Javelin Throw Rules
A running-approach throw of a pointed spear-like implement, for maximum distance.
Each athlete gets a fixed number of attempts (usually 3-6) down a runway; the best valid throw counts.
- •Longest valid throw, measured from the throw arc to where the tip first lands, wins
- •Distances measured to the nearest centimetre
- •League standings can rank by best distance across the season
- •The javelin's metal tip must strike the ground first for the throw to be valid
- •The thrower must stay behind the throw line/arc — crossing it is a foul
- •The javelin must land within a marked sector for the throw to count
Legal throws and the landing rule
The javelin must be held by the grip and thrown over the shoulder or upper arm; slinging or hurling it is not permitted. The athlete must not turn their back to the throwing area at any point during the approach and delivery.
For a valid throw, the tip must strike the ground before any other part of the javelin. It does not need to stick in, which is a common misconception, but a flat landing where the tail lands first is a foul.
Run-up, safety and implement weights
The run-up is longer than in any other throw, typically 30m or more, ending at a curved throwing arc that the athlete must not cross. Withdrawal of the javelin during the run-up and a strong block with the front leg are the technical keys.
Javelin is the throw with the widest safety perimeter. Never allow retrieval while another athlete is throwing, and always carry javelins vertically. The senior weights are 800g for men and 600g for women, with lighter implements for other categories.
Common questions
Does the javelin have to stick in the ground?
No. It only needs the metal head to touch the ground before any other part of the implement. A throw that lands tip-first and bounces flat is perfectly valid.
What are the standard weights?
800g for senior men and 600g for senior women, with lighter implements for junior and masters categories. Using the wrong implement invalidates the entire competition, so check before the first throw.
How is the throw measured?
From the point where the head first struck the ground to the inside edge of the throwing arc, measured along a line to the centre of the arc's circle. The throw must land within the marked sector.
What are the main safety rules?
Never retrieve while anyone is throwing, always carry javelins vertically with the tip down, and keep a wide sector clear. Javelin needs more space and more discipline than any other event on a club programme.
