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 for long distance runners, as they need to fuel their bodies adequately to sustain energy levels during extended periods of running.
