The process of transitioning a racehorse to a new career after it retires from racing involves several steps, including a period of rest, rehabilitation, and retraining. The horse must be given time to recover from any injuries sustained during racing, and then gradually introduced to new activities and training methods that are appropriate for its age, temperament, and physical condition..

Ex-racehorses can be retrained for a variety of careers, including show jumping, dressage, eventing, trail riding, and therapeutic riding. Some may also be suitable for careers in law enforcement or as polo ponies, depending on their temperament and training.

Retraining ex-racehorses can be a challenging process, as these horses may have been trained to run at high speeds and may not be familiar with other types of activities. They may also have physical or behavioral issues that need to be addressed, such as muscle imbalances, stiffness, or anxiety. Patience, consistency, and a deep understanding of horse behavior and training methods are essential to successfully retrain an ex-racehorse.

There are many organisations that specialize in re-homing ex-racehorses, such as the Thoroughbred Aftercare Alliance and the Retired Racehorse Project. These organizations offer a variety of resources and programs to help individuals find and adopt ex-racehorses, including adoption clinics, training workshops, and financial assistance.
