Endurance riding tests horses over distances of up to 160 kilometres in a single day. The welfare implications of this demanding sport have come under increasing scrutiny following high completion failure and mortality rates.
Endurance riding welfare depends critically on the relationship between rider capability, horse conditioning and race management. Well-conditioned horses ridden by experienced, welfare-conscious riders within their physiological limits can compete safely. Horses pushed beyond physiological tolerance by inexperienced riders or under competitive pressure experience genuine suffering and risk metabolic crisis. The mandatory veterinary gate system is an important welfare safeguard, but its effectiveness depends on assessment rigour and willingness to eliminate horses before crisis develops.
