Answer 1

For a long-distance runner, the most important component would be **cardio-respiratory endurance**. This is the ability of the heart, lungs, and muscles to work together efficiently during prolonged physical activity. While muscular strength, reaction time, and agility may have some role in overall athletic performance, cardio-respiratory endurance is crucial for sustaining the energy and stamina required over long distances.
