Horse racing betting is all about good luck and great judgement – yet sometimes the jargon surrounding the sport can be tricky to decipher.
If you’re a newcomer to horse racing then fear not because Paddy Power is here to bring you up to speed with our Demystifying Racing catalogue of guides.
And one of the weirdest eccentricities in racing betting is Rule 4. This is an odd clause in horse racing that can sometimes catch punters unawares. And while it isn’t regularly used, knowing when Rule 4 in horse racing is being applied will certainly help you out in the future.
WHAT IS RULE 4?
So what’s Rule 4 all about? Well, Rule 4 is simply a deduction that is made to winning bets – often in horse racing – when the race is impacted by one or more horses not running. It is a fair method of recalculating bets that have already been placed when suddenly a horse (or horses) is withdrawn.
For example, if you bet on the second favourite to win a race at 5/1, but the favourite withdraws just before the race, then your chances of winning suddenly shoot up. To adjust for the non-runners, Rule 4 calculates what the true odds of each remaining horse now are.
Don’t worry, you won’t have to do anything when Rule 4 kicks in but it is worth being aware of the clause in case you’re banking on a specific return from the race.
DOES RULE 4 AFFECT MY PAYOUT?
If Rule 4 is implemented in a race you have bet on then your payout might be affected. However, this depends on the horse that withdrew and the size of the race. For example, if a horse priced at 33/1 withdraws from a race involving 18 runners then Rule 4 would not be implemented, as the effect on the rest of the field is minimal.
However, were the 7/2 favourite to withdraw from a race at Cheltenham involving just seven runners then Rule 4 would kick in. Effectively, the shorter the odds of the non-runner, the bigger the Rule 4 deduction becomes. Check out more with Paddy Power help here.

RULE 4 EXCEPTIONS
You can get a racing betting exception to Rule 4s if you bet on the ante-post markets. These are odds that are listed before the full race list is announced, and are often used by punters looking to bet on races weeks and months in advance.
HOW TO CALCULATE RULE 4
Calculating Rule 4 can be tricky–and realistically you’re not expected to do it yourself! It all depends on the price of the non-runner and the strength of the field. However, as a general rule this table explains the basic Rule 4 deductions.

Cheltenham Rule 4
Paddy Power has fired up the Non Runner Money Back machine once again for Cheltenham 2023. It means any horse that misses their race will have bets refunded to those unlucky punters. No Rule 4 will apply until after the final declarations that are 48 hours before race time.
