How can trainers evaluate the training regimen's effectiveness?

Utilizing performance improvements over time is the most effective way for trainers to evaluate the effectiveness of a training regimen. This approach takes into account various factors that contribute to a horse's overall development, such as stamina, endurance, and skill enhancements, rather than focusing solely on one particular aspect, like speed. By tracking the progress of a horse in terms of its performance in races or training sessions, trainers can identify patterns, pinpoint areas of improvement, and adjust the training program accordingly to achieve optimal results.

This method provides a comprehensive view of a horse's capabilities and growth, allowing trainers to make informed decisions about training adjustments, race placements, and recovery needs. It reflects the understanding that a horse's performance is multifaceted and depends on consistent improvement rather than sporadic results.
