Long-distance runners face unique challenges primarily related to endurance and mental resilience. Prolonged exposure to physical strain can lead to fatigue and overuse injuries, requiring careful management of training loads. Additionally, the psychological demands are significant, as maintaining focus and motivation over long distances is crucial. Weather conditions can also impact performance, with factors like temperature and humidity affecting hydration and energy levels. Nutrition becomes essential to sustain energy reserves, and strategizing pace is vital to avoid depletion.
