What "ante-post" means
An ante-post bet is one placed before the final declarations for a race — in the Festival's case, anything from the day after one Festival ends to 48 hours before the race in the next one. You are betting on a horse that has not been confirmed to run, at a price that reflects that uncertainty.
The defining rule: if the horse does not run, the stake is lost — unless the bookmaker offered non-runner no bet (NRNB) on the bet. That one rule drives everything else on this page.
The stake: four scenarios
| What happens | Standard ante-post bet | NRNB ante-post bet | Day-of-race bet |
|---|
| Horse runs and wins | Paid at the price taken | Paid at the price taken | Paid at price taken or SP (bigger of the two with Best Odds Guaranteed) |
| Horse runs and loses | Stake lost | Stake lost | Stake lost |
| Horse declared but withdrawn | Stake lost | Stake refunded | Stake refunded; Rule 4 may apply to other bets |
| Horse never entered, injured, or sent to another race | Stake lost | Stake refunded | Not applicable |
NRNB prices are usually a little shorter than the standard ante-post prices from the same bookmaker. You are paying for the refund.
The timeline: September to March
| Period | What is happening | What it means for the market |
|---|
| September–October | Horses return from summer breaks; plans are talked about rather than fixed | Thin markets; big prices available on horses nobody has confirmed a target for |
| November–December | The season's first major graded races on both sides of the Irish Sea | The first firm evidence; prices move sharply on winners and losers of these trials |
| January | Cheltenham's Trials Day meeting and other key trials; search interest in Festival markets rises | Targets firm up; markets deepen; some bookmakers start offering NRNB |
| February | Final trials; entries for the championship races are published | Peak ante-post activity; the shape of each race becomes visible |
| Early March | Final confirmations | Non-runner risk falls but has not gone |
| 48 hours before each race | Final declarations | Ante-post market closes; day-of-race market opens with NRNB as standard |
| 16–19 March 2027 | The Festival | — |
Exact dates for entry and confirmation stages are set by the racing authorities each season and published in the official conditions; we will add them to this page once the 2027 dates are confirmed.
The arithmetic of non-runner risk
A price is an implied probability: 8/1 implies 1 ÷ 9 = 11.1%. For an ante-post bet to break even in the long run, the horse has to win at least 11.1% of the time including the occasions on which it does not run at all.
Suppose you judge there is a 20% chance the horse will not line up (injury, ground, a different target). Then for the bet to break even, the horse must win 11.1% ÷ 0.8 = 13.9% of the times it actually runs — which is the equivalent of a day-of-race price of about 6.2/1. In other words, taking 8/1 in September on a horse with a one-in-five chance of missing the race is the same bet as taking about 6/1 on the day with a stake refund guarantee.
| Ante-post price | Implied probability | Break-even win rate if 10% chance of non-running | If 20% | If 30% |
|---|
| 2/1 | 33.3% | 37.0% | 41.7% | 47.6% |
| 4/1 | 20.0% | 22.2% | 25.0% | 28.6% |
| 8/1 | 11.1% | 12.3% | 13.9% | 15.9% |
| 16/1 | 5.9% | 6.5% | 7.4% | 8.4% |
| 33/1 | 2.9% | 3.3% | 3.7% | 4.2% |
The table is why ante-post betting on short prices is so hard to justify: a 2/1 September favourite with a 20% non-runner risk has to win almost 42% of the time it runs just to break even. The same 20% risk on a 33/1 shot only lifts the required win rate from 2.9% to 3.7%.
When value might exist
- You know something the market has not priced. A trainer's stated plan, a horse's proven form on soft ground when the market is pricing a dry spring, or a trial result the market has over- or under-reacted to.
- The horse has one obvious target. A horse with a single realistic Festival race has a far lower "wrong race" non-runner risk than one entered in three.
- The price is big enough to absorb the risk. Per the table above, non-runner risk costs little at 16/1 or 33/1 and a great deal at 2/1.
- NRNB is available at a price close to the standard book. Then you get most of the upside with the downside removed.
When it usually does not
- Short-priced favourites in September. The price is small, the risk is uncompensated and the horse can be beaten by anything that happens over six months.
- Horses with several entries. Until the yard commits, you are guessing which race — and the stake is lost if you guess wrong.
- Races the market prices late. For 2027 we have found no verified third-party ante-post market at all for the Champion Chase or Stayers' Hurdle; there is nothing to take a view on yet.
- When the day-of-race book will be more generous. Big-field handicaps often carry enhanced each-way terms on the day that do not exist ante-post — see each-way betting.
- When you cannot afford to have the money tied up until March. An ante-post stake is illiquid; you cannot normally cash it out at a fixed-odds bookmaker.
The 2027 markets as of 14 September 2026
Third-party reports have quoted indicative prices for two of the four championship races. These are not live odds from a named bookmaker and appear here only so that you can see the shape of the markets.
| Race | Reported favourite | Others named | Seen |
|---|
| Gold Cup | Gaelic Warrior, about 2/1 | Jango Baie about 7/1; Final Demand about 16/1; Fact To File about 18/1; Lulamba, Kitzbuhel, Inothewayurthinkin about 20/1 | 21 July 2026 |
| Champion Hurdle | Lossiemouth, about 5/2 | Mydaddypaddy about 14/1; Old Park Star about 16/1 | 9 June 2026 |
Apply the table above: a 2/1 favourite six months out needs to win well over 40% of the time it runs to justify a standard ante-post bet if you put the non-runner risk at 20%. Whether Gaelic Warrior — an eight-length winner in 2026 and a record-equalling fifth Gold Cup for Willie Mullins and Paul Townend — clears that bar is a judgement, not a fact.
Pre-bet checklist
- Is NRNB available? If yes, at what price relative to the standard book?
- How many entries does the horse hold? One clear target or several?
- What is my honest non-runner estimate? Put a number on it and run the table.
- Is the price above break-even after that adjustment?
- Will the day-of-race market offer better terms (extra places, Best Odds Guaranteed)?
- Can I leave the stake untouched until 19 March 2027?
- Have I recorded the price I took? Our own tips are recorded with the price at publication and never deleted — see how our tips work.
