freshwater lake in the world. I walked 692 km over the frozen lake in 14,5 days. The last 6 days I walked between 50-60 km a day for 12-13 hours without any breaks more than a short stop to drink water every second hour. Eating was done by walking to save time.
I had temperatures down to minus 35 during the day at the start of my expedition, it was a very tough and cold start. In these temperatures you can only take food that doesn’t freeze when it gets really cold, you also want food that is as light as possible as you have to carry all your food with you. I had food for 17 days with me.
It’s all about routines on a winter expedition. My alarm was set on 4am every day, at 6-6:30 am I started to walk. The time between there I got out of my sleeping bag, turned my kitchen on to get a little bit of heat in the tent and melt water to top up my thermos. I ate breakfast, drunk a lot of water and started to pack my sled and tent.
My routines during the day was pretty simple, I walked for about 12 -13 hours and had one stop every second hour to have a little drink and grab something that I could eat while I was walking. Sometimes I stopped for a photo or two.
Before it got dark in the evening around 6:30-7pm I stopped for the day to set my tent up. It usually took me couple of hours to set the tent up, get everything organized, melt water and cook dinner. Around 11pm I tried to sleep. I only got about 2-4 hours of sleep most of the nights due to very loud noise from the ice that was cracking all the time.
