“Ducked In Gap” in thoroughbred horse racing describes when a horse ducks into a gap between the temporary railing put up for some races that come out of a chute, then makes a sharp left-hand turn onto the main track.

Track Configuration Context
This term is specific to races that start from a chute – a straight extension of the track that allows for longer race distances. When horses exit the chute and turn onto the main track, temporary railings are installed to guide the field properly.

What Happens
When a horse “ducked in gap,” it means the horse veered off the intended path and went through an opening in the temporary barrier system rather than following the prescribed route with the rest of the field. This creates a significant positional disadvantage as the horse must be redirected back onto the proper racing surface.

Racing Implications
This maneuver typically results in the horse being well behind the rest of the field after being straightened back onto the correct course. It’s considered a trip excuse that can explain poor performance, as the horse loses valuable ground and momentum during this deviation.

This term represents one of the more specific track-related incidents that can impact a horse’s chances, particularly in races utilizing chute starts where the transition from straight to oval creates opportunities for such navigation errors.
