Non Runner No Bet (NRNB) is a common phrase in sports betting, particularly as big events approach. At first glance, it may seem technical, but it is essentially a rule that might change how your selections are treated if they do not take part.
This blog post explores what NRNB is, how it might affect bets, which markets tend to offer it, and examples from horse racing and football. You will also see how refunds work and the limitations that come with them.

What Does Non Runner No Bet Actually Mean?
NRNB is a term that hints at a certain type of protection for your stake. In simple terms, it involves a scenario where a selection does not end up participating in an event. When applied, the bet on that selection is not settled as a loss.
This is particularly relevant in situations where normal rules might treat non-participation differently. For instance, in markets placed well before an event, such as ante-post horse racing, a withdrawn horse would normally result in losing the stake. NRNB changes how this is handled, which we will explore in the next section.
It is important to note that NRNB is only available when a bookmaker explicitly offers it. If a market does not display NRNB, the standard rules of the event apply.
How Does NRNB Work In Sports Betting?
When a market carries NRNB, and a selection does not take part, your stake on that selection is returned. This refund usually occurs once the bookmaker confirms the non-participation.
For multiple bets, NRNB only applies to the selection that does not participate. For example, if you place a four-fold accumulator and one selection is withdrawn under NRNB, that leg is removed, and the remaining three are recalculated at their original odds. This turns a four-fold into a treble, a treble into a double, and so on.
It is worth reiterating that NRNB applies only to markets that clearly display it. If it is not mentioned, standard settlement rules apply, which might differ for ante-post or early markets.

Which Bets Qualify For Non Runner No Bet?
NRNB is most often available on selected markets rather than across all events. Common examples include:
- Major horse racing festivals: For ante-post bets on prestigious meetings such as the Cheltenham Festival, Royal Ascot, or the Grand National, NRNB ensures that if a horse does not take part, the stake is returned. This might occur due to injury, illness, or unsuitable conditions.
- Tournament outrights in football: If you back a team to win a major tournament, NRNB might return your stake if the team does not participate, for instance, due to disqualification or failure to qualify.
- Selected player outrights: Bets on awards like top goalscorer or best player might include NRNB if the individual does not take part, as specified in the market terms.
NRNB can apply to singles and multiples, but it is not universal. For multiples, only the legs explicitly covered are affected. In-play bets or very short lead-time markets rarely carry NRNB because confirming non-participation quickly might be difficult.
A simple check is to look for a label or note on the market. No label generally means standard rules are in effect.
How Are Stakes Refunded With NRNB?
The refund process is fairly straightforward once NRNB is applied:
- Singles: If the selection does not take part, your stake is returned after confirmation. In horse racing, this is usually around final declarations. In football or other tournaments, refunds follow official squad or participant announcements.
- Multiples: Only the non-participating leg is removed, with the remaining selections recalculated at their original odds. For example, a four-fold becomes a treble if one selection is withdrawn.
- Free bets or bonuses: Refunds depend on the offerβs terms. Some bookmakers return cash, others credit bonus funds.
While procedures vary slightly between operators, the principle is the same: if a selection does not participate, the stake is returned rather than settled as a loss.
Examples Of NRNB In Horse Racing And Football
Horse Racing
Imagine you place a bet on a horse for a major festival weeks in advance, with NRNB applied. If the horse is withdrawn, the stake is returned. If it were part of a four-fold accumulator, the bet is recalculated as a treble with the remaining three horses. The odds are recalculated based on the original values for those remaining selections. This allows for adjustments if the horse cannot compete due to injury or unsuitable conditions.
Football
NRNB might also apply to tournament outrights. If you back a team to win a summer tournament and they do not take part, the stake is returned. Similarly, selected player outrights such as top goalscorer bets might be protected under NRNB if the player does not participate. In each case, the principle mirrors horse racing: non-participation triggers a return of the stake, while active selections continue to be settled normally.
Are There Any Limitations Or Exceptions With NRNB?
NRNB is not automatically applied to all markets and comes with important limitations:
- Market selection: Bookmakers decide which events carry NRNB. Some markets might cover only singles, not multiples.
- Timing: NRNB might be valid only within a particular window. Bets placed close to the start or in-play are often excluded.
- Event changes: Postponed, rescheduled, or materially altered events generally follow standard settlement rules rather than NRNB.
- Other rules: In horse racing, adjustments such as Rule 4 deductions for withdrawals still apply even if NRNB is offered.
- Participation vs performance: NRNB applies only if a selection does not take part. If a participant starts but fails to finish, standard rules govern settlement.
Always follow responsible gambling practices. Only stake amounts you are prepared to lose, set limits, and seek help if gambling affects your well-being or finances. Organisations such as GamCare and GambleAware provide guidance and support.
By understanding NRNB, you might make more informed decisions if you choose to bet on events where non-participation is a possibility. Checking market terms, recognising when NRNB applies, and understanding refunds ensures a clearer betting experience while still allowing settled selections to continue normally.
