Javelin Throw – Runway
The minimum length of the runway shall be 30m (98 ft.-5 in.). The maximum length of the runway is 36.5m (119 ft.-9 in.). It shall be marked by two parallel white lines 5cm wide and 4m apart (lines are not a part of the 4m measurement, therefore the full width of the runway shall be a minimum of 4.3m, or 14 ft.). The throw shall be made from behind an arc of a circle drawn with a radius of 8m. The arc shall consist of a strip painted or made of wood, metal 7cm wide. The arc shall be painted white and be flush with the ground. Lines shall be drawn from the extremities of the arc at right angles to the parallel lines marking the runway. These lines shall be white, 75cm long and 7cm wide. The maximum lateral inclination of the runway shall be 1:100 and 1:1000 downward in the throwing direction.
For new construction, the minimum runway length shall be 33.5m (109 ft.-11 in.) and the maximum length shall be 36.5m (119 ft.-9 in.). The runway is recommended to be equipped with an artificial surface for its entire length. When artificial surface is used, the surface should extend 1m past the foul line for safety.
Same as NCAA, but with no comment regarding artificial surfacing. Lateral inclination is no greater than 2:100 and not more than 1:1000 from the throwing area to the landing area. No minimum runway length.
