Track events are distinguished based on their distance, categorized into sprints, middle-distance, and long-distance races. Sprints include events like the 100m and 200m, focusing on speed and explosiveness. Middle-distance events, such as the 800m and 1500m, require a combination of speed and endurance. Long-distance events, including the 5000m and 10,000m, emphasize stamina and pacing over a more extended duration. This classification ensures that athletes compete against others with similar physical and technical capabilities, showcasing their unique skills.
