Why does my triple jumper's landing come up short even when it looks fine?
A triple jump mark is measured from where the body touches sand closest to the board, and a clean-looking landing can still cost you that distance.
The hop looks flat. The step holds its rhythm. The jump phase has real lift. And then the mark comes up a foot shorter than the approach speed said it should. Nothing in the three phases looked wrong, so the instinct is to go back and re-check the board, the steps, the speed. Often none of that is where the distance actually went.
Where the measurement actually gets taken
A triple jump mark, like a long jump mark, is read from the board to the nearest point of contact in the sand, not from the board to wherever the athlete ends up standing. If the legs are still cycling underneath the body at touchdown instead of reaching forward, the heel lands closer to the hips than it needed to. If the athlete lands and immediately falls backward, or sits down hard in the sand, the recorded mark drags back toward the body on the same landing that just happened. Both cost real centimetres, and neither one is a phase problem.
The two causes worth checking first
- Legs not extended forward at the instant of contact, because the jump phase was rushed and there was no time left to reach before the feet hit sand.
- A backward fall or sit-down immediately after landing, which moves the nearest point of contact back toward the body after the fact.
What usually fixes it
Standing long jump finishes, where the only job is shooting the heels forward and holding the landing rather than falling through it, transfer directly. So do short-approach jump-phase reps that isolate just the last phase, so the athlete can feel the difference between reaching and simply arriving.
What the Film Room measures here, and what it doesn't
The triple jump setting reads the hop, step and jump from the hip trace on the runway: first takeoff angle, how many phases it can find, hip rise per phase, overstride between steps. All of that is the approach and the three phases themselves.
The landing in the pit is not one of the numbers it reports, and a camera framed to catch the runway and the board often does not even have the sand in frame. What happens at that last touchdown, legs reaching or legs still cycling, body holding or body falling back, stays something a coach has to watch for directly. No measurement from a side-on clip of the approach will tell you.

Why does my long jumper land and then fall backward in the pit?
A hard landing that pitches an athlete back onto their heels usually loses more distance than a slightly worse takeoff ever will.
Read →Why does my long jumper land shorter than their speed says they should?
A fast approach and a short landing usually means the speed never converted at the board, not that the athlete stopped being fast.
Read →Why is my triple jumper fast on the runway but short in the pit?
A fast approach that does not turn into distance almost always means the speed is being spent going up instead of out.
