Summary
# Editorial Summary: Risk Factors for Thoroughbred Jumps Racing Fatalities in New Zealand Over the 2011/22 season, Gibson and colleagues analysed 8,970 race starts in New Zealand Thoroughbred jumps racing to identify modifiable risk factors contributing to fatalities, recording 51 deaths (5.7 per 1,000 starts), with fractures accounting for nearly 86% of these incidents. Using retrospective race-day data, the researchers examined horse, race and jockey variables, finding that the majority of fatal fractures resulted from falls during competition, with steeplechase and hurdle races showing comparable fatality rates (4.9 per 1,000 starts each). Distance emerged as a significant risk factor for steeplechase runners, with horses competing over 4,201 metres facing a five-fold increased likelihood of fatal fracture compared to shorter courses, whilst spring racing conditions in hurdles increased this risk 2.2-fold relative to winter fixtures. These findings provide racing authorities with concrete, evidence-based targets for regulatory intervention—particularly around course design and seasonal race programming—though the small number of cardiac and soft tissue fatalities limits the scope of risk stratification for these mechanisms. For veterinary and farriery professionals advising racing yards, this data reinforces the importance of pre-competition fracture risk assessment and conditioning protocols specific to distance and seasonal demands in jumps racing programmes.

Practical Takeaways
- •Track and race distance management are modifiable risk factors; consider regulatory restrictions on longer steeplechase races to reduce fatality risk
- •Seasonal risk variation in hurdle racing (higher spring risk) suggests environmental, ground condition, or training factors warrant investigation and management
- •Fall prevention and rapid intervention protocols should be prioritized, as falling accounts for the majority of fatal fractures in jumps racing
Key Findings
- •Race day fatality incidence was 5.7 per 1,000 starts in New Zealand Thoroughbred jumps racing (2011/12-2021/22), with fractures accounting for 4.9 per 1,000 starts
- •Steeplechase horses racing over 4,201 m were 5.0 times more likely to sustain fatal fractures than those in shorter races
- •In hurdle races, horses racing during spring were 2.2 times more likely to sustain fatal fractures compared to winter
- •70.5% of fatal fractures resulted from horses falling during races, with equal incidence between steeplechase and hurdle disciplines
