Our Q2 Metrics Report includes a new level of analysis: racing-related fatality rates by surface type.

🟨 Dirt: 0.93 fatalities per 1,000 starts (28,934 starts)
🟩 Turf: 1.41 fatalities per 1,000 starts (9,213 starts)
⬛ Synthetic: 0.40 fatalities per 1,000 starts (2,478 starts)

While HISA has not yet determined whether the data reflect persistent trends or quarter-specific variation, by establishing baseline data across surfaces, conditions and race types, we can better identify patterns and target future safety efforts.
