What is NRNB in ante-post betting? Learn how Non Runner No Bet works before Cheltenham, when bookmakers introduce it, and whether it’s worth taking shorter odds for reduced risk.
Ante-post betting is a form of wagering where bets are placed on an event well in advance of the final declarations. Also known as futures or outright betting, this is very common in sports betting, particularly in horse racing when the biggest events come around such as the Cheltenham Festival.
The term "ante-post" is derived from Latin and translates to "before the post", which is referring to the historical betting post or starting post on a racecourse. In ante-post betting, punters can place their wagers weeks or months before the event occurs, with this type of betting normally offering higher odds but added risk as more information will be known closer to the time.
There are many reasons why Cheltenham Festival markets open months in advance, as ante-post bets allows you to find the top value in your selections, due to being able to capatalise on favourable odds before they shorten closer to the event. For example, if you have a strong opinion or insight into a horse or team at the festival, ante-post bets allow you to back that success before the market fully reflects it.
Another reason they open so early is down to long-term engagement with Cheltenham Festival, as you could place a bet months before the event, and in doing so keep that excitement and intrest from then until the bet is settled. Lastly, and perhaps the most important reason that we mentioned earlier, is that the odds are often higher in ante-post markets but that comes in exchange with more uncertainty.
The main risk is that your selection ends up not running in the race you backed them in, or not at all, as there can be last minutes changes to entries or injuries prior to the festival. However, Non Runner No Bet (NRNB) has changed the dynamic in recent years, as most reputable bookmakers will offer this type of insurance which means if your selected horse does not run for any reason, your stake is fully protected.
As a result, it means punters can enter the ante-post market with full confidence and less risk, knowing that they have the freedom to bet on a horse without losing your money if it does not run.
What Is NRNB in Ante-Post Betting?
In standard ante-post betting, it works by placing a bet on a race well before the final declarations, with the biggest meetings such as the Cheltenham Festival often allowing wagers months in advance. The upside is the chance to lock in bigger odds, but if your horse does not run for any reason, your stake would be lost.
However, when NRNB is applied, that risk disappears. It means you can still secure the early price, but if your horse fails to run your stake is refunded by the bookmaker instead of lost. Bookmakers normally introduce NRNB for Cheltenham in between January and March, once the likely runners are clearer, however bear in mind that odds under NRNB will be slightly shorter but offer a much safer bet.

| Feature | Standard Ante-Post | NRNB Ante-Post |

| Risk level | High | Reduced |

-
Safer for injury-prone horses – ideal when backing runners with a history of missing targets or fragile profiles

NRNB Ante-Post Strategy: When Should You Bet?
NRNB ante-post betting is most effective when there's a balance between price value and runner certainty. Many consider January onwards as the sweet spot for this, when trainers have clearer plans and bookmakers begin to offer NRNB on major races at Cheltenham Festival.
At this stage, you can still grab an early price but without taking on the full non-runner risk that comes with traditional ante-post bets. The three main things to consider is whether you selection is highly likely to run in a specific race, it has strong recent form, and the price is expected to shorten closer to the festival.
NRNB is especially useful if you fancy a horse that’s popular in the market but still has multiple race options, as you get rewarded if it runs, and protected if trainers choose a different target. In short, NRNB suits bettors who want to play early, but not blindly, by combining enhanced value with risk control.
Best Races for NRNB Ante-Post Betting
When looking at the races to target for NRNB ante-post betting, the most effective scenario is where there's high demand, strong betting interest and some uncertainty surrounding the runners.
For example, Championship races such as the Cheltenham Gold Cup or Champion Hurdle are good to target, as these often attract predictable line-ups and early markets with NRNB allowing you to lock in odds without worrying too much about late changes.
While Novice divisions are slightly more unpredictable with horses potentially competing for the first time at the festival, NRNB takes away the risk and protects your stake if a horse misses its intended debut. The Turners Novices' Hurdle and Brown Advisory Novices' Chase are two good ones to keep an eye on.
Lastly, if you are looking to bet on any Handicaps you may find these are slighty tricker, with runners being less predictable. This usally means bookmakers will introduce NRNB later in the ante-post season once the entries are clearer. As we approach the festival, the Ultima Handicap Chase may be a solid choice to consider.
NRNB vs Standard Ante-Post: Which Is More Profitable Long-Term?
Any bets with NRNB applied is generally considered more profitable for the average punter, especially with the unpredictability of the Cheltenham Festival. It offers the best balance between securing high eaely odds while taking away the risk of losing your stake if your chosen horse does not compete.
Standard ante-post wagers may offer the highest possible price but the risk of a non-runner losing your entire stake outweighs the potential.
Our advice for Cheltenham Festival would be to enter the ante-post market around January or early February to give yourself the best chance of locking in high odds and with the security that comes with NRNB.
FAQs
What does NRNB mean in ante-post betting?
NRNB stands for Non-Runner No Bet. It means if the horse you back does not take part in the race, your stake is refunded in full. This removes the biggest risk of ante-post betting, picking a horse that never lines up, while still letting you secure early odds.
What happens to my bet if my horse is a non-runner?
If your bet was placed under NRNB rules and your horse does not run, your stake is returned. The bet is treated as void and you can use your refunded stake to bet again on the race if you wish.
What happens to ante-post bet if horse withdrawn?
It depends on the terms when you placed the bet.
- With NRNB: Your stake is refunded if the horse is withdrawn.
- Without NRNB: Your stake is lost if the horse does not run, even if it is withdrawn days or weeks before the race.
This is why NRNB is particularly valuable for long-range Cheltenham betting.
When do bookmakers offer NRNB for Cheltenham?
Most bookmakers introduce NRNB close to the Festival, typically 2–4 weeks before the start of the Cheltenham Festival. Some firms may switch to NRNB earlier for major races like the Champion Hurdle, Gold Cup or Supreme Novices’ Hurdle, especially once final entries are clearer.
Is NRNB better than standard ante-post betting?
For most bettors, yes. NRNB offers extra protection because you don’t lose your stake if the horse doesn’t run. Standard ante-post betting can sometimes offer bigger prices, but it comes with the risk of losing your bet if the horse is ruled out.
Are NRNB odds lower than normal ante-post odds?
Usually, yes. Due to NRNB removing the non-runner risk for the bettor, bookmakers often shorten prices slightly compared to standard ante-post odds. In return, you get insurance against withdrawals, which can be especially valuable during a Festival where ground conditions and race targets often change.
