Betfred does have dead heat rules. In horse racing and some other sports, a dead heat occurs when two or more participants finish a race or event with the same result, and it's not possible to determine a clear winner. In this case, the stakes are divided between the tied participants based on the number of winners.
Betfred's dead heat rules state that if there is a dead heat in a horse race, the stake will be divided by the number of winners and settled at the full odds. For example, if you bet $10 on a horse to win at odds of 5/1 and there is a dead heat with two winners, your bet would be settled as a $5 bet at odds of 5/1 for each winner, giving you a total return of $30 ($15 profit plus your $10 stake).
It's important to note that dead heat rules may vary depending on the sport and specific event, so it's always a good idea to check the rules and terms and conditions on the Betfred app to ensure you understand how dead heats will be settled for your specific bet.
