Pass the relay baton safely: downsweep exchange step by step, the takeover zone, distance and the typical mistakes that lead to disqualification.
In the downsweep exchange, the incoming runner pushes the baton from above into the outgoing runner's hand, which is stretched out behind. It works when three things are right: the outgoing runner keeps arm and hand calm, the incoming runner calls in time and pushes instead of slapping [2] — and the baton is still inside the 30-metre takeover zone when it changes hands [1]. An exchange outside the zone means disqualification [1].
The honest answer to why relays fail so often: not for lack of speed, but because of the exchange. In a calculation study on the 4×100 m exchange, 25.5 % of teams at the most recent World Championships at the time were disqualified or did not finish [4]. One team in four dropped out of the results before the clock even mattered.
And a bad exchange costs time. In six national-level sprinters, two variables together explained 55 % of the variance in the 30 m zone time: how fast the incoming runner enters the zone and how fast the outgoing runner already is when the handover begins [3]. A good exchange is no magic trick, it is timing at high speed.
The outgoing runner stretches the arm as far back as possible and extends the hand slightly [2]. What matters is that the arm stays calm and the hand does not bend. The palm faces up, so the incoming runner can place the baton in from above.
Milestone (practice standard): 10 exchanges in a row while standing, with the baton landing in the hand every time and without the outgoing runner looking.
The incoming runner gives a short call ("Hop!"), and the outgoing runner stretches the arm. A good distance is two arm lengths plus half a baton [2]. Then you push, you do not slap [2].
Milestone: 10 clean exchanges while walking, with the baton staying in the receiver's hand.
Runners 1 and 3 run on the inside of the lane through the bend and hold the baton in the right hand, runners 2 and 4 run on the outside and hold it in the left [2][6]. So the baton travels from right to left to right to left. In your club, practise every position, not only your favourite [2].
Milestone: you can say without thinking which hand you receive the baton in and which you hand it on from.
Now speed comes in. The outgoing runner is accelerating (trunk leaning forward), so the arm sits lower than when standing — you practise this best in build-up runs [2]. The outgoing runner starts on a visual signal, for example when the incoming runner reaches the check mark [2].
Milestone: 8 out of 10 exchanges in build-up runs work on the first attempt.
The baton has to be passed inside the zone. The pass starts when the receiver first touches the baton and ends when only the receiver holds it [1]. Where exactly in the zone you exchange is secondary for young athletes — arm position and push matter more [2]. Your check mark is individual: in a calculation study, the optimal mark lay between 11.04 and 12.20 metres, depending on the exchange and the lane [4]. Test it yourself and adapt it to your speed.
Milestone: 8 out of 10 exchanges inside the zone, without the outgoing runner braking or the incoming runner having to chase.
The exchange happens at high speed, so: warm up properly before every exchange at pace. Of 357 athletes before the 2018 European Championships, 48 % had had a hamstring injury at some point in their career, 24 % in the current season [7]. Sprinting is a real risk area — a cold start in the exchange is exactly what you do not need.
After the handover, stay in your lane until the track is clear [1]. That avoids collisions with other teams. With children or beginners, a mistake in the exchange is part of learning, not a drama [2].
This guide explains and motivates; it does not replace supervised training or training with a coach.
There are at least two families of exchange, and the rules prescribe neither: all that counts is where the baton is when it changes hands [1]. Besides the downsweep there is the upsweep, in which the baton is pushed into the hand from below. Japan's relay teams use it [6]; a 2017 article calls it more reliable, without disturbing natural arm movement or speed [5]. A conference talk by Scottish Athletics adds that it disturbs running rhythm less when the first attempt is missed [6]. Try both with your team before you commit — but never change the method shortly before a competition.
30 metres. In the 4×400 m relay and longer relays it is 20 metres [1]. The baton has to be passed inside this zone, otherwise disqualification follows [1]. For competitions, always check the current edition of the rules.
The runner who dropped it picks it up themselves. They may leave the lane for that if they do not shorten the distance. If the baton rolls forward or sideways, they must return to the point where it was last in their hand. If they follow this and impede nobody, it is not a disqualification [1].
Runners 1 and 3 hold it in the right hand and run on the inside, runners 2 and 4 hold it in the left and run on the outside [2][6]. The baton therefore changes sides with every exchange.
A good distance for the exchange is two arm lengths plus half a baton [2]. That is the distance between incoming and outgoing runner at the exchange, not the distance to the check mark.
Both are allowed [1]. The downsweep is the classic method; more recent contributions call the upsweep more reliable and less disruptive to running [5][6]. Neither is truly proven for recreational teams — try it in practice.
