Endurance racing pushes horses to extreme physical limits over long distances, creating significant welfare concerns about metabolic and musculoskeletal injury.
Endurance horses face welfare risks from metabolic exhaustion, dehydration, and musculoskeletal failure. Horses pushed beyond their physical limits develop rhabdomyolysis causing muscle breakdown and kidney failure. Colic risk increases during strenuous exercise. While mandatory veterinary checks catch some compromised horses, competitive pressure encourages riders to push horses that are showing early signs of trouble. End-stage metabolic collapse causes immense suffering.
