Greyhound Forecast Bet Explained — Straight, Reverse & Combination

First and Second, in That Order

A forecast asks you to be right twice — in sequence. You name the dog that will cross the line first and the dog that will finish second, and both must land in exactly the positions you predicted. Get one right and one wrong, and the bet loses entirely. Reverse the order by accident, and you’ve lost again. There is no partial credit.

That severity is precisely what makes forecast betting attractive. Because the probability of nailing two finishers in order from a six-dog field is significantly lower than simply picking a winner, the returns can be substantial — often far exceeding the combined odds of the two individual selections. A forecast between a 3/1 shot and a 5/1 shot won’t simply pay at combined odds of 15/1. The actual dividend is calculated by the tote or by a computer forecast model, and it can land anywhere from 10/1 to 50/1 or more depending on how the rest of the field was expected to perform.

Forecasts sit in the middle ground between the simplicity of a single win bet and the extreme difficulty of a tricast. For punters willing to study race shape and trap dynamics rather than just individual form, they offer a path to larger returns without requiring the near-impossible precision of predicting three finishers in order.

What separates profitable forecast punters from hopeful ones is understanding the three distinct variants available, knowing what each costs, and deploying them in the right situations.

Straight, Reverse, and Combination Forecasts

Three forecast variants, three different risk-reward profiles. The straight forecast, the reverse forecast, and the combination forecast all ask you to predict the first two finishers — but they differ in how much flexibility they give you, and what that flexibility costs.

The straight forecast (SFC) is the purest form. You select dog A to win and dog B to finish second, in that exact order. One bet, one unit stake. If A wins and B is second, you collect. Any other outcome — including B winning and A second — and you lose. The payout is calculated by the computer straight forecast (CSF) model, which factors in the starting prices of all runners to generate a dividend. CSF returns in greyhound racing routinely range from £10 to £100+ for a £1 stake, depending on how predictable the result was.

The reverse forecast (RFC) doubles your flexibility — and doubles your cost. You select two dogs, and your bet covers both possible finishing orders: A first with B second, or B first with A second. An RFC is simply two straight forecasts packaged together, so a £5 reverse forecast costs £10. If either arrangement comes in, you collect the CSF dividend on the winning combination. The advantage is obvious: you don’t need to predict which of your two selections beats the other, only that they fill the first two places between them. The disadvantage is that your cost doubles while your return stays the same as a single SFC.

The combination forecast (CFC) extends the principle further. Instead of two dogs, you select three or more, and the bet covers every possible first-and-second pairing among your selections. This is where costs escalate rapidly. Selecting three dogs in a CFC produces six possible straight forecast combinations (A-B, B-A, A-C, C-A, B-C, C-B), so a £1 CFC on three dogs costs £6. Four dogs produce twelve combinations at £12. Five dogs produce twenty combinations at £20. The maths scales fast.

Combination forecasts appeal to punters who are confident they can identify the right dogs but uncertain about the exact order. In an open greyhound race where three runners look clearly superior to the rest, a CFC covers all the outcomes that matter. But the expanded coverage comes at a price that demands larger dividends to generate profit.

Calculating the Cost of Your Forecast

Combination forecasts multiply quickly — know the cost before you commit. The formula is straightforward: for a combination forecast with n selections, the number of bets is n × (n − 1). Each of those bets costs your unit stake.

At first glance, a £1 CFC on three dogs at £6 total seems manageable. But context matters. If the three dogs you’ve selected are all in the top half of the market — say a 2/1 favourite, a 3/1 second favourite, and a 4/1 third pick — the resulting CSF dividend when two of them fill the first two places is likely to be modest, perhaps £8 to £15. At £6 outlay, you need the dividend to exceed your cost every time you land one, and forecast hit rates are low by nature.

The practical guideline is this: forecast betting works best when at least one of your selections is at a bigger price. A combination including a 7/1 or 10/1 shot produces dividends that comfortably justify the cost of coverage. Two favourites in a reverse forecast might look sensible, but the CSF payout when both short-priced dogs finish first and second is often disappointingly small relative to your stake.

Before placing any forecast, mentally calculate the cost of the bet structure and ask whether a realistic CSF return — not the dream scenario but the probable range — makes the outlay worthwhile. If the answer is marginal, consider narrowing to a straight forecast on the most likely combination and accepting the binary outcome.

Forecast Strategy — When and How to Use Them

Forecasts reward punters who can read the race shape, not just individual form. A straight win bet requires you to identify the best dog. A forecast requires you to understand how the race will unfold — where the early pace comes from, who gets crowded at the first bend, and which running styles complement each other in a way that produces a predictable finishing order.

The strongest forecast races share certain characteristics. Look for events where the trap draw gives a clear pace advantage to one runner — a fast breaker drawn wide in trap 6 on a track where outside traps dominate, or a strong railer from trap 1 at a venue with a known inside bias. When you can confidently project which dog will lead, the forecasting question simplifies to identifying who finishes best behind it.

Another productive angle is the graded race where one dog has been dropped in class. A dog moving down from A3 to A5 might not be the obvious favourite — the market sometimes undervalues grade drops in greyhound racing because form figures look unimpressive against stronger opposition. But that dog’s finishing speed and consistency often make it an ideal forecast anchor: unlikely to be caught by the rest of the field, and simple to pair with the best of the remaining runners.

Avoid using forecasts as lottery tickets. Some punters will put up four or five dogs in combination forecasts across several races, racking up dozens of bets at small stakes. The hit rate on this approach is abysmal, and the cumulative cost burns through a bankroll faster than it looks. Targeted, single-race forecasts based on a clear thesis about how the race will develop are vastly more effective than scattergun coverage across a meeting card.

One final tactical point: computer straight forecast dividends are based on the starting prices of all runners, not just the two that fill the forecast. A declared non-runner changes the CSF calculation because it removes a runner from the probability model. If there’s a late withdrawal in a race you’ve forecast, the payout may shift — sometimes meaningfully. Keep this in mind when placing forecasts on races where a runner looks doubtful.

The Forecast Mindset — Precision Over Volume

One well-reasoned forecast beats ten hopeful ones. That’s not motivational patter — it’s arithmetic. A punter who places ten combination forecasts at £6 each across a meeting spends £60 and needs at least one dividend above that threshold just to break even. The odds of landing a CFC in any given six-dog race are roughly 1 in 5 for a three-dog combination (since you’re covering 6 of the 30 possible first-and-second permutations). Over ten races, you’d expect to land one or two, but the dividends at typical greyhound odds won’t always cover the accumulated cost.

Contrast that with a punter who studies a full meeting card and identifies one or two races where the shape is clear — where the trap draw, the grading, and the pace profiles point to a high-confidence first and second. A single £5 straight forecast on that race costs a fraction of the scattergun approach and, when it lands, often returns more because the conviction allowed for a stronger selection at a better price.

The forecast mindset is a discipline of restraint. Most greyhound races are not forecastable with any real confidence. Six dogs in a tight field on a fast track can produce almost any finishing order. The skill is recognising the minority of races where the ingredients align: a clear pace advantage, a form differential between the top two and the rest, and a trap draw that doesn’t introduce unnecessary chaos at the first bend.

Track those races, keep records of your forecast reasoning versus the actual outcome, and you’ll start to recognise patterns. Which tracks produce the most forecastable results? Which grades tend to produce the widest gaps between the top two and the rest? Which distance categories sort the field most reliably? The answers vary, but the process of asking the questions is what separates a forecast punter from a forecast gambler.
