Transforming retraining: Supporting racehorses to have successful second careers.

Abstract: Optimizing long-term welfare outcomes for Thoroughbred racehorses following retirement from racing is a priority across the global horse racing industry. Following their racing career, horses are required to adapt to a markedly different lifestyle, involving substantial physical, behavioural, and mental adjustment. This study consulted experienced retrainers to identify factors that inform successful retraining and transition of former racehorses to promote positive lifelong outcomes beyond racing. An online survey of 100 global stakeholders experienced in retraining former racehorses explored common challenges, practices, and perceptions associated with transition. The survey results informed a subsequent Delphi consultation involving 27 experienced racehorse retrainers and musculoskeletal therapists, to establish consensus on which factors were essential to underpin successful transition. Survey data were analysed using frequency analysis and inductive content analysis, while the Delphi consultation used content validity ratios to determine consensus across behavioural, physical, exercise, and management domains relevant to retraining. Survey respondents identified four key themes influencing successful retraining outcomes: the time allocated for retraining, the people involved in the process, the horse's prior racing and management history, and the overall approach taken to retraining. The Delphi consultation achieved consensus on seven areas considered essential to successful transition: feeding regime, rider skill, handler expertise, type of exercises undertaken, assessment and modification of the horse's shape, assessment and modification of posture, and provision of turnout. These findings emphasize the importance of addressing both physical and mental adaptation during transition. The versatility of Thoroughbreds was evident, with retrainers commonly preparing horses for eventing, dressage, and leisure riding homes. Successful transitions closely aligned individual horse capabilities with future owner expectations. Participants highlighted the need for increased owner education, improved access to professional expertise, and greater financial support for retrainers. Implementing evidence-informed, multidisciplinary transition pathways may enhance retraining practices and promote sustainable, positive outcomes for former racehorses beyond racing.

Transforming retraining to support Thoroughbred racehorses in their transition to successful second careers after racing is crucial for their long-term well-being. This study gathered insights from experienced retrainers worldwide to identify key factors and best practices that promote positive outcomes during and after the retraining process.

Research Background and Objective

  • Thoroughbred racehorses face significant physical, behavioural, and mental adjustments when retiring from racing.
  • The racing industry prioritizes optimizing welfare for retired racehorses through effective retraining and transition.
  • This study aimed to consult experienced retrainers to uncover factors influencing successful retraining and transition to second careers.

Methodology

  • An online survey was conducted with 100 global stakeholders experienced in retraining former racehorses to gather information on challenges, practices, and perceptions.
  • The survey data were analyzed using frequency analysis and inductive content analysis to identify common themes.
  • A Delphi consultation followed, involving 27 expert retrainers and musculoskeletal therapists, to reach consensus on essential factors for successful transition.
  • The Delphi method employed content validity ratios to determine agreement across multiple domains: behavioural, physical, exercise, and management.

Key Findings from the Survey

  • Four main themes influencing successful retraining were identified:
    • Time allotted for retraining: Adequate duration is vital for physical and mental adjustments.
    • People involved: The skills and knowledge of those retraining and handling the horse critically affect outcomes.
    • Horse’s prior history: Previous racing and management practices impact the horse’s adaptability.
    • Overall retraining approach: Tailored, holistic strategies promote better transitions.

Consensus from the Delphi Consultation

  • Seven essential factors identified for successful transition:
    • Feeding regime: Proper nutrition supports health and retraining progress.
    • Rider skill: Experienced riders influence confidence and adaptability in horses.
    • Handler expertise: Skilled handling ensures physical and mental welfare during retraining.
    • Type of exercises undertaken: Appropriate activities are critical for physical conditioning and behavioural adjustment.
    • Assessment and modification of the horse’s shape: Addressing conformation helps prevent injury.
    • Assessment and modification of posture: Proper posture correction improves movement and comfort.
    • Provision of turnout: Regular turnout benefits mental well-being and reduces stress.

Implications and Practical Applications

  • Successful transitions depend on both physical and mental adaptation processes.
  • Thoroughbreds demonstrate versatility, often retrained for eventing, dressage, or leisure riding.
  • Aligning retraining plans with each horse’s individual capabilities and the expectations of future owners is key to positive outcomes.
  • There is a strong need for:
    • Enhanced owner education about retraining needs and horse capabilities.
    • Improved access to professional expertise in rehabilitation and training.
    • Greater financial support for retrainers to facilitate quality transitions.
  • Adopting evidence-based, multidisciplinary retraining pathways can improve the sustainability and welfare outcomes of retired racehorses.
