Fouling in the triple jump stings extra, because the board sits much farther from the pit than in the long jump, and a scratched jump is a lot of effort for a red flag. Fouls almost always come from a run-up that does not deliver you to the board the same way every time, not from misjudging the board in the moment. Here is why you scratch and how to keep your jumps legal.
If your approach varies, sometimes you hit the board and sometimes you sail over it. The fix is the same as in the long jump: a measured, marked start, the same building speed every time, and a stride pattern you trust. You cannot aim at the board jump to jump. You run the same run-up every time so it comes up where it should.
Triple jumpers who try to squeeze extra distance creep their start forward or push hard at the end and end up over the board. The board is a fixed point. Earn distance with a fast, balanced run and clean phases, not by stealing inches at the line.
Because the approach is long and the event is taxing, tired legs change your stride and push your takeoff over the board late in a competition. Conditioning the full run-up, and keeping your start honest when you are tired, keeps late-round jumps legal.
A foul is a run-up story that ends at the board. Film your approach and takeoff from the side, the AI shows where your foot lands relative to the line across several jumps and how much your run-up is drifting, so you can fix the start instead of guessing at the board.

A foot landing behind the foul line counts. A toe over the front edge is a scratch, even on a huge jump. Consistency in the run-up is what keeps the foot behind the line.
