A standard track and field race varies in length, with many common distances including 100 meters, 200 meters, and 400 meters, but races can also extend to longer distances such as 800 meters and up to the marathon distance of 42.195 kilometers. Event durations depend on the specific race type and individual athlete capabilities. The focus on speed and endurance varies across events, with sprinters typically emphasizing explosive bursts of speed while distance runners train for stamina and pacing over longer distances.
