Throw the javelin, and observe the javelin as it travels. Ensure the javelin is thrown from behind the designated line. Remain stationary until the javelin has landed in the ground.
Ensure the field is free from any potential dangers such as other javelin throwers. Get another individual to stand at the center of the throwing line with the start of the measuring tape. Ensure the measuring tape is resting on the ground. All measurements should be taken from the same point to ensure accurate results.
Approach the javelin once it has landed. Remove the javelin from the ground and place the measuring tape over the dent in the ground created by the javelin. The javelin must have landed tip first for the distance to be counted.
Take the measurement from the throwing line to the nearest point created by the dent in the ground.
