Summary
# Editorial Summary Between 1996 and 1998, The Jockey Club conducted a comprehensive three-year surveillance programme across all 59 British racecourses, recording veterinary incidents from 222,993 racing starts to establish baseline data on injury patterns, clinical problems and fatalities in both flat and National Hunt racing. Musculoskeletal injuries dominated the clinical events (1,937 of 2,358 incidents), with forelimbs accounting for 81% of limb injuries and flexor tendons or suspensory ligaments involved in nearly half of all limb problems; non-musculoskeletal issues included epistaxis (0.83 per 1,000 starts), exhausted horse syndrome (0.47 per 1,000 starts) and atrial fibrillation (0.20 per 1,000 starts). The overall fatality rate was 0.29% across all starts, but risk varied dramatically by discipline—chases recorded 24.7 incidents per 1,000 starts compared to just 3.97 for flat races on turf—and age emerged as a significant risk factor, with injury rates increasing progressively through a horse's racing career. Surface conditions significantly influenced outcomes, with softer going associated with fewer fatalities and injuries than firm ground, whilst interestingly total tendon injuries were higher in chases than hurdles despite age-corrected rates being higher in hurdles. These findings provide evidence-based data for practitioners to counsel clients on discipline-specific risks, inform training and racing decisions around surface conditions, and highlight the particular vulnerability of older racehorses and those competing in jumping disciplines.

Practical Takeaways
- •Forelimb soft tissue injuries, particularly affecting flexor tendons and suspensory ligaments, are the dominant injury pattern in racing — farriers and veterinarians should prioritize preventive strategies for these structures through surface selection and workload management
- •Chase racing carries significantly higher injury and fatality risk (6-fold higher than flat racing) — owners and trainers must weigh these risks when selecting racing types and implement enhanced welfare protocols for jump racing
- •Older horses carry substantially elevated injury risk — trainers should adjust training intensity and racing frequency based on age to mitigate this evidence-based risk factor
Key Findings
- •Of 222,993 racing starts, 2,358 clinical events (1.05%) were reported, with 657 incidents (0.29%) resulting in death or euthanasia
- •Musculoskeletal injuries accounted for 82% of all clinical events, with 81% of limb injuries involving forelimbs and 46% involving flexor tendons/suspensory ligaments
- •Chase racing had the highest incident rate at 24.7 per 1000 starts compared to 3.97 for flat races, with softer surfaces associated with fewer fatalities and injuries
- •Injury risk increased significantly with age, and tendon injury rates were paradoxically higher in hurdle races than chases despite chases having higher overall injury rates
