What is the standard width required for all painted lines on a running track________________________?
Show answer Hide answer
Answer: B. 5 cm
Explanation
The standard width required for all painted lines on a running track is 5 cm. Precise line thickness ensures runners can easily distinguish lane boundaries and starting marks. Track marking regulations mandate uniform five-centimeter widths for fairness and accuracy. White or contrasting paint is applied using specialized striping machines on synthetic track surfaces. Lane lines are measured from the outer edge of the line in accordance with official rulebooks. Maintaining visible lines is essential for judges to detect lane infringement fouls during races.
Groundskeeper crews repaint track lines regularly to prevent fading from weather exposure and heavy use. Athletes running the curves must stay within their assigned lanes marked by these precise boundaries. Television broadcasts rely on clear track markings to help viewers understand race positioning. Seven centimeters is too wide and violates the strict international line-marking specifications. Six centimeters exceeds the standardized five-centimeter measurement used in professional stadiums. Four centimeters is slightly too narrow and fails to meet official track federation guidelines.
