Why does my high jumper clear more at home than at away meets?
The runway is not the same everywhere. A jumper who has only ever felt their steps on one surface finds that out at the worst possible meet.
A high jumper clears every height in practice and most heights at home meets, then goes to an away meet and misses heights they clear routinely. The approach looks the same on video. The surface under it usually is not.
The apron is not a constant
Some schools' high jump aprons are a thin rubber mat laid over concrete. Others are the same all-weather surface as the track. A few are still grass. A curve that is marked and measured one way at home can be a different radius or a different length at an unfamiliar venue, and a jumper's check marks were set against the home surface, not the away one.
- A firmer or softer surface under the plant foot changes how much the ground gives back on takeoff, so the same approach speed can produce a different takeoff feel.
- A shorter apron than the one at home forces a jumper to compress their marks mid-approach, which is the worst moment to be thinking about anything other than the next step.
- A different backdrop and light at an unfamiliar venue change how the bar reads against the sky, a small thing that matters for an athlete relying on peripheral cues to judge the plant.
- A curve with a different radius changes how early the athlete has to lean into the five-step curve, even when the number of steps stays the same.
What actually helps
Arrive early enough to walk and then run the approach on the actual away surface before the competition starts, rather than trusting a check mark copied straight from home without testing it. A few run-throughs without a bar is cheap insurance against a surface nobody has felt before.
What the Film Room adds
Film the away warm-up approach with the high jump setting and set the hip rise and takeoff angle against the athlete's usual home numbers. If both numbers drop even though the steps look clean, the surface is very likely absorbing speed the athlete is not actually losing. If the steps themselves look ragged, the problem is the unfamiliar venue in the athlete's head, not the ground under their feet.
A single 2D camera standing at an away meet can tell you the numbers came in lower than at home. It cannot tell you how much of that gap is the runway and how much is a jumper who has never had to deal with an unfamiliar one, since both look exactly the same from the side.

A side-on camera reads the vertical arc of a jump well and has no idea where the plant foot actually landed on the ground, which is usually the real question.

Some inward lean on the curve approach is correct high jump technique, the fault is starting it too many steps out, and film shows exactly when it begins.
