The warm-up ring is sufficiently large (70 x 30 m) and there are two oxers and one upright fence available for the riders. At times there are between 15 – 18 riders warming up their horses, so it is crowded but not too crowded. When there are only 6 riders left in the class one of the grooms in the warm-up starts to build a combination.
You as President of the class are informed by the CS, what is your decision?
In what kind of classes is a good idea to build a combination at the warming up arena?
