Beginner: 12-14 strides
Most middle school and freshman jumpers hit their top speed by stride 12 or 13, so anything longer just adds room to wobble. A short approach isn't a compromise, it's the correct approach for that speed level. Coaches who stretch a beginner's run-up to 18 strides because elite jumpers do it usually get a less consistent board hit, not a longer jump. Lock the length once it's consistent, then grow it as top speed grows, not before.
