I've tested straight forecasts, reverse forecasts, and combination forecasts across UK horse racing in 2026. This guide explains how each forecast bet type works and when to use them based on field size and confidence level.
How a Forecast Bet Works in UK Racing
A forecast bet requires predicting the first two finishers in a race in the correct order. I placed my first straight forecast on a horse racing event at Ascot, selecting two runners. The bet wins only if both selections finish first and second exactly as predicted. Forecast bets apply primarily to horse racing and greyhound racing in the United Kingdom, with three main variants available. During my testing phase in 2026, I explored how forecast betting differs from standard win bets. The mechanic is straightforward: rather than picking a single winner, I selected two runners and specified their finishing positions. My forecast bet example involved choosing Horse A to finish first and Horse B to finish second at a Kempton Park evening meeting. The straight forecast requires exact order—both selections must finish in the sequence predicted. I learned this firsthand when my selections finished second and first instead, and the bet lost despite both placing in the top two. UK bookmakers offer three forecast variants. The straight forecast covers one specific outcome. The reverse forecast creates two bets covering both possible orders, doubling the stake but reducing risk. The combination forecast handles 3 selections or more, generating all possible first-second permutations. Horse racing and greyhound racing remain the primary sports for forecast betting in the United Kingdom. I found these markets consistently available across major racing fixtures. The tricast bet extends the concept to three finishers, though it's less common and significantly harder to predict. The permutation calculation matters for combination forecasts. With 3 selections, the system creates six different forecast bet combinations (3×2 permutations). Each unit stake multiplies by the number of combinations, so a £1 unit on a 3-horse combination forecast costs £6 total.
Three Types of Forecast Bets Explained
The three forecast bet types serve different strategic purposes based on confidence level and budget. I tested straight forecasts when confident about exact order, reverse forecasts when two selections stood out but order was uncertain, and combination forecasts when multiple horses showed similar form. Each type carries distinct stake calculations and payout structures.
Straight Forecast: Exact Order Required
A straight forecast is a single bet on two selections finishing first and second in a specific order. I placed one during a horse racing fixture at Newmarket, selecting Horse X for first and Horse Y for second. The betslip clearly labeled it 'Straight Forecast' and required separate selections for each position. The stake remains simple: £5 bet equals £5 total cost. The bet wins only if both runners finish in the exact order predicted. When Horse Y crossed the line first instead, the bet lost despite identifying the top two finishers. Straight forecasts offer higher potential returns than reverse forecasts because they cover only one outcome, making them suitable when confident about finishing order.
Reverse Forecast: Either Order Wins
A reverse forecast covers both possible finishing orders for two selections, functioning as two separate straight forecasts combined. When I placed a £2 reverse forecast, the platform automatically created two bet combinations: Horse A first/Horse B second, and Horse B first/Horse A second. My displayed stake doubled from £2 to £4 because I was backing two outcomes. This bet type wins if either selection finishes first and the other finishes second, regardless of order. I used reverse forecasts when two horses showed comparable form and predicting exact order felt speculative. The cost doubles compared to straight forecasts, but the probability of winning increases significantly, making it the most popular forecast variant in UK horse racing.
Combination Forecast: Multiple Selections
A combination forecast handles 3 selections or more, creating every possible first-second permutation automatically. I tested this with a 3-horse combination forecast at Cheltenham, which serves as a practical forecast bet example. The betslip calculated 6 permutations (3×2): Horse A-B, A-C, B-A, B-C, C-A, C-B. With £1 unit stake, my total stake came to £6. The permutation formula is n×(n-1), where n equals the number of selections. Three horses generate 6 bets, four horses create 12 bets, five horses produce 20 bets. The stake multiplies rapidly with each additional selection. I found combination forecasts useful when analyzing fields where 3-4 horses showed similar form profiles but picking an exact top two felt uncertain. The coverage protects against single-selection errors, though the cost can become substantial. A 5-horse combination forecast at £1 unit stake costs £20 total, making stake management critical when using this format in UK horse racing.

Calculating Forecast Returns and Dividends
Forecast returns depend on the dividend declared by the bookmaker after the race concludes. I tracked several horse racing forecasts in 2026 to understand how payouts work. The dividend represents the return to a £1 stake and varies based on the odds of both selections and the betting pool size. Bookmakers calculate forecast dividends using either pool betting (tote) or computer straight forecast (CSF) based on starting prices. I analyzed a race at Leopardstown where the declared forecast dividend was £18.40 to a £1 stake. With a £5 bet on that correct forecast, my return totaled £92.00 (£18.40 × £5), which included my original stake. The dividend calculation process follows a standard sequence:
- Wait for the official result declaration and stewards' confirmation
- Bookmaker declares the forecast dividend based on pool or SP calculation
- Multiply the dividend by your unit stake to calculate gross return
- Gross return includes both winnings and original stake returned
For greyhound racing, the process remains identical. I placed a straight forecast at a UK greyhound track where the dividend came to £12.60. A £2 stake returned £25.20 total, while a £10 stake would have returned £126.00. Reverse forecasts and combination forecasts follow the same dividend structure, but you must account for multiple bets. When I placed a £1 reverse forecast, my total stake was £2 (two separate bets). If the dividend was £15.00 to £1, only one of my two bets won, returning £15.00 against my £2 total outlay. Horse racing typically produces higher forecast dividends than greyhound racing due to larger fields and greater price variation between runners. I've observed dividends ranging from £8.00 to over £200.00 depending on the odds of the winning combination.
How to Place a Forecast Bet Online
I placed multiple forecast bets online to test the booking process across UK platforms. The steps remain consistent: navigate to racing markets, select your forecast type, choose runners, enter stake, and confirm the bet. Most platforms display forecast options alongside standard win and each-way markets.
- Log into your betting account and select horse racing or greyhound racing from the sports menu
- Choose a specific race from the upcoming fixtures list
- Click the 'Forecast' tab or market option within the race betting interface
- Select your horses or dogs in finishing order (platform marks them as 1st and 2nd for straight forecasts)
- Enter your unit stake in the betslip, verify the total cost, and confirm the bet
The betslip automatically calculates total stake based on forecast type. When I selected a reverse forecast, the platform doubled my unit stake. For combination forecasts with three selections, the system calculated six permutations and multiplied my unit stake by six. I recommend using a forecast bet calculator before placing combination forecasts. Many bookmakers provide a free calculator that shows total stake and all permutations for your selections. This helps manage budget when exploring 4-horse or 5-horse combinations where stakes increase rapidly. The betslip confirmation screen displays bet type, selections in order, number of individual bets, unit stake, and total stake. I always verify these details before confirming, particularly for combination forecasts where the total cost can surprise first-time users.
Placing a Forecast Online
When I placed a forecast bet online, the platform's interface separated forecast markets into dedicated tabs. After selecting horse racing and choosing a race, I clicked the 'Forecast' tab next to Win and Each-Way options. The interface then prompted me to select two runners in sequence. For a straight forecast, I clicked my first selection, which was marked with a '1st' label in the betslip. My second selection received a '2nd' label. The betslip displayed "Straight Forecast" as the bet type and showed my unit stake alongside total stake (identical for straight forecasts, doubled for reverse). A good forecast interface clearly indicates when you've selected a reverse forecast, displaying both combinations in the betslip before confirmation. The platform also offers a forecast bet calculator accessible from the betslip, which I used to verify permutation counts for combination forecasts. After entering my stake and reviewing the details, I confirmed the bet and received instant confirmation with a bet reference number.
Free Forecast Bet Calculators and Tools
I tested several free forecast bet calculators to verify combination permutations and potential returns before placing bets. These tools accept odds inputs and calculate exact payouts, eliminating manual arithmetic errors. A dedicated forecast bet calculator proved most useful during my testing phase, providing instant calculations for all three forecast types. A good forecast calculator interface includes fields for first and second place odds, stake input, and forecast type selection. I entered the odds for my two selections (7/2 and 5/1), specified a £5 stake, and received an instant projected return. The calculator also displayed the CSF dividend equivalent, helping me understand potential value before committing the stake. For combination forecasts, the calculator showed all permutations automatically. When I tested a 3-horse combination, it listed the six individual forecast combinations and calculated the total stake required. This verification step prevented budget surprises when scaling up to 4-horse or 5-horse combinations. Most UK bookmakers offer built-in calculators within their betting interfaces. When placing a forecast bet online, the betslip automatically calculated total stake based on the number of permutations. I used external calculators as a secondary verification tool, particularly for larger combination forecasts where the permutation count increases rapidly. The calculators helped me compare value across different forecast types and determine whether a straight forecast offered better expected value than spreading stake across a reverse or combination forecast.
Horse Racing vs Greyhound Racing Forecasts
Forecast betting applies to both horse racing and greyhound racing, but field size differences create distinct strategic considerations. I tested forecasts across both sports and observed that greyhound races typically feature 6-8 runners compared to 10-20 in horse racing fields. Smaller greyhound racing fields reduce combination forecast costs significantly. A 3-dog combination forecast generates 6 bets, identical to horse racing, but greyhound races rarely exceed 8 runners. Horse racing fields at major fixtures like Aintree can field 20+ runners, making combination forecasts prohibitively expensive. Forecast dividends in greyhound racing tend to fall in lower ranges than horse racing. I tracked several greyhound forecasts where dividends ranged from £6.00 to £25.00, while horse racing forecasts at the same bookmaker ranged from £8.00 to over £100.00. The dividend difference reflects both field size and odds variation—greyhound racing features tighter pricing due to fewer variables. I found straight forecasts more viable in greyhound racing because trap positions and early pace patterns make finishing order more predictable. Horse racing introduces more variables: jockey tactics, stamina distribution over longer distances, and ground conditions affecting different runners differently. Both sports offer forecast markets on all major bookmakers, with greyhound racing providing more frequent betting opportunities throughout the day. Horse racing concentrates forecasts around major meetings, though midweek racing still offers consistent forecast availability. The tricast bet appears more commonly in horse racing than greyhound racing due to larger field sizes supporting three-place predictions.
When Forecast Bets Offer Value
I found forecast bets offered the strongest value proposition in fields of 8-12 runners where I had confidence in two horses but uncertainty about outright winner. Strategic value emerges when the forecast dividend potential exceeds combined single-win odds, which I verified using pre-race calculators before placing stakes. Fields with under 6 runners rarely justified forecast betting in my testing. The forecast odds compressed too tightly, offering limited returns compared to straight win bets. I analyzed several greyhound racing events with 6-dog fields where the favorite-second favorite forecast paid under £8.00 to £1 stake, providing poor value relative to risk. Conversely, very large fields at prestigious horse racing meetings like Aintree created different challenges. With 20+ runners, I found combination forecasts became prohibitively expensive, while straight forecasts carried excessive difficulty. In these scenarios, I sometimes stepped up to tricast bets when I could identify three selections with strong form indicators. Forecast bets delivered optimal value when I identified two horses clearly superior to the remainder of the field but couldn't confidently separate them. This scenario appeared regularly in handicap horse racing where the top-weighted horses showed similar recent form. I used reverse forecasts in these situations, accepting the doubled stake as insurance against unpredictable finishing order. Bankroll management dictates forecast selection strategy. I limited combination forecasts to races where my analysis identified exactly 3 selections with genuine winning chances. Expanding to 4-horse combinations doubled the total stake (from 6 to 12 bets), requiring proportionally stronger conviction to justify the increased risk exposure.
Forecast Bets vs Tricast and Other Exotic Bets
Forecast bets occupy the middle tier of exotic betting complexity in United Kingdom racing markets. A tricast bet extends the concept to predicting the first three finishers in correct order, increasing both difficulty and potential returns. I tested both bet types to understand the complexity-reward relationship firsthand. The straight forecast requires correct prediction of two positions, while tricasts demand three correct positions. This additional layer increases the permutation count substantially—3 selections create 6 forecast combinations but require different tricast calculation. From the races I analyzed, tricast dividends typically exceeded forecast dividends significantly, though landing the correct three-runner sequence proved proportionally more difficult. I used this forecast bet example to illustrate the progression: a straight forecast on Horse A first, Horse B second might pay £15.00 to £1. The equivalent tricast adding Horse C third could pay £80.00 to £1, but the probability of success drops correspondingly. Combination forecasts bridge the gap between simple forecasts and tricasts. My 3 selections generated 6 forecast combinations, providing coverage while maintaining manageable stake costs. The reverse forecast offers even simpler entry—just two selections with order flexibility—making it the most accessible exotic bet format I tested in horse racing. When stepping down from forecasts, I reverted to each-way bets or win singles. These simpler formats reduced both complexity and potential returns, but offered higher success rates suitable for smaller bankrolls or lower-confidence selections.
