<!--Straight - The horse and rider backs through a straight corridor.

<!--"L" - comprised of a corridor shaped like an "L".  Competitor enters the corridor, rides to the end, halts, and then a rein back is executed back through the "L" shaped corridor.

<!--Slalom: comprised of 3 posts with a minimum distance of 3 meters between posts. The horse must perform a slalom backwards around the posts.
