“Could you survive the night with what you have in your pack?” My friends roll their eyes at me, but I am dead serious. I want you to imagine with me for a moment. It’s a perfect fall day. The sky is bright blue, the sun is shining and it’s a comfortable 65 degrees. You have had a great summer of training and you are feeling strong and excited for this 20-mile mountain adventure with your two closest running friends. The day is going great until 15 miles in and suddenly a rock shifts under your weight and you go down HARD! You can tell immediately that your lower leg is broken and you won’t be able to put any weight on it. Falling and getting hurt is not always avoidable, but how you prepare for this situation is what will make or break your experience.
