Keeping Circles on Track - The equestrian’s quest for the perfect circle crosses all disciplines. For Western and English riders, geometry matters. Horse show judges expect to see circles of uniform size and curves ridden with the horse’s body shaped to follow the arc. In dressage and reining, riders must show a clear distinction between large and small circles. In working equitation, circles around barrels and figure-eights must be symmetrical. In equitation and horsemanship patterns, judges frown on oval-shaped “circles.” In all classes, judges will deduct marks for circles of inaccurate size and over-arced or counter-flexed body alignment.
