Many people know the basics of win or place bets, but there are other ways to predict how a race will finish. A dual forecast is one of them, commonly used in horse and greyhound racing.
This guide explains what a dual forecast bet is, how it works, how the odds are settled, and how it compares with similar markets. You will also find a clear worked example, plus when this bet might suit and pitfalls to watch for.
Throughout, the focus is on making informed choices and staying in control so betting remains measured and within budget.
How Does A Dual Forecast Work?
A dual forecast bet involves picking two selections to finish first and second in a race, in either order. If those two take the top two places, the bet wins, regardless of who finishes first.
It is not the same as backing two runners to place. The selections must be the exact top two. Dual forecast markets are typically available in races with at least three runners.
If that sounds straightforward, the natural next question is how it compares with similar forecast options.
Dual Forecast Compared With Forecast And Reverse Forecast
A dual forecast bet involves selecting two participants to finish first and second in any order.
In comparison, a standard forecast bet requires the bettor to pick the exact order of the top two finishers. For the bet to succeed, the first selection must win and the second selection must come second.
A reverse forecast allows for both possible finishing orders. This is essentially two separate forecast bets, covering both combinations. This means the bet covers both possible outcomes for the first and second places, but the total stake will be doubled because two bets are placed.
To summarise:
- Dual forecast: pick two to finish first and second in any order.
- Forecast: select two in the exact order.
- Reverse forecast: cover both possible orders with two bets.
With the differences clear, it helps to know how placing a dual forecast typically works on a betting site.
How To Place A Dual Forecast Bet
A dual forecast is placed by selecting a race, choosing the forecast market type, and nominating two runners to fill the top two positions in any order. On most betting sites, this sits within the forecast section of the race page. The two runners are added via the bet slip menu, a single stake is entered, and the bet is confirmed. Because both orders are covered within one wager, only one stake is needed.
It is always sensible to review the bet slip before confirming, ensuring the correct runners and stake are shown.
Once the mechanics are clear, the next piece of the puzzle is how the price for a dual forecast is worked out.
How Are Dual Forecast Odds Calculated?
Dual forecast odds are based on the starting prices of the two selections and the range of possible finishing combinations in the race. Bookmakers use a formula that factors in the chance of each runner finishing first or second, in any sequence, and then combines those probabilities into a single price.
This is why the dual forecast price is usually lower than simply multiplying the two win odds. It reflects that two finishing orders are being paid within one bet. In tightly matched races, where several runners have similar prices, the dual forecast odds often shorten to account for the wider competition.
Returns can vary between bookmakers, as some use slightly different calculation methods or apply deductions. Most sites display the estimated return on the bet slip before you confirm, so it is worth checking that figure.
With that in mind, a quick example makes the mechanics easier to see.
Examples Of Dual Forecast Bets With Simple Calculations
It is often useful to see how a dual forecast bet works in practice. Below is a clear, step-by-step example showing the process and how possible returns are calculated.
Step-By-Step Example With Numbers
Suppose a horse race has four runners: Horse A, Horse B, Horse C and Horse D.
A bettor chooses Horse A and Horse B for a dual forecast bet. The starting prices are:
- Horse A: 4/1
- Horse B: 6/1
The bookmaker uses a set formula to calculate dual forecast odds. In this illustration, the odds for the A-B dual forecast might be 14/1, though the actual price is often slightly lower than simply multiplying the individual win odds.
If someone places £2 on this dual forecast at 14/1 and either Horse A or Horse B finishes first while the other finishes second, the return would be:
£2 x 14 = £28, plus the original £2 stake, totalling £30.
The payout is only made if both horses take the top two places in any order, which is why understanding the market is key.
So, when might a dual forecast be the right fit compared with other ways to bet a race?
When Should You Use A Dual Forecast Bet?
A dual forecast may suit races where two entrants stand out on form, ratings or market support. In those situations, it offers a way to cover both possible outcomes for first and second without having to name the exact finishing order.
Bettors often look for races where the pair they like have strong recent performances, favourable conditions or consistent records at the distance. In smaller fields, or when the top two are a clear cut above on paper, a dual forecast can be a tidy option.
As with any bet, there are no certainties. Stakes should be kept within a set budget, with clear limits in place.
Common Mistakes With Dual Forecast Bets
There are a few errors that crop up regularly with this market. Being aware of them can help avoid frustration.
- Misunderstanding the bet: only the named pair finishing first and second, in any order, counts. Two selections simply placing is not enough.
- Overlooking field size: dual forecasts are typically offered only when there are three or more runners.
- Rushing the bet slip: not double-checking selections and the stake can lead to backing the wrong pair.
- Planning without the “both orders” point in mind: because the dual forecast covers either order within one wager, staking plans should reflect that structure.
If gambling starts to affect well-being or finances, seek support early. Independent organisations such as GamCare and GambleAware offer free, confidential help.
Used with care and a clear plan, dual forecasts can be approached sensibly by those who enjoy analysing races and predicting the top two.
