The Slalom.
The slalom is built using 5 upright poles. These can be jump uprights, wings or even plastic electric fence posts. If using traditonal triangular / sloping wings, ensure that they are set so that the horse and rider will pass alongside the flat upright section and the slope is away from them.
Make sure any cups are removed from the wings.
The stands must be in a straight line with 7 metres between each.
You can use red and white tape on the tops (unless you have red and white wings / stands) to mark the course ensuring that you pass with red on your right, white on your left.
