Dutching in Horse Racing: How to Back Multiple Horses and Guarantee Equal Profit
One Race, Two Horses, Equal Profit — That Is Dutching
I backed two horses in a six-runner novice hurdle last January. One was 5/2, the other 7/2. Both had solid claims on the form. I liked them equally, and picking just one felt like flipping a coin with my bank. So I dutched them — distributed my total stake proportionally so that whichever horse won, my profit would be identical. The 7/2 shot came through and I collected exactly the same return I would have pocketed if the 5/2 had won instead. No regret, no what-ifs. That is the entire appeal of dutching in a single race.
Dutching is not a new idea. It dates back to a bookmaker called Arthur “Dutch” Schultz in the 1930s, who used the principle from the other side of the market. For punters, the logic is simple: when you genuinely cannot separate two or three horses, you spread your stake across them in proportion to their odds. The result is a level profit regardless of which selection wins. In fields of six runners, where public favourites win roughly 40% of races at average prices a touch above even money, the remaining 60% is shared among horses that can often be narrowed to two or three realistic contenders — and that is where dutching earns its keep.
The Dutching Formula: Calculating Stakes for Equal Returns
The maths behind dutching is cleaner than most punters expect. You do not need a calculator, though one helps when you are working with three or more selections. The core principle is this: divide your total stake among your selections so that each potential winner produces the same total return.
Start with the decimal odds. If Horse A is 3/1 (decimal 4.0) and Horse B is 5/1 (decimal 6.0), convert each into an implied probability: 1/4.0 = 0.25 for Horse A, 1/6.0 = 0.167 for Horse B. Sum those probabilities: 0.25 + 0.167 = 0.417. Now divide each horse’s individual probability by the combined figure to get the proportion of your stake it receives. Horse A gets 0.25/0.417 = 59.95% of the stake. Horse B gets 0.167/0.417 = 40.05%.
On a £50 total outlay, you would place £30 on Horse A (3/1) and £20 on Horse B (5/1). If Horse A wins, you collect £120 (£30 x 4.0), a profit of £70 after deducting the total £50 stake. If Horse B wins, you collect £120 (£20 x 6.0), the same £70 profit. Identical return, split two ways.
For three or more selections, the method scales identically. Sum the implied probabilities of all your picks, then allocate each horse’s share proportionally. The critical number to watch is the combined implied probability. If it exceeds 100% — which happens when you dutch too many short-priced selections — you are guaranteed a loss regardless of which horse wins. That is the overround working against you, and it is the same mechanism that gives bookmakers their margin on every race.
When Dutching Works: Race Scenarios That Favour Multiple Selections
Not every race deserves a dutch. I tried dutching every maiden at Kempton for a month once, and the results were miserable — because in half those races, I could not actually identify a genuine edge on any runner, let alone two. Dutching works when your analysis produces two or three shortlisted horses, each with a plausible path to winning, and the combined odds still leave room for profit after accounting for the bookmaker’s margin.
Small-field races with dominant form contenders are the sweet spot. In a six-runner conditions chase where you have narrowed the field to two based on class, going preference and recent form, your combined implied probability often sits around 50-60%, while the bookmaker’s combined prices on those two might be 70-75%. That gap is your edge — the market is offering you better value on the pair than their combined true chances suggest.
Handicaps with 16 or more runners tend to be harder to dutch profitably because the prices of any shortlisted horses are longer, meaning the overround eats more of the margin. However, if you specialise in big-field handicap betting and can isolate two or three live outsiders at 10/1 or longer, the combined implied probability stays low enough that dutching delivers a healthy return when one of them wins.
The worst scenario for dutching is a race with a hot favourite at 4/6 and several unconsidered outsiders. Including the favourite in your dutch inflates the combined probability rapidly, leaving almost no room for profit. If you need to include a short-priced horse, the other selections must be long enough to compensate.
Dutching vs Each-Way: Which Spreads Risk More Efficiently?
I am often asked whether dutching or each-way betting is the better way to cover more than one outcome in a race. The answer depends on what you are trying to achieve, and the distinction matters more than most punters realise.
Each-way betting gives you two bets on a single horse: one to win, one to place. It spreads risk vertically — your horse does not need to win for you to collect, it just needs to finish in the place positions. Win bets account for 36% of all horse racing wagers in the UK, while each-way bets represent roughly 22% — together, these two formats dominate the market. Dutching spreads risk horizontally — across multiple horses in the same race, each needing to win for you to profit.
When there is a clear standout whose biggest risk is finishing second or third rather than missing the frame entirely, each-way is the sharper tool. When the race is open and two or three horses have similar chances of winning but place returns are thin (common in small fields with only two place positions), dutching gives you a better profit-to-outlay ratio.
The hybrid approach — dutching two each-way bets — is viable in large fields where place terms are generous (four or five places paid). The outlay is higher and the calculations become more involved, but the coverage is wide. I use this sparingly, typically only in festival handicaps where the each-way terms are extended and I have a pair of live outsiders.
Common Dutching Errors and How to Avoid Them
The most destructive dutching mistake I see is what I call “comfort dutching” — adding a third or fourth horse to the dutch purely to feel covered, without any form-based justification. Every additional selection increases the combined implied probability and shrinks your potential return. If you cannot explain in one sentence why a horse is in your dutch, it should not be there.
Second: ignoring the overround. A race with a 125% overround is already taking 25% from the combined market. If your dutched selections carry a combined implied probability of 50%, you need those horses to genuinely represent at least 62-63% of the true probability to break even. Check the overround before you commit. If it is above 130%, the margin for profitable dutching is razor thin.
Third: rounding stakes carelessly. A £1 rounding error on a £30 dutch across three horses can shift your profit by 10-15%. Use precise stakes, even if it means placing odd amounts like £13.40. Most online bookmakers accept stakes to the penny, and the precision matters over hundreds of bets. And if the prices shift between calculating your stakes and placing the bets, recalculate. A price that drifts from 4/1 to 7/2 changes your entire stake allocation, and placing the original amounts guarantees an unequal return.
Can I dutch on a betting exchange as well as with a bookmaker?
Yes. Exchanges often offer better dutching value because their odds are typically higher (no overround, just commission). The combined implied probability of your selections tends to be lower on an exchange, leaving more room for profit. The trade-off is that liquidity can be thin on smaller races, making it harder to get your full stakes matched.
Is dutching profitable in the long run or does the overround kill the edge?
Dutching is profitable only if your horse selection carries genuine positive expected value. The overround reduces your margin, but it does not eliminate it. If you are dutching two horses whose combined true probability exceeds the combined bookmaker implied probability, the edge survives. Track your results over at least 200 dutched bets before drawing conclusions.
How many selections is too many when dutching a race?
Three is a practical ceiling for most races. Beyond three, the combined implied probability usually exceeds the point where profit is meaningful. In rare cases — large-field handicaps with generous prices — four selections can work, but the return per bet drops sharply. Stick to two or three unless the numbers explicitly support more.
