Horse Racing - Rule 4

If you receive less than expected from a horse racing win, your bet may have been affected by Rule 4. You can check this in your betting history.

What is Rule 4?

Rule 4 is a Tattersalls Rule of Racing. It means that when there is a late withdrawal of a horse (it’s listed as a ‘non-runner’), the payout on the other runners in the race will be decreased to compensate. This is because the starting odds no longer reflect each runner’s likelihood to win.

How much will the payout decrease by?

The decrease in payout depends on the odds of the non-runner at the time of its withdrawal. Every odds value corresponds to a deduction in pence per pound – the shorter the odds, the larger the deduction (see table below). This deduction is taken from every £1 of your winnings.

Example:

  • You place a bet of £10 on a horse at odds of 2.25, with a potential payout of £22.50 (winnings of £12.50 plus returned stake).
  • A horse with odds of 1.25 is withdrawn, and Rule 4 applies.
  • Your horse wins, but your winnings are reduced by 80p per every £1.
  • You receive £12.50 (winnings of £2.50 plus returned stake).
