What is the changeover technique in the relay?
The changeover technique in the relay is where one must exchange the baton within a specified distance. The distance of different athletes might vary as the outgoing runner can achieve maximum acceleration at different distances. For example, in my own case I feel that I can achieve full acceleration within 210 metres as I feel that 200 metres is not too much for me. The exchange of the baton requires a matching of the speeds of the incoming and outgoing athletes so that they are together towards the end of the changeover zone. This requires the outgoing runner to commence his/her run when the incoming runner reaches a check mark.
What are the changeover zone rules?
In all relay races, the baton should be passed within the change-over zone. The passing of the baton commences when it is first touched by the receiving competitor and it is completed the moment it is in the hand of the receiving competitor only. Within the change-over zone, it is only the position of the baton which is decisive, and not the position of the body or limbs of the competitors.
