Carried Out in thoroughbred horse racing means when a horse is forced to move toward the outside of the track by another rival horse during the race. This term describes a situation where a horse’s path is altered not by the jockey’s choice, but because another horse is pushing it outward, typically making the affected horse race wider than intended.
The term is interchangeable with “forced out” and can occur when another horse is either getting out or bolting, or when multiple horses across the track force a horse very wide to maintain contention. This movement toward the outside is generally disadvantageous because it means the horse must travel a longer distance around the track.
On racecards and in official race charts, “carried out” often appears abbreviated as “C” in the running comments.
