Rider dislodgement events in U.S. steeplechase racing: participation outcomes in riders and horses

Steeplechase jockeys compete in high-risk races requiring horses and riders to clear fixed obstacles at speed. Although rider dislodgement events are recognized hazards, their incidence and participation consequences are not well characterized.

This retrospective observational study used publicly available race charts from United States National Steeplechase Association races (2023-2025). Dislodgement events were defined as falls or lost rider events. Incidence rates were calculated per 1,000 starts, and timber and hurdle races were compared using Poisson regression. Rider interruption was defined as ≥ 30 days, with censoring for incomplete follow-up. Horse outcomes were assessed using ≥ 60-day interruption and non-return to jump racing.

Among 3,072 starts involving 83 riders and 710 horses, 187 dislodgement events occurred (60.9 per 1,000 starts; 95% confidence interval (CI), 52.2 to 69.6). Rates were higher in timber than hurdle races (103.5 vs. 51.8 per 1,000 starts; incidence rate ratio 2.00, 95% CI 1.46-2.73). Of 173 evaluable events, 26 (15.0%) were followed by rider interruption. At the rider level, 19 of 44 riders (43.2%) experienced ≥ 30-day interruption, and 7 of 38 (18.4%) did not return to jump racing. Among horses with dislodgement events in 2023-2024, 26 of 111 (23.4%) had no subsequent jump-racing start through 2025, although some continued racing on the flat.

Rider dislodgement events were common and more frequent in timber races. Most riders returned quickly, but a subset experienced interruption or non-return. Participation-based measures may complement traditional injury surveillance in jump racing.
