Best Greyhound Betting Sites – Bet on Greyhounds in 2026

Forecasts reward precision, and in six-dog fields, that precision is more reachable than in horse racing. A straight forecast in a six-runner greyhound race has thirty possible permutations — the number of ways two dogs can finish first and second in a specific order. In a twelve-runner horse race, that number jumps to one hundred and thirty-two. The smaller field size in greyhound racing makes forecast betting not just viable but central to how serious punters approach the sport.
While win bets remain the most popular market, forecasts offer the kind of returns that make a single race worth studying properly. A successful straight forecast on two mid-priced dogs can pay more than an accumulator on three favourites, with the advantage of depending on a single race rather than a chain of events. The trade-off is straightforward: you need to identify two dogs and their finishing order, not just one winner.
This guide covers the three forecast variants available in UK greyhound racing — straight, reverse, and combination — explains how dividends are calculated, and lays out the strategic considerations that separate a speculative punt from a reasoned forecast bet.
The Straight Forecast and CSF
Pick the first and second in order — that is the straight forecast in its simplest form. You select the dog you believe will win the race and the dog you believe will finish second, in that exact sequence. If those two dogs cross the line in the positions you predicted, the bet pays out. Any other finishing order, including a reversal of your two picks, and the bet loses.
The payout on a straight forecast in greyhound racing is not based on fixed odds offered by the bookmaker before the race. Instead, it is determined after the race by a formula known as the Computer Straight Forecast, or CSF. This system takes the starting prices of all six runners into account — not just the two you selected — and calculates a dividend per unit stake. The dividend is declared alongside the result and typically displayed on the bookmaker’s results page within minutes of the race finishing.
The CSF formula is deliberately complex, but the key factors that drive the payout are intuitive enough. Larger dividends result when the first and second finishers are both at longer odds — two outsiders filling the first two positions produces a much bigger return than the favourite beating the second favourite. The overall shape of the market also matters: in a race where one dog is very short and the rest are loosely priced, a forecast involving the favourite and a mid-price runner will pay less than in a race where four dogs are similarly priced.
As a rough guide, a straight forecast with the favourite (say, 2/1) finishing first and a 5/1 shot finishing second might return somewhere between twelve and eighteen pounds to a one-pound stake. Reverse the order — the 5/1 shot winning with the favourite in second — and the dividend climbs, often significantly. Replace the favourite with another mid-price runner in second and the numbers jump again. CSF dividends in greyhound racing regularly exceed fifty or sixty pounds to the unit, and occasionally reach into triple figures when two outsiders fill the frame.
One important detail: the CSF only applies when the race has three or more finishers. If non-runners reduce the field to fewer than three, forecast bets are typically voided. Always check your bookmaker’s rules on non-runners and reduced fields, because the terms vary between operators.
Some bookmakers also offer fixed-odds forecasts on selected greyhound races, particularly high-profile events. These give you a locked-in price before the race starts, which can be advantageous if you believe the CSF dividend will be lower than the fixed price offered. For most graded races and BAGS meetings, however, forecasts settle via the CSF.
Reverse Forecast — Coverage vs Cost
Doubling your stake to cover both orders is the essence of a reverse forecast. Instead of predicting which of your two selections finishes first and which finishes second, you back both permutations: Dog A first with Dog B second, and Dog B first with Dog A second. Because it covers two bets, a reverse forecast costs twice the unit stake — a one-pound reverse forecast is a two-pound outlay.
The appeal is obvious. In a tightly contested race, especially one where two strong dogs are drawn on the same side of the track, predicting which will edge ahead at the line is often a coin toss. The reverse forecast removes that uncertainty. As long as your two selections finish first and second, in either order, you collect.
The return, however, is not simply the CSF dividend. When a reverse forecast lands, you are paid the CSF dividend for the actual finishing order of the two dogs. You do not receive dividends for both permutations — only the one that occurred. So if Dog A wins and Dog B places, you receive the CSF for that specific combination, from a total stake of two pounds. The dividend for the winning permutation must therefore be large enough to exceed your doubled stake for the bet to be profitable.
When does the reverse forecast make strategic sense? Primarily in races where you have a strong read on the front two but cannot separate them. This often occurs when two dogs have similar early pace and are drawn in adjacent traps, meaning they are likely to race alongside each other through the first bend. It also works when one dog is a confirmed front-runner and another is a proven closer — you expect them both in the frame but cannot be sure which prevails.
Where the reverse forecast falls down is when the CSF dividend for one permutation is significantly larger than the other. If Dog A at 6/1 beats Dog B at 2/1, the CSF might pay forty-five pounds. But if Dog B at 2/1 beats Dog A at 6/1, the CSF might only pay fifteen pounds. In the second scenario, your two-pound outlay yields a net profit of just thirteen pounds, which is less than you might have earned from a straight forecast on the right permutation at one pound. This is why experienced punters sometimes place separate straight forecasts at different stakes rather than a single reverse forecast — weighting the more likely permutation more heavily.
Combination Forecast
Pick three or more dogs and cover every possible first-two combination. That is the combination forecast, and it scales quickly. With three selections, you are covering six possible permutations (three dogs multiplied by two possible orders for each pair). With four selections, the number jumps to twelve. Each permutation is a separate bet at your unit stake, so a one-pound combination forecast on three dogs costs six pounds, and on four dogs costs twelve pounds.
The combination forecast is best understood as a broader net. You might look at a six-dog field and identify three contenders who you believe will fill the first two places, but you have no strong opinion on which specific pair or which order. Rather than placing three separate reverse forecasts (which would also cost six pounds for three selections), a combination forecast covers the same ground in a single bet slip.
Returns are calculated the same way as a straight forecast — the CSF dividend for the actual finishing pair in their actual order, paid on the one winning permutation out of your six. The remaining five bets lose. For the combination forecast to be profitable overall, the CSF dividend on the winning permutation must exceed six pounds (or twelve, or whatever the total cost of your combination).
Combination forecasts tend to be most effective in open races or competitive graded events where form analysis narrows the likely front pair to three dogs but does not separate them further. They are less effective in races with a dominant favourite, because including that favourite in a combination forecast guarantees you are covering several permutations where the payout will be modest. In those cases, a straight forecast pairing the favourite with a longer-priced selection is usually the sharper play.
A practical note: combination forecasts can also be placed as “any to come” bets on some platforms, where the returns from one winning permutation roll into subsequent bets. This structure is less common in greyhound racing than in horse racing but is worth understanding if your bookmaker offers it.
Forecast Strategy for Greyhounds
The ideal forecast pairs a likely leader with a strong closer. This is not a universal rule, but it holds true in the majority of four-bend graded races, which make up the bulk of UK greyhound cards. The dog with the fastest early sectional time has a statistical advantage in reaching the first bend ahead of the field, and sectional data gives you a way to identify that dog. The closer is typically a dog with strong finishing pace — one whose form shows it gaining positions in the final straight of recent races.
Start by identifying the probable leader. Compare first-sectional times across the six runners, adjusting for trap draw. A dog with the fastest split but drawn in trap six faces a longer run to the first bend than the same dog would from trap one, which may neutralise the speed advantage. Conversely, a moderate early-pace dog in trap one can sometimes reach the bend first simply by running the shortest distance.
Then look for the dog most likely to finish second. This is often a dog with a strong overall calculated time but a slower first sectional — it starts behind the pace but closes through the field. Form comments like “FinFst” (finished fast) or “RnOn” (ran on) are indicators. Dogs that regularly finish second or third from off the pace are prime candidates for the second slot in your forecast.
Avoid forecasting two confirmed front-runners in a race where they are drawn side by side. When two early-pace dogs are in adjacent traps, they often interfere with each other at the first bend, allowing a third dog to exploit the gap. That interference is the enemy of a neat forecast — it introduces a random element that your analysis cannot control.
Finally, price matters. Forecast dividends scale with the odds of the runners involved. A forecast involving two short-priced dogs rarely pays well enough to justify the effort. The sweet spot is a favourite or second-favourite paired with a 4/1 to 8/1 selection whose form supports a place finish. That combination gives you a realistic outcome with a meaningful return.
Two Dogs, One Question
A forecast is a statement of conviction about the front two. Not a guess, not a cover-all, but a directed opinion backed by form analysis. The straight forecast demands the most precision and offers the highest reward. The reverse and combination variants broaden the net at the cost of return per unit staked.
The question you need to answer before placing any forecast bet is simple: can I identify the most likely pair? If you can narrow the probable first two down to specific dogs — not just “one of these four” — a straight or reverse forecast is the market to use. If your analysis only gets you to a shortlist of three, the combination forecast gives you coverage without abandoning the forecast market entirely.
In greyhound racing, with six runners and no jockey decisions to add randomness, the front two are more predictable than in most other racing formats. That is what makes forecasts the natural market for punters who do their homework.
