The 4x100 metres is four sprints and three handovers, and history keeps showing that the handovers matter more. A perfect exchange at full speed is worth more than a tenth of raw pace — and a sloppy one has ended more medal dreams than any false start.

The exchange zone rewards repetition

Elite relay squads rehearse the pass hundreds of times before a championship, marking check-in points on the track and calibrating the outgoing runner's acceleration to the incoming runner's speed. The baton should change hands inside a single stride, with neither athlete looking back or breaking rhythm.

There are two schools — the blind push pass and the visual upsweep — and each squad picks the one its athletes can repeat under stress. The choice matters less than the commitment: mixed techniques inside one team are where fumbles are born.

Nobody remembers the second leg. Everybody remembers the dropped baton.

Drills that fix the most common errors

Late take-offs, reaching back, and drifting out of the lane cause most disasters. Coaches fix them with short-zone reps at 90 percent speed, verbal commands that never change, and film review of hand placement frame by frame.

For school and club teams, the lesson scales down cleanly: pick one method, practise it tired, and never improvise on race day. Chemistry in the zone beats talent outside it, every single time.

The takeaway: One method, one call, one hundred reps — then trust it when the stadium shakes.
