Best Odds Guaranteed (BOG) Explained: The Ultimate Guide

Best Odds Guaranteed (BOG) Explained: The Ultimate Guide

Ever placed a horse racing bet early, only to see the odds drift and wish you’d waited?

Best Odds Guaranteed (BOG) is a horse racing and greyhound racing-related betting promotion that many of the UK’s best bookmakers regularly offer, which can solve this issue. It allows punters to get the best odds when used before the race starts.

In this guide, we will cover everything you need to know about the BOG promotion and how to make the most of it. We’ll share simple step-by-step guides and cover all the important information about the specific terms and conditions of this promotion, helping you become a BOG expert in minutes!

What Does Best Odds Guaranteed (BOG) Actually Mean?

Best Odds Guaranteed is a racing-related promotion that offers punters the potential to obtain the best odds ahead of a race. This only happens if the Starting Price (SP) of your horse or greyhound is higher than the odds you initially took. If so, you get paid at the higher price.

Punters should understand that two terms are of vital importance that pertain to this betting offer:

• Early Price (Board Price): These are the fixed odds that are taken before the start of a race when the bet is initially placed.
• Starting Price (SP): This is the price of the odds that are available at the exact moment that the race starts.

To help people understand BOG offers better, some keep the following analogy in mind:

“Think of it as a price promise. You’re guaranteed not to miss out on a better price if one becomes available after you’ve bet.”

How BOG Works in Practice: Two Clear Scenarios

Want to know how BOG promotions work? We’ve provided two simple scenarios below with numbers to help make them easier to understand and ensure you have a solid foundation about how they can be used:

Scenario 1: The Odds Drift (BOG Helps You)

The Best Odds Guaranteed betting offer can help a punter to receive a better price, especially if they place their bets some time before a race. This can be common, as many want to get as much value as they can, with odds liable to change in the lead-up.

For some, odds can drift and become longer than the odds that they initially backed. A BOG offer can provide them with the opportunity to get the latter price if it stays longer than their fixed odds at the time of the race start.

Consider the following scenario:

The profit in this scenario is an additional £20, making the BOG promotion prove to be extremely valuable.

Scenario 2: The Odds Shorten (You Keep Your Better Price)

An additional scenario could be the reverse of the first one. You may like the early value a horse shows on the day of a race. You place a bet on it at the time, but then notice the odds begin to fall (get shorter) as more people back it.

The BOG promotion allows punters to get the price that they backed, meaning they won’t be out of pocket if the SP is lower than the initial odds taken.

With the BOG offer, the lower price is always ignored, and the bettor gets the highest available price. In this scenario, that will be the price they take if the odds continue to shorten.

The Flashscore Difference: Visualising a Real BOG Scenario

Below is a visual example of how a horse racing card can look on Flashscore before and after a race, with the notable changes in the SP (final column to the right). In the first screenshot, the odds are shown as of 17:29 on 24/10/25. In the next screenshot, they are taken once the race has finished (18:03).

When looking at the comparison, it is possible to see that the winner of the race ‘Cornmarket’ went off at a SP price of 11/2. However, in the lead-up to the race, the horse was being shown at 7/2, indicating that there had been value in backing him as his odds lengthened. Punters who backed it using a bookie offering BOG would have received the 11/2 price, instead of the 7/2, meaning they would receive £5.50 profit for every £1 staked on the ‘win’ instead of £3.50 profit.

Odds after the race:

Which Bookmakers Offer Best Odds Guaranteed? (And When It Starts)

Bettors are spoiled for choice when it comes to BOG offers. Many of the top UK sportsbooks consistently offer this promotion, allowing them to capitalise on making early bets.

It’s important to check out the terms and conditions, as each bookie can differ. For example, the William Hill Best Odds Guaranteed time is different to the BetVictor Best Odds Guaranteed time.

Recognising these times and when they are can provide just as much value as comparing multiple bookmakers together when trying to find the best site to use.

Below, we’ve provided you with a comparison table of the top bookies in the UK. Note, the information is correct as of October 2025, but promotions can change. Always check the terms and conditions directly with the bookmaker before betting.

Important Rules & Restrictions to Be Aware Of

As with all betting promotions, several terms and conditions must be met when using a Best Odds Guaranteed bonus. Outlined below are some of the most common restrictions that can be found associated with this type of offer:

• Times: Each bookie is different; some allow BOG to be obtained from 08:00 on the day of the race, while others are slightly later.
• Qualifying Races: Typically only available for UK & Irish Horse Racing meets; can include greyhound racing at times.
• Excluded Bets: Some bets are excluded from a BOG offer. These include: Ante-Post bets, tote/pool bets, and in-play bets.
• Account Restrictions: A bookmaker may restrict certain accounts and not offer the promotion.
• Maximum Payout: A maximum payout limit can be applied, capping what can be won from the BOG offer.

Conclusion

Best Odds Guaranteed is a betting promotion offered by many UK bookmakers to horse and greyhound racing punters. It is typically applicable only to races held in the UK or Ireland and comes with specific restrictions.

A BOG offer is typically only available from 08:00 GMT/BST on the day of a race, right up to its start time. Some bookies do have different times (e.g., 09:00 GMT/BST), so it’s important to check the terms and conditions beforehand.

Bettors must remember to practise responsible gambling measures, even when using a promotion like BOG offers. Bettors should only ever wager within their limits, setting budgets to protect themselves and stick to. Only ever use a licensed UKGC bookmaker to ensure a fair betting experience is obtained.
