Two Dogs in Order — or Three, If You Dare
Forecast and tricast bets are high-wire acts — but the payouts justify the height. Where a straight win bet asks you to pick the winner, and each-way asks you to pick a dog that finishes in the top two, forecasts and tricasts demand something harder: predicting the exact finishing order of two or three dogs. Get it right, and the returns can be extraordinary. Get it wrong by a single position, and you lose everything.
In greyhound racing, these bet types occupy a specific niche. The six-dog field makes forecasts and tricasts mathematically tighter than equivalent horse racing bets — there are only 30 possible exact-order pairings in a six-runner forecast and 120 permutations for a tricast. That sounds like a lot, but it’s a fraction of what you’d face in a twelve-runner handicap hurdle. The smaller field means the odds aren’t as long as in horse racing, but the hit rate is meaningfully higher, and for punters who study form, trap draw, and running styles, the edges are real.
Straight vs Reverse Forecast Explained
A straight forecast names first and second in exact order — get it wrong by one place and you lose. You’re selecting dog A to finish first and dog B to finish second. If those two dogs finish in that precise order, the bet wins. If they reverse positions — B first, A second — a straight forecast loses.
The payout on a straight forecast is calculated by the bookmaker using a formula based on the starting prices of both dogs and the number of runners. There’s no fixed odds display before the race in most cases; instead, forecasts are settled at a computer-generated dividend declared after the result. This means you know what you’re trying to predict, but you don’t know exactly what you’ll be paid until the race is over. Typical straight forecast returns in a competitive six-dog Derby heat range from around 15/1 for two well-fancied dogs to 150/1 or more when outsiders fill the first two places.
A reverse forecast removes the order requirement — but doubles your stake. It’s effectively two straight forecasts in one: dog A first and dog B second, plus dog B first and dog A second. If either combination lands, you win. The payout is the straight forecast dividend for whichever order actually occurred, but because you’ve placed two bets, your initial outlay is twice what a straight forecast would cost. A £5 reverse forecast costs £10.
When should you use each? Straight forecasts are for situations where you have a strong view about the winner and a secondary opinion about who’ll chase it home. If you’re confident that a front-running railer from trap one will lead throughout, and you think the dog in trap four has the pace to run into second without troubling the leader, a straight forecast captures that exact scenario at a price.
Reverse forecasts suit races where you’ve identified two dogs that you believe will fill the first two positions but can’t confidently separate them. Derby semi-finals often produce these conditions — two impressive heat winners drawn in the same semi, both with legitimate claims to win, both likely to be involved at the business end. A reverse forecast covers both outcomes and still delivers a meaningful payout.
How Tricasts Work
First, second, third — in order. The odds stack, and so do the potential returns. A tricast takes the forecast concept and extends it by one position, requiring you to name the dogs that finish first, second, and third in exact sequence. In a six-runner greyhound race, that’s picking three from six in the correct order — 120 possible permutations, of which exactly one pays out.
Like forecasts, tricasts are settled at a computer-generated dividend based on the starting prices of all three placed dogs. The returns are substantially higher than forecasts because the additional variable — the third-place finisher — multiplies the difficulty. A tricast involving two mid-priced runners and one outsider in a Derby heat can return anywhere from 200/1 to over 1,000/1 on a £1 stake. Even a tricast featuring three well-fancied dogs often pays 40/1 to 80/1.
The appeal is obvious: small stakes, large potential returns. But the hit rate is low. In a perfectly random six-dog race, the probability of nailing a straight tricast is 1 in 120, or 0.83%. Form analysis can improve those odds — if you genuinely believe three specific dogs will dominate the field, the actual probability might be closer to 3–5% — but you’re still losing the vast majority of your tricast bets. This isn’t a bet type that sustains a long-term staking plan. It’s a targeted play for races where you have unusually high conviction about the first three home.
Derby finals are among the best greyhound racing opportunities for tricasts precisely because the field quality is concentrated. Six dogs that have survived multiple knockout rounds are more likely to finish in a form-based order than six random graded dogs at a midweek open meeting. The Derby final reduces the randomness that makes tricasts unreliable in ordinary racing, and that reduction in noise is where your edge lives.
Combination Bets: Covering More Outcomes
A combination forecast covers all permutations of your selected dogs. Instead of naming an exact finishing order, you pick two, three, or more dogs and let the bet cover every possible way they could fill the relevant positions. The trade-off is cost: more permutations means more individual bets, and your total stake multiplies accordingly.
A combination forecast on three dogs — let’s call them A, B, and C — covers six permutations: A-B, A-C, B-A, B-C, C-A, and C-B. At £1 per permutation, the bet costs £6. If any two of your three dogs finish first and second in any order, one of those six permutations wins, and you receive the straight forecast dividend for that specific finishing order.
Combination tricasts work the same way but with three finishing positions. Selecting three dogs for a combination tricast covers all six possible orderings of those three in first, second, and third. At £1 per line, that’s a £6 stake. Selecting four dogs covers 24 permutations; five dogs covers 60. The costs escalate quickly, and the payout needs to justify the outlay — which it often does when at least one outsider is involved, because that dog’s price inflates the dividend significantly.
The practical question is how many dogs to include. Two-dog combination forecasts are identical to reverse forecasts — there are only two permutations. Three-dog combination forecasts hit a useful balance between coverage and cost, especially in races where you’ve identified a clear top three but can’t rank them internally. Beyond three, the cost begins to erode the value unless you’re specifically targeting a long-priced tricast with a mix of fancied and unfancied selections.
For Derby racing, the three-dog combination forecast is arguably the most underused tool in the punter’s kit. In a six-runner final where form suggests three dogs are a cut above the rest, a £2 combination forecast costs £12 and covers every possible pairing from your shortlist. If two of your three run to expectations, you collect. It’s not cheap, but it’s methodical, and it removes the guesswork of picking an exact order in a race where half a length separates the principals.
Precision Bets for the Prepared Punter
Forecast and tricast aren’t lucky dips — they reward those who’ve done the form work. The entire premise of these bet types is that you know enough about the runners to predict not just who will perform well, but in what order they’ll finish. That’s a high bar, and meeting it consistently requires a deeper level of analysis than picking a winner.
Start with running styles. A front-runner from an inside trap paired with a closer from the outside is a different forecast proposition than two wide runners drawn next to each other. Think about how the race will unfold in the first fifty metres — where will each dog be at the first bend? — and work forward from there. The dogs that get clear early tend to hold position in greyhound racing far more reliably than in horse racing, which makes trap draw and early pace the two most important variables in your forecast analysis.
The Greyhound Derby, with its knockout format and six-dog finals, is one of the best opportunities in the sport for intelligent forecast and tricast betting. You’ve had weeks of round-by-round evidence to assess each dog’s preferred position, reaction to crowding, and response to different draws. By the time the final arrives, you know more about these six dogs than you’ll ever know about a random Tuesday-night field. Use that information. The payouts on Derby forecasts and tricasts are generous enough to reward even a modest analytical edge — and in a race where favourites lose more often than they win, getting the order right can be worth considerably more than simply backing the winner.
