Horse Racing Betting Guide: Each-Way, Rule 4 and Pools

Horse racing betting means backing a horse to win or to finish in the places, at a fixed price, at the starting price, or through a pool (tote). The core bets are win, place and each-way; exotic bets such as forecasts, tricasts and pool bets cover the order of several horses. Racing has more settlement rules than any other sport: place terms that change with field size, deductions when a horse is withdrawn, and dead heats. Getting those right is worth more than any tip, so this guide works through each with numbers.

What are the main horse racing bets?

How do place terms and each-way bets work?

An each-way bet is two equal bets, one on the horse to win and one on it to place. Staking “€10 each-way” therefore costs €20. Its place part is paid at a fraction of the win odds for a set number of places. The fraction and the number of places depend on the number of runners and the type of race. The table shows the common standard in Britain and Ireland, which many international bookmakers also use; bookmakers can offer better (“extra places”) or, on some races, different terms, so always read the terms shown on the race.

Worked example: an each-way bet in a big handicap

You bet €10 each-way (€20 total) at 12/1 (13.00) in an 18-runner handicap paying a quarter of the odds for four places. The place odds are 12/4 = 3/1, or 4.00 in decimal.

• Horse wins: the win part returns €130 and the place part €40, a total of €170 for a €20 stake.
• Horse finishes fourth: only the place part pays, €40 back, a €20 profit.
• Horse finishes fifth: both parts lose, a €20 loss.

Each-way value depends on the match between the price, the terms and the field. A short-priced favourite each-way in a seven-runner race (quarter odds, two places) often returns less on the place part than the stake you risk. A mid-priced horse in a big handicap with four or five places at a quarter of the odds is where each-way bets most often make sense.

Fixed odds, starting price or tote: which should you take?

You can usually bet at a fixed price (the odds when you place the bet), at the starting price (SP, the official price when the race starts) or into a pool (tote or pari-mutuel). They behave very differently.

Worked example: how a pool pays out

Suppose €100,000 is bet into a win pool and the operator’s deduction (takeout) is 15%. That leaves €85,000 to pay winners. If €10,000 was staked on the winning horse, the dividend is €85,000 ÷ €10,000 = €8.50 per €1 staked, including the stake. A heavily backed winner pays less; an unfancied one pays more. Takeout percentages are set by each pool operator and vary by country and bet type, and exotic pools usually carry larger deductions than win pools.

Worked example: Best Odds Guaranteed

Where a bookmaker offers Best Odds Guaranteed (BOG), you are paid at the better of the price you took and the SP. Back a horse at 5/1 with €10 in the morning; it drifts and starts at 7/1. If it wins, a BOG bookmaker pays €70 profit at SP instead of €50 at your price. If it shortens to 4/1, you keep your 5/1. BOG is a promotion, not a rule of racing: it is usually limited to certain races, stakes or customers, can be withdrawn, and often excludes ante-post bets and some foreign racing.

Is betting on jumps racing different from the flat?

Yes. Flat races are run without obstacles over distances from five furlongs (about 1,000 metres) to well over two miles, and draw, pace and ground often decide them. Jumps racing (National Hunt in Britain and Ireland) is run over hurdles or larger fences, usually over two to four miles and more, with fallers and unseated riders adding uncertainty that the market must price. Fields in big handicap chases can be large and open, which suits each-way betting, while novice races with few runners are often dominated by short-priced favourites.

Fitness and stamina matter more over jumps, and a horse’s record at a particular course, especially undulating ones such as Cheltenham, is worth checking. On the flat, the age of the horse, its pedigree for the trip and the ground, and the stall draw on certain tracks matter more. Bookmakers price both codes, but each-way terms and the number of runners can make the same stake behave very differently.

What is Rule 4 and how do deductions work?

When a horse is withdrawn after a betting market has formed and there is no time to form a new market, the remaining horses’ chances improve. To reflect that, bookmakers deduct a percentage of winnings from fixed-price bets on the other runners under the Tattersalls Rule 4. The size of the deduction depends on the price of the withdrawn horse at the time it was withdrawn. Deductions apply to winnings only, never to the stake, and when two or more horses are withdrawn the total deduction cannot exceed 90p in the pound.

The deduction scale is the Tattersalls Committee’s, used by British and Irish bookmakers and by many international ones for British and Irish racing. Other racing jurisdictions use their own rules, so check the bookmaker’s racing terms.

Worked example: a Rule 4 deduction

You back a horse at 6/1 with €20. Shortly before the race the 3/1 second favourite is withdrawn, a 25p deduction. Your horse wins. Winnings before deduction are €120; the deduction is 25% of that, €30, so you receive €90 in winnings plus your €20 stake, €110 in total. Had you taken SP, the market would have re-formed without the withdrawn horse and no deduction would apply, but your SP might also have been shorter than 6/1.

What happens with non-runners, dead heats and ante-post bets?

Worked dead-heat example: €10 win at 5/1 on a horse that dead-heats for first with one other. Half the stake (€5) is treated as a winner at 5/1, returning €30; the other €5 is lost. You get €30 back for your €10, a €20 profit instead of the €50 a clear win would have paid.

How do forecasts, tricasts and combination bets work?

A straight forecast names the first two in the correct order. Reverse forecasts are two bets covering both orders, so they cost double. Combination forecasts cover every order of three or more selections. Tricasts do the same for the first three places. Payouts are usually set by a computer formula (the computer straight forecast or tricast dividend) at fixed-odds bookmakers, or by the pool at tote operators.

The line counts are permutations: for a combination forecast, n × (n − 1); for a combination tricast, n × (n − 1) × (n − 2). Costs rise quickly, so combination bets suit races where you have a clear view on a small group of horses.

How do handicaps and weights work?

In a handicap race, horses carry different weights so that, in theory, they all have an equal chance. The weight comes from each horse’s official rating, set by the racing authority from its past performances: in Britain the BHA’s handicappers rate every horse that qualifies, and one rating point is roughly one pound of weight. A horse rated 85 meeting one rated 75 in the same handicap will usually carry 10 pounds more. Winners are re-rated upwards, so a horse that wins easily off a low mark is often raised before its next run.

For bettors this has two consequences. First, form in handicaps must be read with the weights: a third place carrying top weight can be a better run than a win near the bottom of the weights. Second, horses “well handicapped” (rated lower than their true ability, often after a change of trainer, trip or ground) are the main source of value in big handicaps, which is also where each-way terms are most generous.

How do pool bets like the Placepot and Jackpot work?

Multi-race pool bets ask you to pick horses across several races, and every line must succeed. The Placepot (in Britain and Ireland) needs a placed horse in each of the first six races of a meeting; the Jackpot needs the winner of six races; shorter versions cover four races. You can pick several horses per race, and the number of lines is the product of your picks: two horses in each of six races is 2⁶ = 64 lines. Dividends are shared among winning tickets after the pool deduction, so a meeting where several favourites lose can produce very large payouts, and a meeting of winning favourites can return little.

Similar pools exist worldwide, such as the Pick 4, Pick 5 and Pick 6 at US tracks, the Quinté+ in France and the Triple Trio in Hong Kong. Rules on non-runners differ by pool: in many, a non-runner is replaced by the favourite of that race. Read the pool’s rules before you build a big perm.

How is racing betting different around the world?

International bookmakers often offer fixed odds on races in all these countries, but their place terms and deduction rules for overseas racing may differ from those for British and Irish races. In US racing, “show” is the pool for the first three finishers, and “place” covers only the first two, which confuses many European bettors.

Can you bet in-play on horse racing?

Yes, at some bookmakers and especially on betting exchanges, where prices trade during the race. In-play racing moves very fast: a race lasts one to ten minutes and the leader can change in seconds. Pictures from the course reach different people with different delays, so in-play racing is dominated by traders with the fastest feeds. For most bettors it is entertainment rather than an edge. On exchanges you can also lay a horse (bet against it), which suits a view that a short-priced favourite is too short, but liability on a lay can be several times the backer’s stake.

How can you price a race yourself?

A simple approach is to give each horse your own probability of winning, check that they add up to 100%, and turn each into fair odds (1 ÷ probability). Compare your fair odds with the bookmaker’s, after allowing for its overround. Suppose you rate a horse at 20%: fair odds are 5.00 (4/1). If the bookmaker offers 6.50 (11/2), and you trust your 20% figure, the bet has an expected return of 0.20 × 6.50 = 1.30 per €1, a 30% edge on your own assessment.

The hard part is the 20%. Speed figures, the weights, the going, the draw, pace (which horses will lead) and trainer form all feed into it. Serious racing bettors keep their ratings and compare them with SP over hundreds of races to see whether their numbers are better than the market’s. If they are not, the market is the better guide.

How do you read a racecard?

A racecard lists every runner with the information you need to form a view. The key items are the same in most racing countries, though the format varies.

• Form figures: recent finishing positions, newest on the right, with letters for falls (F), pulled up (P) and other outcomes; a dash separates seasons.
• Weight and official rating: in handicaps, the weight each horse carries is set from its official rating to even out the field.
• Draw: the starting stall in flat races; on some courses and distances a low or high draw is a real advantage.
• Going: the ground conditions (firm to heavy); many horses have a clear preference.
• Distance and course form: wins at the trip (C, D, CD symbols on British cards) and on the course.
• Trainer and jockey: recent strike rates matter more than reputations.
• Days since last run and headgear: a long break or first-time blinkers can change a horse’s performance.

How do horse racing odds and margins compare with other sports?

Racing markets have many runners, so the total of implied probabilities (the overround) is usually much higher than in a two-way market. A 12-runner handicap can easily total 115% to 125% or more on early prices, which means a bigger share for the bookmaker than a football match. The overround typically falls as the market matures towards the off, and big races attract keener prices. Each-way terms are a second cost: a generous extra place is worth a lot on the place part, so it is part of the price you are buying. You can measure the overround of any race with the method on our betting odds explained page.

What are the big races coming up?

• Melbourne Cup: run on the first Tuesday of November at Flemington, which in 2026 is Tuesday 3 November; a 3,200-metre handicap with a large field and big each-way terms.
• Winter jumps season in Britain and Ireland: from November to April, building to the Cheltenham Festival in March and the Grand National meeting at Aintree in April 2027.
• Flat Classics: the Guineas, Derby and Oaks in spring and early summer 2027 in Britain, Ireland and France.
• International racing: Hong Kong’s December international races, Dubai’s World Cup meeting in March, Japan’s autumn Grade 1 races and the US Triple Crown in May and June.

Ante-post markets on these races open months ahead. Prices can be generous, but ante-post bets usually lose if the horse does not run, so check whether a bookmaker offers non-runner no bet before you commit early.

How does greyhound betting work?

Greyhound racing uses most of the same bets as horse racing: win, place, each-way, forecasts and tricasts. In Britain and Ireland races usually have six dogs, each starting from a numbered trap with a fixed jacket colour (trap 1 red, 2 blue, 3 white, 4 black, 5 orange, 6 black and white stripes). Australian and US races typically use eight boxes. Races are short, often under 30 seconds over 400 to 500 metres, and there are many meetings every day, which makes greyhounds a high-volume betting product.

The trap draw matters more than in most horse races. Dogs that run close to the rail (“railers”) prefer inside traps, wide runners prefer outside ones, and early pace out of the traps decides many races. Forecasts are especially popular in six-dog races because there are only 30 possible straight forecasts. Margins on greyhound win markets are often high, and with races every few minutes it is easy to bet more than you intended, so set a session budget before you start.

How do you bet on racing more carefully?

1. Read the each-way terms and number of places on every race before you bet each-way.
2. Decide whether to take a fixed price or SP, knowing that fixed prices are exposed to Rule 4 deductions.
3. Look for non-runner no bet before backing ante-post.
4. Check the going and the draw; both can outweigh recent form.
5. Compare prices and place terms at two or three bookmakers; extra places are worth real money.
6. Keep records of every bet with the price taken and the SP; beating SP over time is a good sign.
7. Set a daily budget. With racing every few minutes, volume is the biggest cost.
8. Be sceptical of paid tipsters: anyone with a proven edge has little reason to sell it, and records are easy to present selectively.

Frequently asked questions

How does an each-way bet work?

It is two equal bets: one on your horse to win and one on it to finish in the places. A €5 each-way bet costs €10. If the horse wins, both parts pay; if it only places, the place part pays at the fraction of the odds in the race terms, such as a quarter or a fifth.

How many places are paid in horse racing?

Under the common British and Irish standard: no each-way with 2 to 4 runners, 2 places at 1/4 odds with 5 to 7, 3 places at 1/5 odds with 8 or more in non-handicaps, 3 places at 1/4 in handicaps of 12 to 15 runners, and 4 places at 1/4 in handicaps of 16 or more. Bookmakers can offer more places.

What is a Rule 4 deduction?

It is a deduction from the winnings of fixed-price bets when a horse is withdrawn too late for a new market to form. The amount depends on the withdrawn horse’s price, from 5p to 90p in the pound, and the total for several withdrawals in one race cannot exceed 90p. Stakes are never reduced.

What happens if my horse is a non-runner?

On a race-day bet your stake is returned, and in a multiple that leg is void. On an ante-post bet the stake is usually lost unless the bookmaker offered non-runner no bet on that race.

Is it better to take the price or SP?

Taking a fixed price is better if you think the horse will shorten before the race; SP is better if you expect it to drift or if there may be late withdrawals that would trigger Rule 4. Best Odds Guaranteed, where offered, gives you the higher of the two.

How does a tote bet pay out?

All stakes go into a pool, the operator takes a percentage, and the rest is shared among winning tickets. If €85,000 is left after the deduction and €10,000 was bet on the winner, each €1 ticket returns €8.50. You only know the dividend once the result is official.

How many dogs run in a greyhound race?

Usually six in Britain and Ireland, each from a numbered trap with a fixed colour, and usually eight in Australia and the United States. Fewer runners mean fewer possible forecasts, which is why forecast bets are popular in greyhound racing.
