What is Non-Runner No Bet?
Non-Runner No Bet (NRNB) is a bookmaker concession that protects your stake. If you back a horse on NRNB terms and that horse does not run in the race, the bet is void and your stake is returned, you lose nothing.
It removes the single biggest risk of betting on a race in advance: the chance that your horse simply never makes it to the start.
Why it matters for ante-post betting
To see the value of NRNB, compare it with true ante-post betting. When you bet ante-post, often weeks or months ahead, you usually get bigger odds, but you take on a real risk: if your horse is withdrawn, injured or simply not entered, the stake is lost, with nothing back.
NRNB changes that equation. On NRNB terms you keep much of the early-price value but remove the non-runner risk. The trade-off is that NRNB prices are usually a little shorter than pure ante-post prices, because the bookmaker is carrying that risk instead of you.
A worked example
You back a horse for a big spring festival race at 20/1:
- Pure ante-post: if the horse is withdrawn before the race, your stake is lost.
- NRNB terms: if the horse is withdrawn, your stake is returned in full.
When NRNB applies
Bookmakers generally move a major race onto NRNB terms in the days or weeks before it, once the likely field has firmed up. Earlier than that, prices are typically true ante-post. The switch date varies by bookmaker and by race, so always check the terms attached to the specific market before betting.
