The counter relay is a kind of fun relay race for children,in which the team is divided into two equal subgroups,and the participants run towards each other. For example,a team of 8 people was divided into two subgroups of 4 people each. The subgroups are arranged in a column one at a time and placed opposite each other at a distance of 10 meters. The first participant of the first subgroup runs 10 meters and passes the baton to the first participant of the second subgroup,and he takes the last place in the column. The relay ends when both subgroups switch places,as if in a mirror image.
