Not only in high-performance sports but also in competition-oriented recreational sports, mental skills are increasingly becoming the decisive factor between victory and defeat. Factors such as self-attitude and attitude towards competition, fear of failure, efficient handling of disappointments, successfully coping with critical situations that arise during competition, and avoiding loss of concentration at crucial moments play a significant role. Loss of self-esteem and motivational issues negatively impact the training process. Those who want to influence their readiness to perform in training and their performance in competition must possess the necessary mental tools to achieve their personal goals. This book focuses specifically on long-distance running (from the 5,000-meter race to the ultramarathon).
