Long-distance running is a form of endurance running that typically involves races longer than 5 kilometers. Common distances include the 10K, half marathon (21.1 kilometers), and the full marathon (42.2 kilometers). This sport requires physical stamina, mental resilience, and proper training to build endurance over time. Runners often follow specific training plans that include long runs, speed work, and rest days to improve their performance. Nutrition and hydration are also crucial, as they help maintain energy levels during long runs. Many long-distance runners participate in organized events, fostering a sense of community and competition.
