Summary
# Editorial Summary Nagy, Murray and Dyson's analysis of 1,435 FEI endurance ride starts across 11 venues identified distinct risk factors for the two most common elimination causes in 80–160 km events: horses lacking prior experience at greater distances were significantly more likely to be eliminated for lameness, as were those competing more than 90 days after their previous FEI ride, suggesting inadequate fitness maintenance between events. Metabolic eliminations followed a different pattern, with deep sand or soil surfaces substantially increasing risk (odds ratio 1.98) alongside higher entry numbers—factors suggesting cumulative fatigue and environmental stress rather than individual conditioning deficits. Venue emerged as a significant predictor for both elimination types, implying that unmeasured factors such as organisational standards, course difficulty variation, and rider intent (training versus competitive effort) play overlooked roles beyond documented terrain characteristics. For practitioners, these findings underscore the importance of strategic scheduling—spacing FEI rides adequately rather than clustering them to maintain lameness-protective fitness levels—and highlight that ground conditions warrant serious consideration when assessing both metabolic and orthopaedic risk at endurance competitions. The authors appropriately acknowledge that elimination represents a multifactorial endpoint; future prospective research capturing training history, previous injury records, and veterinary assessment data would substantially improve our ability to identify modifiable risk factors and support evidence-based preparation protocols.

Practical Takeaways
- •Allow adequate recovery time (>90 days) between FEI endurance rides and avoid competing in consecutive events to reduce lameness risk
- •Build progressive distance experience before attempting longer endurance rides, as horses with prior experience at greater distances show lower elimination risk
- •Be cautious competing on deep sand or soil surfaces in endurance rides, particularly in larger fields, as these conditions significantly increase metabolic failure risk
Key Findings
- •Venue, prior experience at greater distances (OR=0.82), and >90 days since last FEI ride (OR=0.78) were significantly associated with lameness eliminations
- •Venue, increasing number of entries (OR=1.008), and deep sand/soil surfaces (OR=1.98) significantly increased risk of metabolic eliminations
- •Decreasing racing frequency may reduce lameness elimination risk in endurance competition
- •Deep sand or soil terrain contributes to exhaustion and metabolic failures in 80-160 km FEI endurance rides
