Greyhound Forecast Betting Explained

What Is a Forecast Bet in Greyhound Racing?

Pick the first two in the correct order — or pay for both permutations. That is the forecast bet reduced to its essentials, and in greyhound racing it is one of the most popular wagers after the standard win and each-way markets. A forecast requires you to name which dog will finish first and which will finish second, in exactly that order. Get both right and you collect a dividend that typically exceeds anything a single win bet would have returned. Get either position wrong and you lose.

In a standard six-runner greyhound race, there are 30 possible forecast combinations — six dogs that could win, each paired with five possible second-place finishers. That means a single straight forecast has a roughly 1-in-30 chance of landing if all dogs were equally matched, though in reality the probabilities are weighted by each dog’s actual ability. The appeal of forecast betting is that it leverages your ability to read not just the likely winner but the shape of the entire race: who leads, who chases, and who fades.

There are two primary forms of forecast bet. A straight forecast names the first and second in a fixed order — Dog A to win, Dog B second. A reverse forecast covers both permutations: Dog A first and Dog B second, or Dog B first and Dog A second. The reverse forecast is technically two bets, so a £1 reverse forecast costs £2. Most bookmakers also offer combination forecasts, which allow you to select three or more dogs and cover every possible first-second pairing among them. Select three dogs and you have six permutations, costing six times your unit stake. Select four and you have twelve permutations.

Forecast bets in greyhound racing are settled either at a declared forecast price offered by the bookmaker before the race, or via the Computer Straight Forecast dividend calculated after the race. The settlement method depends on where and how you place the bet. At the track, tote forecast bets are settled from the forecast pool. Online, most bookmakers offer their own forecast odds or settle at the industry CSF. The distinction matters because the payout can differ significantly depending on the method — a point explored in detail below.

The structural reason forecasts appeal to greyhound punters specifically, rather than to horse racing punters exclusively, is field size. Six runners produce a manageable number of combinations. Picking the first two in a 20-runner horse race is a different challenge entirely — the permutations multiply and the strike rate plummets. In greyhound racing, a well-read punter who correctly identifies the two strongest dogs in a race has a realistic shot at landing a forecast. That realistic strike rate, combined with returns that often outstrip a simple win bet by a factor of three or four, makes forecasts a core part of the greyhound betting toolkit.

Straight vs Reverse Forecast: Costs and Returns

A reverse forecast doubles your stake but covers both finishing orders. Whether that doubling is justified depends on how confident you are about which of your two selections will win and which will place.

Consider a race where you fancy Trap 1 and Trap 4. If you believe Trap 1 is clearly the stronger and Trap 4 is a solid each-way proposition, the straight forecast — Trap 1 first, Trap 4 second — makes sense. You are backing your strongest conviction in the correct order and keeping your stake at one unit. If, however, you think both dogs are closely matched and either could lead, the reverse forecast covers you for both outcomes at the cost of two units. The question is whether the race dynamics support a strong order preference or not.

Returns on straight forecasts in greyhound racing vary enormously. A forecast involving a short-priced favourite finishing first and the second favourite finishing second might return as little as 3/1 or 4/1. A forecast with two outsiders finishing first and second can return 100/1 or more. The dividend is a function of the individual prices of both dogs, with a correlation adjustment applied. This is why forecast returns are not simply the multiplication of two win odds — the CSF formula accounts for the relationship between the runners’ chances, not just their independent probabilities.

For reverse forecasts, the payout is whichever of the two permutations lands, divided by two because you have placed two bets. If the forecast dividend for Trap 1 first and Trap 4 second would have been £30, but the actual result is Trap 4 first and Trap 1 second with a dividend of £45, you collect £45 minus your second losing unit. Your net return is the winning dividend minus the total stake of two units. The maths is straightforward; the discipline lies in recognising when you are paying double for insurance you do not need.

In practice, experienced forecast punters use straight forecasts when they have a clear view on the likely winner and reverse forecasts when two dogs are genuinely inseparable. They avoid combination forecasts with four or more dogs in most circumstances, because the cost of covering twelve or more permutations erodes the return-on-investment even when the forecast lands. Three-dog combinations, at six units, sit at the boundary — acceptable when the race is competitive and at least one outsider is included, because the potential dividend on an outsider finishing in the first two can justify the extended coverage.

CSF Dividends: How Computer Straight Forecast Payouts Are Calculated

The Computer Straight Forecast is not set by a bookmaker. It is a formula applied after the race, using the returned Starting Prices of all runners to generate a theoretical fair dividend for every possible first-second combination. The industry algorithm takes the win odds of the first-place dog, the win odds of the second-place dog, and the odds of every other runner in the field, then calculates what a forecast paying fair market prices would return.

The calculation is not something most punters need to replicate by hand — it involves converting all SPs to implied probabilities, applying combinatorial adjustments, and factoring in the overround. What matters practically is understanding what the CSF represents: a standardised, post-race dividend that applies regardless of which bookmaker you placed your bet with. If you bet a straight forecast online and your bookmaker settles at the CSF, you receive the same dividend as any other punter who backed the same combination at any other CSF-settling operator.

The CSF tends to produce returns that are broadly proportional to the difficulty of the forecast. Two favourites filling the first two positions returns a modest CSF — often in single figures. A favourite winning with an outsider in second returns a mid-range CSF, perhaps 15/1 to 30/1. Two outsiders filling the places can produce CSFs well into three figures. The formula rewards unlikely outcomes more generously, which is precisely what makes forecast betting attractive to punters who are willing to take a view against the market.

One point that catches punters off guard: the CSF can differ from a bookmaker’s own declared forecast price, sometimes significantly. Some bookmakers offer forecast prices before the race as a fixed-odds alternative to the CSF. These declared prices are set by the bookmaker’s own traders and may be more or less generous than the CSF would turn out to be. If you are offered a declared forecast price that you believe exceeds the likely CSF, taking it locks in the value. If you suspect the CSF will be higher — typically in races where outsiders have a realistic chance of placing — leaving the bet to settle at the CSF may be the better play.

At the tote, forecast dividends are calculated differently again. The tote forecast pool takes all money staked on forecast combinations, deducts a percentage, and divides the remainder among winning tickets. Tote forecast dividends can vary wildly from the CSF, particularly in races with small pool sizes — which is common at greyhound meetings. A tote forecast on an unfancied combination in a low-turnover race can return dramatically more than the CSF equivalent, because the pool was not heavily bet and the few winning tickets share a disproportionate payout.

Forecasts as a Value Play: When the Dividend Beats the Market

The biggest forecast returns come from races where the market underrates the second dog. This is the structural insight that separates forecast punters who grind out long-term profit from those who treat forecasts as lottery tickets.

The logic works like this. In most greyhound races, the market focuses its attention on identifying the winner. The favourite is scrutinised, the second favourite is considered, and the rest of the field receives diminishing analysis from the betting public. The win market is, as a result, reasonably efficient for the front of the market and less efficient for the back of it. Forecast betting exploits this asymmetry. If you can identify a dog that the market has priced at 8/1 or 10/1 but whose true chance of finishing second is better than those odds imply, pairing that dog in a forecast with a more fancied runner produces a dividend that exceeds the fair price of the combination.

In practice, this means looking for dogs with strong late pace — runners who may not lead but who consistently finish in the first two or three. These dogs are often underrated in the win market because they do not win often enough to attract attention. But for forecast purposes, a dog that finishes second in four out of ten races is extremely useful. Its win price is long, which inflates the forecast dividend, while its actual probability of filling the second slot is higher than the market suggests.

Another value angle is trap draw. A dog drawn in Trap 1 at a track with a strong rail bias is more likely to lead and hold on than the general market price might reflect. Pairing that dog as the winner in a forecast with a strong finisher drawn wide can produce combinations the market has not fully priced in, because the win market treats each dog independently while the forecast requires you to think about race dynamics — who leads, who chases, who is blocked.

Forecast betting is not for every race and not for every punter. The strike rate is inherently lower than win betting — you need two things to go right instead of one. But when the dividend is there, when the second dog is genuinely underpriced, the forecast is not a gamble. It is a structured bet with identifiable value, built on the same form analysis that underpins any good greyhound selection — extended to the question of who finishes where.
