Forecast and Tricast Betting in Horse Racing: How to Predict Finishing Order for Bigger Payouts
Available in US
The first tricast I ever cashed was on a Monday afternoon at Pontefract in 2017 — three horses I’d liked in a six-runner handicap, in the right order, paying just over 700/1 from a £2 stake. I came out of the betting shop convinced I’d discovered something. Six weeks later I’d lost roughly twice the original payout chasing similar combinations across the summer and came to the more sober realisation that the bet had paid because the underlying race fell my way, not because I’d cracked some structural pricing inefficiency. The lesson stuck. Forecast and tricast betting is genuinely useful in the right races, genuinely punishing in the wrong ones, and the difference between them is the analytical work that goes in before the bet rather than the size of the dividend.
The structural appeal is obvious. Picking the first two in correct order pays significantly more than picking just the winner; picking the first three pays significantly more still. The structural difficulty is also obvious: predicting finishing order accurately is much harder than predicting winners, and the multiplied returns reflect the multiplied difficulty rather than offering free value. The punters who use forecasts and tricasts profitably do so selectively, applying them only to races where their analytical work supports specific finishing-order predictions.
This article walks through the main forecast structures, the tricast mechanics, the difference between Computer Straight Forecast dividends and fixed-odds versions, and the race types where these bets actually offer value rather than entertainment dressed as edge.
Straight, Reverse and Combination Forecasts Explained
The forecast family covers three related bet types that all predict the first two finishers in a race, with different coverage and different cost.
The straight forecast is the simplest version. You name two horses in a specific order — your selection to win and your selection to finish second. The bet pays only if the race finishes in exactly that order. A single £1 straight forecast on Horse A to win and Horse B to finish second pays a dividend (calculated as Computer Straight Forecast, or CSF) if A wins and B is second, and pays nothing in every other outcome — including if both horses finish in the first two but in the reverse order. The bet is cheap, the payouts can be substantial when the prices are right, and the strike rate is correspondingly low.
The reverse forecast covers both orderings. A £1 reverse forecast on Horses A and B is effectively two straight forecasts — A to win with B second, and B to win with A second. The bet pays the relevant CSF dividend whichever of the two orders the race finishes in, but costs twice as much because two separate forecasts are being placed. Reverse forecasts are the appropriate version when you’re confident the two horses will dominate but unsure which will win.
The combination forecast extends the same logic across three or more selections. A £1 combination forecast on three horses (A, B, C) covers every possible ordering of the three, which is six combinations — AB, BA, AC, CA, BC, CB — costing £6 total. The bet pays the relevant dividend if any two of the named three horses finish first and second, in either order. The cost scales rapidly with the number of selections: four horses produces 12 combinations, five horses 20 combinations. Combination forecasts are useful in races where you can confidently narrow the field to three or four credible horses but can’t predict the specific order.
The structural maths matters. UK favourites win 30 to 35% of races overall, with handicap favourites at about 25.7% and novice favourites at roughly 33%. The probability of a specific two-horse forecast comes from multiplying probabilities. The pricing on these bets reflects rough probabilities of this kind, with the dividend representing what the CSF computer calculates from the SP prices. Punters who can identify forecasts where their own probability assessment is materially higher than the SP-based calculation have a structural edge; those who simply spray combinations are paying the structural cost without the offsetting edge.
Tricast Bets: Picking the First Three in Order
The tricast extends the forecast concept to the first three finishers. The straight tricast names three horses in specific order — winner, second, third — and pays a Computer Tricast (CTC) dividend if the race finishes in exactly that sequence. The combination tricast covers every ordering of the named selections.
The maths gets demanding quickly. With three named horses, a combination tricast covers six orderings of three horses (ABC, ACB, BAC, BCA, CAB, CBA), costing six units. With four horses, the combination expands to 24 orderings. With five horses, 60 orderings. The cost-to-coverage ratio means combination tricasts are typically viable only with very narrow selections — usually three horses, occasionally four in carefully chosen races.
The CTC dividend mechanism produces payouts that often look spectacular relative to the stake. A tricast in a competitive twelve-runner handicap can pay several hundred pounds to a unit stake when the named horses include genuine outsiders. The dividend reflects the difficulty — even when each of the three horses is individually plausible, the probability of any specific finishing order is small, and the payout is the inverse of that probability after the operator margin.
The structural rule for tricasts is selectivity. The bet works only in races where the analytical work supports a confident prediction about the finishing order, which is a much higher bar than confident prediction about the winner alone. The races where tricasts genuinely make sense are typically small-field affairs (six to nine runners) where the form lines clearly identify three dominant contenders, the pace shape supports specific running positions, and the conditions favour the same horses for all three placings. Races meeting all these criteria are rare; the discipline is to wait for them rather than to manufacture tricasts in races that don’t qualify.
The flat racing context matters too. Tricasts on the all-weather circuit produce particularly clean structures in mid-tier handicaps because draw bias and pace tendencies often anchor the running positions tightly. Tricasts in National Hunt races carry additional variance from jumping incidents — even in small fields, fallers and unseats can disrupt the predicted order. The cleanest applications of tricasts tend to concentrate on flat races where the structural complications are fewer.
Computer Straight Forecast vs Fixed-Odds Forecast
The two main ways UK punters can place forecast bets — the Computer Straight Forecast (CSF) and fixed-odds forecasts at individual bookmakers — work differently and produce materially different results across the same selections.
The CSF is a dividend-based bet operated by the Tote across most UK races. The bet pays a dividend calculated by formula from the official starting prices of the first two finishers. The CSF formula factors in field size, the prices of both horses, and the relative strength of the field as a whole. The dividend isn’t fixed in advance; it’s calculated after the race using the SP prices.
The advantage of the CSF is straightforward access to forecast betting across virtually every UK race, with the dividend mechanism producing reasonable payouts in competitive races. The disadvantage is the lack of price transparency before the bet — you don’t know exactly what the forecast will pay until the race is over and the SPs are confirmed.
Fixed-odds forecasts from bookmakers operate differently. The bookmaker publishes specific prices for individual forecast combinations before the race — Horse A to win with Horse B second at, say, 14/1. The punter takes the price and the payout is locked in regardless of how the race develops. Fixed-odds forecasts are available across most UK races and offer the price-transparency advantage at the cost of structurally tighter margins than the CSF computation.
The structural comparison varies race by race. Some races see CSF dividends materially exceed comparable fixed-odds forecasts because the SP prices on the named horses drift in the on-course market. Other races see fixed-odds forecasts beat the eventual CSF dividend because the prices shortened on the day. The discipline for active forecast bettors is to compare both routes for the specific selections under consideration rather than defaulting to one or the other.
The market depth on these bets reflects how UK racing markets price ordered outcomes. Second favourites win about 20% of races, third favourites win 12 to 15%, and the top three favourites combined win 65 to 70% of all races. Most forecasts that pay out involve combinations from this top-three favourite cluster, with longer-priced horses producing the occasional spectacular payouts that distort the apparent value of the bet type. The realistic edge comes from forecasts within the top-three-favourite range where your analytical work points to a specific ordering rather than the random hits at long prices.
Race Types Where Forecasts and Tricasts Offer Value
The races where forecast and tricast betting genuinely make sense share several structural features. Recognising these features is what separates profitable use of these bets from the casual application that quietly leaches money across a season.
Small-field races are the first category. Six- to eight-runner handicaps, particularly on the all-weather, produce racing where the analytical work can credibly identify the first two or three. Big-field handicaps with 16 or 20 runners introduce too much variance — even strong analytical work struggles to predict ordered finishes when the field is that deep.
Races with clear pace shape are the second category. Some races have an obvious front runner who will dominate the early stages, combined with one or two closers whose finishing styles produce predictable late-race patterns. When pace clearly favours specific running positions, the finishing order becomes more predictable.
Races with limited form variance are the third category. UK favourites win 30 to 35% of races but the rate varies — handicaps at 25.7% have more variance and produce more upsets than novice events at 33%. Tricasts in novice flat races, where the most-fancied horses have clearer ability differentials, produce more readable finishing orders than tricasts in big-field handicap sprints.
Conditions-specific races are the fourth category. When the going, distance and course profile all favour the same kind of horse, the pool of credible contenders shrinks to a small subset of the field, and the analytical work can focus on ordering within that subset. Soft-ground handicaps for confirmed Soft-ground specialists, or sprints over tight tracks where draw bias eliminates wide-drawn runners, narrow the credible finishing order before any individual form work begins.
The cadence implication is that profitable forecast and tricast betting concentrates on a small number of carefully chosen races per week. Three to five qualifying races weekly is typical for a disciplined approach. Stakes should be modest because variance is high and losing streaks of fifteen or twenty are plausible. Records need to track strike rate and average dividend separately, because the headline ROI can be distorted by single large payouts.

Building Forecasts into a Wider Strategy
The serious case for forecast and tricast betting isn’t that they’re inherently profitable bet types — they’re not, across casual use — but that they offer specific high-value opportunities in carefully selected races. The punters who profit from them treat them as occasional analytical plays alongside their primary win-and-each-way activity rather than as a primary betting type.
The realistic conclusion is that forecast and tricast betting is a specialist tool. Used selectively in the right races with disciplined stakes, it can produce a meaningful contribution to a UK racing punter’s annual returns. Used carelessly across the broad weekly programme, it quietly drains the bankroll disciplined win-only betting was building.
What is the difference between a forecast and a tricast?
A forecast predicts the first two finishers in a race. A tricast predicts the first three. The straight version of each requires the prediction to be in exactly the right order; the reverse forecast covers both orderings of two horses; the combination forecast or combination tricast covers every ordering of the named selections. Tricasts pay considerably more than forecasts because predicting three finishers in order is much harder than predicting two, but the cost-versus-strike-rate trade-off needs to be evaluated race by race rather than assumed in advance.
Is a combination forecast better value than a straight forecast?
It depends on the race. A combination forecast on three horses costs six unit stakes versus one for the straight forecast, but covers every possible ordering of the named selections. The combination is better value when your analytical work supports three credible contenders but doesn’t confidently rank them; the straight forecast is better value when your work clearly identifies one horse to win and one to finish second. The structural maths means combinations rarely produce stand-out positive expected returns across casual use — they make sense only when the analytical case genuinely supports the wider coverage.
