Endurance riding pushes horses to extreme physiological limits over distances up to 160km, with significant welfare risks when training, supervision, and veterinary oversight are inadequate.
Equine endurance welfare depends critically on training quality, rider skill, and the standard of veterinary vetting during events. Well-prepared horses in well-organised events with rigorous vetting show low complication rates. Poorly conditioned horses ridden by overambitious riders in events with inadequate veterinary controls suffer serious metabolic crises, muscle breakdown, and cardiac events. The difference between a welfare-positive sport and an abusive one is almost entirely determined by oversight quality.
