Best Odds Guaranteed (BOG) is a bookmaker offer that settles an eligible winning horse racing bet at the bigger of the fixed price you took and the official Starting Price (SP). It can increase your return when a horse drifts in the betting after you place your bet.
For example, you back a horse at 6/1 and it wins at an SP of 10/1. If your bet qualifies for BOG, it is settled at 10/1. If the horse starts at 4/1, you keep the original 6/1.
BOG is useful for bettors who take early prices, but it does not apply automatically to every horse racing bet. Bookmakers can restrict the races, bet types, qualifying times and customers covered by the offer.
British Racecourses compares BOG as one part of a bookmaker’s horse racing service. The price available when you place the bet, each-way terms and other restrictions still matter.

Best Odds Guaranteed Bookmakers
The bookmakers British Racecourses currently recommends include several operators with horse racing price guarantees or related racing products.
The important distinction is between a bookmaker that offers BOG on a qualifying fixed-odds market and one that offers a different type of price guarantee.
| Bookmaker | What to Compare |
|---|---|
| bet365 | Eligible early-price markets, qualifying time and exclusions for alternative each-way terms |
| BoyleSports | The qualifying BOG market, early-price availability and bet-type restrictions |
| William Hill | Eligible horse racing markets and the conditions applying to online or shop bets |
| BetVictor | Qualifying fixed-odds markets and restrictions on promotional bets |
| Ladbrokes | Eligible races, bet types and any separate shop or online conditions |
| Coral | Eligible races, bet types and any separate shop or online conditions |
| Betfred | Qualifying time, eligible markets and differences between online and shop betting |
| Tote | Tote Guarantee, which compares qualifying pool dividends with SP rather than operating as an ordinary fixed-odds BOG offer |
A bookmaker appearing in this table does not mean that every customer, race or bet qualifies for its guarantee. Check the terms displayed for the market before placing a wager.
For a comparison of bookmakers beyond BOG, see our Best Horse Racing Betting Sites page.
What Is Best Odds Guaranteed?
Best Odds Guaranteed protects an eligible early price against a drift to a bigger official Starting Price.
When you take a fixed price, you normally agree the odds at which your bet will be settled if it wins. BOG adds a qualifying price guarantee: if the official SP is bigger, the bookmaker uses that bigger price.
BOG does not improve a losing bet. It also does not guarantee that you took the biggest price available across all bookmakers.
The guarantee compares two prices for the same qualifying bet: the fixed price you accepted and the official SP.
Best Odds Guaranteed Example
Suppose you place a £10 win bet on a horse at 6/1.
| Outcome | Settlement Price | Total Return |
|---|---|---|
| Horse wins at 4/1 SP | 6/1 | £70 |
| Horse wins at 6/1 SP | 6/1 | £70 |
| Horse wins at 10/1 SP | 10/1 | £110 |
| Horse loses | Losing bet | £0 |
These figures assume the bet qualifies for BOG and no deductions apply.
Without BOG, the winning bet would normally be settled at the fixed 6/1 price you accepted, even if the horse started at 10/1.
How Does Best Odds Guaranteed Work?
A qualifying BOG bet follows a straightforward settlement process.
You select a horse in an eligible market and accept the available fixed price. When the race starts, the official SP is returned. If the horse wins, the bookmaker compares your accepted price with SP and settles the bet at the bigger of the two.
If SP is shorter than your fixed price, you retain your original odds.
The guarantee does not mean that every price movement during the day is considered. A horse might briefly drift to 12/1 and then start at 8/1. If you took 10/1, a conventional BOG settlement uses your 10/1 because it is bigger than the official 8/1 SP.
The precise terms of the bookmaker’s offer determine eligibility.
bet365 Best Odds Guaranteed
bet365’s horse racing service includes fixed-odds markets and racing-specific betting features.
For BOG, check the qualifying time and the market selected on the bet slip. A standard win or each-way market can have different conditions from an enhanced-price or alternative each-way market.
The availability of an early price does not, by itself, establish that BOG applies to the wager.
This distinction matters when comparing an ordinary each-way bet with a market offering a different number of places or adjusted odds.
BoyleSports Best Odds Guaranteed
BoyleSports is among the bookmakers covered by British Racecourses for horse racing betting.
When comparing its BOG terms, establish when the guarantee begins, which races qualify and whether it applies to the type of bet you intend to place.
An early market may be available before the BOG qualifying period. A bet placed before that period should not be assumed to receive the guarantee retrospectively.
Compare the fixed price available with the terms attached to that specific market.
William Hill Best Odds Guaranteed
William Hill’s horse racing markets can be compared for early prices and qualifying BOG terms.
Check whether the offer applies to the race, market and bet type you have selected. Online and betting-shop conditions should not be assumed to be identical.
If you are placing a multiple bet, check how the bookmaker treats eligible and ineligible selections within the same bet.
A general statement that William Hill offers BOG does not establish that every wager qualifies.
BetVictor Best Odds Guaranteed
BetVictor is another bookmaker to consider when comparing horse racing prices and guarantees.
Check the eligible markets, qualifying time and any restrictions applying to enhanced odds, promotional credits or alternative bet types.
A bigger early price can be useful even without BOG. The relevant comparison is the price and terms actually available when you place the bet.
Ladbrokes Best Odds Guaranteed
Ladbrokes offers horse racing markets in which the applicable price guarantee should be checked before betting.
The qualifying conditions can differ by market and betting channel. Do not assume that an online promotion also applies to every over-the-counter bet, or vice versa.
For each-way betting, compare the place fraction and number of paid places alongside BOG eligibility.
Coral Best Odds Guaranteed
Coral’s horse racing markets can be assessed using the same factors: the fixed price, qualifying time, eligible bet types and settlement rules.
If a race has an extra-place promotion, establish whether it uses a separate market and whether that market qualifies for BOG.
The number of places offered does not establish that a bet also receives a price guarantee.
Betfred Best Odds Guaranteed
Betfred provides horse racing markets online and through betting shops.
Check the applicable BOG terms for the channel you use. The qualifying time, eligible markets and other restrictions may differ.
A bet accepted at an early price is not automatically a BOG bet. Confirm the guarantee before placing the wager.
Is Tote Guarantee the Same as Best Odds Guaranteed?
No. Tote Guarantee and conventional fixed-odds BOG are different products.
A Tote bet is a pool bet. Its dividend is determined through the relevant betting pool rather than by accepting an ordinary bookmaker’s fixed price.
Tote Guarantee compares the qualifying Tote dividend with the applicable SP under its own terms. It should not be described as a fixed-odds BOG offer.
This distinction matters because the bet structure, dividend calculation and qualifying conditions are different.
Readers considering Tote should compare its pool-betting product on its own terms rather than assume that a fixed-odds BOG example applies to every Tote bet.
What Time Does Best Odds Guaranteed Start?
There is no single BOG start time that applies to every bookmaker.
Some offers can begin when qualifying early markets open, while others apply only to bets placed during a specified period on race day.
The start time can also differ by race, betting channel or promotional market.
An early price being available does not mean that BOG is already active.
Check the terms before placing the bet. If the guarantee begins later, a wager accepted earlier may remain an ordinary fixed-price bet.
Does Best Odds Guaranteed Apply the Night Before Racing?
It can, but only where the bookmaker’s terms make the bet eligible.
Some bookmakers open early-price markets the previous evening. That does not establish that every wager placed in those markets qualifies for BOG.
Check the qualifying period and the selected market rather than relying on a general claim that a bookmaker offers night-before BOG.
For an early bet, also establish whether the market is ordinary ante-post, non-runner no bet or a race-day market. Those terms affect what happens if the horse does not run.
Does Best Odds Guaranteed Apply to Ante-Post Bets?
Ordinary ante-post bets generally do not qualify for BOG.
An ante-post wager is accepted before the final field is declared. Under ordinary ante-post terms, the stake generally loses if the horse does not take part.
BOG is a price-settlement offer. It should not be confused with non-runner no bet, which concerns the return of a qualifying stake if a horse does not run.
A bookmaker may operate separate markets with different protections. Check the exact market name and conditions before betting.
Best Odds Guaranteed on Each-Way Bets
An each-way bet consists of two equal parts: one on the horse to win and one on it to finish in a qualifying place.
BOG can affect the settlement of an eligible each-way bet, but the bookmaker’s rules determine how the guarantee applies to the win and place portions.
The number of places and place fraction remain important.
Each-Way BOG Example
Suppose you place a £10 each-way bet at 8/1 with one-fifth place terms. The total stake is £20.
If the horse wins at an SP of 12/1 and both parts of the wager qualify for BOG, the win part returns £130, including its £10 stake.
The place odds at one-fifth of 12/1 are 12/5. The place part returns £34, including its £10 stake.
The combined return is £164, giving a net profit of £144 on the £20 total stake.
Without a qualifying BOG improvement, settlement at the original 8/1 would produce a smaller return.
This is an illustrative calculation. Actual settlement depends on the bookmaker’s terms and any applicable deductions.
Does BOG Apply to Extra-Place Markets?
Not automatically.
A bookmaker may offer extra places through a separate market with different win odds, place fractions or promotional conditions.
Some alternative each-way markets do not qualify for the ordinary BOG offer.
Check the market displayed on the bet slip. Do not assume that a standard-market guarantee transfers to an extra-place selection.
Our extra-place betting sites page explains the other terms to compare.
Best Odds Guaranteed on Multiples
BOG can apply to eligible selections in some multiple bets, but the rules vary by bookmaker and bet type.
A double or treble may be treated differently from a Lucky 15, Lucky 31 or Lucky 63. Some bookmakers exclude certain multiples or promotional bet types altogether.
Where a multiple contains both qualifying and non-qualifying selections, the settlement depends on the bookmaker’s terms.
Do not assume that every leg of a multiple receives BOG simply because one selection qualifies.
The bet slip and the bookmaker’s published rules should establish how the wager will be settled.
Best Odds Guaranteed and Rule 4 Deductions
A Rule 4 deduction can apply when a horse is withdrawn after you have taken a fixed price.
The deduction reduces the relevant winnings according to the applicable betting rules. It is separate from the BOG comparison.
BOG does not automatically cancel a Rule 4 deduction.
The order and method of settlement depend on the bookmaker’s terms and the circumstances of the withdrawal.
For example, a bet may qualify for a price guarantee but still be subject to an applicable deduction after a non-runner.
Check the settlement details rather than assuming that the bigger price will be paid without adjustment.
Does Best Odds Guaranteed Apply to Free Bets?
Not necessarily.
Bookmakers may exclude wagers funded with free bet credit from BOG. Others may have specific rules for promotional stakes and qualifying markets.
Free bet stakes are also commonly excluded from winnings, which changes the return compared with an ordinary cash bet.
A free bet promotion and a BOG offer should therefore be assessed separately unless the bookmaker explicitly permits them to be combined.
Our horse racing free bets page explains the different types of betting credit.
Best Odds Guaranteed in Betting Shops
BOG can be available through betting shops, but the terms may differ from those offered online.
Check the qualifying time, eligible races and bet types at the shop where you place the wager.
A bookmaker may have different arrangements for early prices, board prices and bets accepted over the counter.
Keep your betting slip and review the terms applicable when the bet was accepted.
A general online BOG promotion should not be assumed to cover a shop bet.
Does BOG Apply to Greyhound Racing?
Some bookmakers offer price guarantees on qualifying greyhound racing bets, but horse racing BOG terms should not be assumed to apply.
Greyhound offers can have different qualifying times, race coverage and exclusions.
If you are betting on greyhounds, check the specific greyhound terms rather than relying on a bookmaker’s horse racing promotion.
Is Best Odds Guaranteed Always Worth Using?
BOG can improve the settlement price of an eligible winning bet when the horse starts at bigger odds than the price taken.
However, it does not compensate for taking a poor price in the first place.
Suppose one bookmaker offers 5/1 with BOG and another offers 7/1 without it. The BOG bookmaker will not necessarily provide the larger return. The result depends on the official SP and the terms of each bet.
The available fixed price should therefore be compared before the guarantee is considered.
BOG also does not reduce the risk of the horse losing. A qualifying bet on a losing selection still loses unless a separate promotion applies.
How to Compare BOG Bookmakers
A useful BOG comparison starts with the bet you intend to place.
For an ordinary win bet, compare the available fixed prices, qualifying times and market restrictions.
For an each-way bet, also compare the number of places and place fraction. An extra-place market may have different BOG eligibility from the standard market.
For a multiple, check whether each selection qualifies and whether the bookmaker applies the guarantee to that bet type.
Finally, review any maximum promotional benefit or settlement restriction in the current terms. Do not rely on an old limit quoted in a previous bookmaker review.
Our Best Horse Racing Betting Sites comparison covers BOG alongside odds, each-way terms, withdrawals and other account features.
Best Odds Guaranteed FAQs
What does Best Odds Guaranteed mean?
BOG means an eligible winning bet is settled at the bigger of the fixed price taken and the official Starting Price, subject to the bookmaker’s terms.
Is Best Odds Guaranteed available on every horse race?
No. Eligibility depends on the bookmaker, race, market, qualifying time and other conditions.
What happens if the Starting Price is shorter?
A qualifying BOG bet keeps the original fixed price if it is bigger than SP.
What happens if the Starting Price is bigger?
An eligible winning bet is settled at the bigger SP, subject to the bookmaker’s terms and any applicable deductions.
Does BOG apply to losing bets?
No. BOG changes the settlement price of an eligible winning bet. It does not turn a losing selection into a winning one.
Can I get BOG the night before a race?
Only if the bookmaker’s qualifying terms cover the bet placed at that time. An early-price market being open does not automatically mean BOG applies.
Does BOG apply to ante-post betting?
Ordinary ante-post bets generally do not qualify. Check the exact market and terms.
Does BOG apply to each-way bets?
It can apply to qualifying each-way bets, but the treatment of the win and place portions depends on the bookmaker’s rules.
Does BOG apply to extra places?
Not automatically. Extra-place markets can have separate terms and may be excluded from standard BOG offers.
Does BOG apply to Lucky 15 bets?
It depends on the bookmaker. Check whether the guarantee covers the multiple bet type and the individual selections.
Does BOG remove Rule 4 deductions?
No. An applicable Rule 4 deduction can still affect settlement.
Is Tote Guarantee the same as BOG?
No. Tote Guarantee relates to qualifying pool-betting dividends and SP. Conventional BOG compares an accepted fixed price with SP.
Which bookmaker has the best BOG terms?
The relevant comparison depends on the race, available fixed price, qualifying time, bet type and current terms. No bookmaker should be assumed to provide the same BOG conditions on every wager.
Summary
Best Odds Guaranteed can improve the return on an eligible winning horse racing bet when the official Starting Price is bigger than the fixed price taken.
The guarantee does not apply automatically to every race or market. Qualifying times, each-way terms, multiples, free bets and promotional exclusions can differ between bookmakers.
Compare the available price first, then check whether the specific bet qualifies for BOG. For the wider bookmaker comparison, visit our Best Horse Racing Betting Sites page.
