What is a common indicator that a horse may not be fit to race?

Signs of lameness or behavioral changes are key indicators that a horse may not be fit to race. Lameness can manifest as a noticeable change in the way the horse moves, such as limping, uneven strides, or reluctance to perform certain movements. Behavioral changes can include increased agitation, signs of pain, or reluctance to engage in regular training activities, indicating discomfort or distress. Both physical and behavioral cues are crucial for trainers to assess a horse's overall health and readiness for competition. This vigilance helps in identifying issues early, potentially preventing further injury or poor performance during a race.

On the other hand, excessive energy and excitement could actually suggest that a horse is in good physical condition and ready to race, while consistency in performance during training typically indicates that the horse is fit. An increased appetite prior to a race can be seen as a sign of good health and readiness, further emphasizing why lameness and behavioral changes are the most significant indicators of a horse's unfitness for racing.
