Horse-racing rules
What happens if a horse race changes surface from turf to all-weather?
Direct answer
Some bets stand under altered conditions; others are void if the market specifies a particular course or surface.
How to use this answer
A definitive win, loss, void or refund cannot be established from the question alone. Identify the operator, the exact market, the date and the relevant official result, then check the rules that applied to the bet.
Racing bets can have different dead-heat, withdrawal, non-runner and each-way settlement conditions. Confirm the race time, final official result and the operator’s rule that applied when you placed the bet.
