Getting to the Next Cash Ad on a Single Day Ultra Marathon?

In the arctic or siberia, it's more about just breaking down five kilometers at a time. I i get to a point in my mind where i know what i need to do, because i've limited food supplies in my sled. You know, i'll bring 20 days plus five emergency if something bad goes wrong. And a soo focus on that expedition, go as far as we possibly could every day. In some days, a full effort the entire day, going back and forth with the sleds. It would take, we cover an kilometers in a day is ridiculous. So all you're thinking is, get over ten t you know?
