If your javelin keeps drifting left and landing off the line or out of the sector, you are losing distance and legal throws to a direction problem. For a right-handed thrower, a javelin that goes left usually means your run-up or your block is pulling you across your body, so the throw is sent off to the side instead of straight down the line. It is a fixable footwork issue. Here is what is happening and how to throw straight.
The front block leg should land roughly in line with your run-up, straight ahead. If it crosses over to the left of your line, it swings your hips and the throw to the left with it. Plant the block foot straight down the line, not across it, and the throw follows.
Slinging the javelin around the side, with the elbow low and the arm pulling across your chest, sends it left and flattens it. Throwing over the top, with a high elbow pulling straight through the point and down the line, keeps the direction true and is safer for your elbow.
If your approach curves or your crossovers carry you off your intended line, you arrive at the block already aimed left. The run-up and crossovers should track straight down the runway toward the throw. A drifting approach aims the whole throw before your arm ever moves.
Direction is set by your run-up line and your block, both visible on video. Film from behind or the side, the AI shows whether your block leg lands across your line and whether you are pulling across instead of over the top, so you can fix the cause instead of aiming right to compensate.
