This graphic really puts things into perspective. See the very solid, popular race, the Boston Marathon, down in the bottom left? Now look at the “race across the sky”, The Leadville 100. Many have accomplished this race too, but when you’re in the midst of training for it, all you can think about is the intimidation of the altitude and the long inclines that seem to endure the entire 100 miles. David Goggins says “The most difficult part of training is training your mind. You build calluses on your feet to endure the road. You build calluses on your mind to endure the pain.” In that moment of wanting to quit, Hans recites his own personal mantra, “just f*cking do it, damn it!” Come August 18th, there is no doubt that he will.
