How is the lane width for athletes in races up to 400 meters determined on a synthetic track?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Each lane is 1.22 to 1.25 meters wide, marked by 5 cm lines.
According to the World Athletics (formerly IAAF) standards, the standard width for a running lane on a synthetic track is precisely 1.22 meters (± 0.01 m), though some tracks allow up to 1.25 meters. All lanes are separated by white lines that are exactly 5 cm (50 mm) wide. T
his specific width ensures that athletes have enough space to run safely without colliding, while maintaining the standardized 400-meter lap distance. The measurement of the lane includes the width of the outer line but excludes the inner line of the running path.
