The cones are laid out as per the diagram, with three marker cones placed in a arrowhead shape, and one set of cones or line marker to indicate the start and finish line. The player starts with their foot behind the starting line in a sprint start position. When ready, they run as fast a possible to the middle cone (A), turn to run around the side cone (C) or (D), around the far cone (B) and back through the start/finish line. The subject completes four trails, two to the left then two to the right (as shown). The trail does not count if they step over a cone instead of around it.
