What happens to racehorses when they retire? Approximately 2,500 horses leave British racing every year. Some go into breeding. Some are sold abroad. And a significant proportion need to find a new life entirely, which means retraining, rehoming and a whole network of specialist professionals who have built careers around this transition.
In 2025, over 15,000 former racehorses were registered with Retraining of Racehorses, British racing’s official aftercare charity. That is around 46% of the estimated 33,600 former racehorses in Britain. The aftercare challenge is substantial, and it generates careers that are varied and often deeply rewarding.
Why racehorses need specialist aftercare
A thoroughbred bred and trained to race is not the same animal as a leisure horse. The physical conditioning differs, the handling methods differ, and a horse accustomed to an intensive training environment can have a very different psychological profile from what most amateur riders encounter.
Retired racehorses may be highly forward-going, sensitive or reactive, and some carry physical issues from their racing career. They have spent their entire working life handled in particular ways. Retraining them for a second career demands a specific skill set that goes beyond general equine competence.
The careers involved
Retraining of Racehorses coordinates the welfare and rehoming of former racehorses across Great Britain. They work with a network of approved retrainers who assess horses, develop their training, and place them with suitable new owners.
Approved retrainers are typically experienced equine professionals, many self-employed, who charge fees for their services. The work involves assessing a horse’s temperament and physical condition. It means designing and implementing a retraining programme. And it means matching the horse to an appropriate new home and discipline.
Beyond retraining, there are careers in sanctuary work for horses that cannot be rehomed. Vets manage racing-related injuries into retirement. Others work in welfare monitoring, rehabilitation and education. There are also roles in sales, client support and rehoming coordination, all helping bridge the gap between the racetrack and the horse’s next life.
A levy on the industry funds aftercare through the British Horseracing Authority, sustaining the infrastructure around these roles.
Second careers for thoroughbreds
Former racehorses have gone on to successful careers in dressage, eventing, show jumping, polo, showing and general leisure riding. British racing data shows general leisure riding and dressage are the most popular second careers. Many thoroughbreds adapt well to a new discipline and go on to compete at a high level.
If you are an equine professional with the skills and temperament to work with thoroughbreds in transition, this is genuinely specialist, valued work. It asks for patience, observation, and feel as much as technical horsemanship. These are extraordinary animals, and the people who work with them will often find it among the most satisfying work of their careers.
