Why does my relay team lose time on a clean baton exchange?

A clean handoff and a fast handoff are not the same thing, and the gap between them is almost always standing still, not a dropped baton.

Nobody drops the baton. Nobody steps on a line. The exchange looks fine to every parent on the fence, and the team's split still comes back slower than the sum of what each runner can do alone. That gap has a specific cause, and it is almost never the pass itself.

Clean is not the same as fast

A baton exchange has one job: move the stick between two athletes without either of them slowing down to do it. The 20-metre zone exists so that can happen at speed rather than at a standstill. When teams lose time inside it, the baton usually changed hands without incident while both runners were moving at two different speeds, not the same one.

• The go-mark was set from a walk-through at half speed, so it no longer matches the incoming runner's real closing speed on race day.
• The outgoing runner looks back to check the baton is coming, which costs a stride of acceleration every time.
• The grip does not match: one runner reaches with the hand the other expected the baton in, so there is a small adjustment that does not drop it but does slow it.
• The exchange happens in the back half of the zone instead of the front, so the pass lands when the outgoing runner has barely built speed.

Time the zone itself, not just the race

The easiest way to find out which of those it is: put one phone at the start of the exchange zone and one at the end, the same way you would time a flying 30, and clock the zone on its own. If that split is slower than either runner's open speed over the same distance, the fault is in the exchange, not the fitness. If it is close to their open speed, the baton is not the problem and the fix is elsewhere.

Film each runner's part of the exchange on the sprint setting: the outgoing runner's first steps for overstride and knee drive, the incoming runner's final strides for whether their form is holding or already breaking down from fatigue. StatLap does not have a relay-specific mode, so this is two sprint clips, not one.

What a single 2D camera cannot tell you: whether two runners are actually matched in speed at the moment of the pass. One camera, one angle, cannot hold both athletes in frame at a useful size while reading either one's mechanics, and relative speed between two moving bodies is not something a side-on lens reports as a number. Timing the zone with two phones gets you the number instead.
