Greyhound Forecast and Tricast Bets Explained With Harlow Payout Data

The first forecast bet I ever placed at Harlow returned enough to cover a week’s petrol. It was a Monday evening card, two dogs that I rated clearly above the field, and the payout reflected the fact that most punters had backed them separately rather than together. That experience taught me something fundamental about forecast and tricast markets: they reward opinion that goes deeper than picking a single winner. If you can rank the first two or three dogs in the correct order, the returns are substantially larger than anything a straight win bet can deliver – and at a track like Harlow, where graded races often produce predictable pace scenarios, that ranking exercise is more achievable than most people assume.

This piece explains how forecast and tricast bets work, how the computer calculates payouts, and what typical returns look like at Harlow meetings. If you are already placing these bets, the section on typical payouts might sharpen your expectations. If you have never tried them, this is where you start.

What Is a Forecast Bet?

A forecast bet asks you to predict the first and second finishers in the correct order. You are not just picking a winner – you are saying “this dog finishes first and that dog finishes second.” The bet loses if either dog fails to finish in its predicted position, even if both dogs finish in the top two but in the wrong order.

At Harlow, where the favourite wins approximately 36% of the time in graded races, a forecast adds a significant layer of complexity. You need the favourite to win (if you have backed it to do so) and a specific second dog to follow it home. That second prediction is where the value lies, because the second-place market is far less liquid than the win market and bookmaker pricing is less efficient.

The straight forecast is the basic form: Dog A first, Dog B second. You nominate both positions and the bet is settled only if the result matches exactly. Forecasts are available on all GBGB-licensed races at Harlow through on-course tote pools and with all major bookmakers, and the payout is determined either by the tote pool dividend or by the computer straight forecast calculation.

The computer straight forecast – abbreviated CSF – is the mechanism most bookmakers use to settle forecast bets. It is a formula that calculates the payout based on the starting prices of the first two finishers, adjusted for the number of runners and the race conditions. The CSF is not a fixed odds price that you lock in before the race; it is calculated after the result is known, which means the return depends on how the market priced the first two dogs. A forecast combining two short-priced favourites produces a modest CSF. A forecast pairing a mid-priced winner with an outsider in second delivers a much larger return.

One thing I have learned from years of placing forecasts at Harlow is that graded races with six evenly matched runners tend to produce higher CSF returns than races with one dominant favourite. When the market spreads its money across the field, the second-place component of the CSF inflates the return. Conversely, in a race where one dog is odds-on and the rest are 8/1 or longer, the forecast return is often disappointing even if you get the order right, because the overwhelming favourite depresses the first-place component of the calculation.

What Is a Tricast Bet?

A tricast extends the forecast concept to the first three finishers in exact order. Dog A first, Dog B second, Dog C third – all three positions must be correct for the bet to pay. The difficulty is obvious: predicting a winner is hard enough, predicting first and second harder still, and getting all three positions right demands either deep form knowledge or a healthy dose of luck.

The returns compensate for the difficulty. Tricast dividends at Harlow routinely reach double or triple figures, and I have seen payouts exceed four figures on cards where an outsider slipped into third behind two fancied dogs. The tricast is calculated using the computer tricast formula, which works on the same principle as the CSF but extends to three runners. The starting prices of all three finishers, their positions, and the field size all feed into the calculation.

Tricasts at Harlow make the most sense in races where you have a strong view on the first two finishers but consider the third position more open. In that scenario, you are leveraging your forecast opinion and adding a third leg that, if it lands, multiplies the return significantly. The risk is that even one dog finishing out of position voids the entire bet – there is no consolation payout for getting two out of three right.

The UK average favourite win rate in graded greyhound racing sits around 32-35%, which means favourites lose roughly two-thirds of the time. At Harlow, that figure is slightly higher at around 36%, but the point stands: the second and third finishers in any race are statistically difficult to predict, and the tricast market prices that difficulty in. If you have the analytical edge to consistently identify placed runners, the tricast is where that edge pays best.

Reverse Forecasts and Combination Tricasts

I once missed a forecast by a head-bob – my first pick won, my second pick finished third, and the dog I had dismissed came second. That result would have been covered by a reverse forecast, and the experience convinced me that the reverse format deserves a permanent place in any greyhound betting strategy.

A reverse forecast covers both possible finishing orders for two nominated dogs. If you select Dog A and Dog B, the reverse forecast pays if A finishes first and B second or if B finishes first and A second. The stake is doubled because you are effectively placing two straight forecasts, but the coverage is significantly broader. At Harlow, where six-dog fields and tight finishes are common, a reverse forecast captures value in races where you are confident about which two dogs will fill the first two positions but less certain about the exact order.

A combination tricast applies the same logic to three nominated dogs. Instead of predicting the exact 1-2-3 order, you cover all six possible permutations of three dogs filling the first three positions. The stake is six times a single tricast unit because there are six possible orderings. Combination tricasts are more expensive than straight tricasts but far more forgiving, and in races where three dogs stand out clearly from the rest of the field, they offer a pragmatic way to capture the tricast dividend without needing to nail the exact sequence.

The trade-off with both formats is straightforward: broader coverage costs more per race. A reverse forecast at a 2-pound unit stake costs 4 pounds. A combination tricast at the same unit costs 12 pounds. The question you need to answer before placing either bet is whether your form analysis is strong enough on the “which dogs” dimension to justify the cost, even if your “which order” confidence is lower. In my experience, combination tricasts work best in lower-grade Harlow races where three dogs are clearly superior to the remaining three, while reverse forecasts suit mid-grade races with two standout contenders.

Typical Forecast and Tricast Returns at Harlow

Expectations matter. I have watched punters walk away from the window frustrated by a forecast return of 8 pounds on a 2-pound stake, assuming the bet should have paid more. The issue is not the bet – it is the expectation. Forecast and tricast returns vary enormously depending on the prices of the finishers, and knowing the typical range at Harlow helps calibrate realistic targets.

For straight forecasts at Harlow graded meetings, the CSF return on a 1-pound stake typically falls between 5 and 30 pounds. At the low end – a fancied favourite winning with the second favourite in second – you might see a CSF of 4 to 7 pounds. At the upper end, a mid-priced winner followed by a bigger-priced second produces returns in the 20-40 range. The occasional forecast combining an outsider winner with another unfancied dog in second can return over 100 pounds, but these are rare and unpredictable by nature.

Tricast returns start higher. A typical graded tricast at Harlow pays between 20 and 150 pounds to a 1-pound stake, depending on the prices of the first three finishers. A result where all three finishers were among the top four in the betting might return 15-30 pounds. A result involving one outsider in the first three pushes the tricast into triple figures, and when two outsiders fill placed positions the dividend can exceed 500 pounds – though backing that outcome deliberately is more lottery than analysis.

The practical takeaway is this: forecasts and tricasts at Harlow offer the best value in competitive races where the field is closely matched. These races produce higher dividends because the market cannot confidently separate the runners, and the CSF and tricast calculations amplify that uncertainty into larger payouts. Races with a dominant favourite and five no-hopers produce the opposite effect – low dividends that rarely justify the risk of needing two or three dogs in exact positions.
