This compact volume answers 150 specific questions from the daily life of ultrarunners, primarily targeting all ambitious athletes who have already gained some experience in this field or possess basic knowledge. The author deliberately omits these basics and focuses on practical aspects that concern ultrarunners: from general keywords such as suitability for ultrarunning to training components and plans, competition techniques, psychological aspects, as well as supplementary measures for ultrarunning and annual planning for competitions. Norbert Madry takes into account all aspects that this fascinating sport entails in running practice. Designed as subjective advice from a running partner, he shares his personal treasure of experience from thirty years of ultrarunning - a book that motivates and is certainly of interest to some.
