Best Odds Guaranteed (BOG) is the name of a horse racing promotion. If the starting price (SP) ends higher than the price you took, the bet is paid at the higher price. If it ends lower, you keep the price you took. BOG concerns the price only, not whether a bet wins. Conditions are set by each operator and are Not checked here.

## What BOG means

You take a price on a horse before the race. The race starts, and the starting price is set. Under a BOG promotion the operator pays the larger of the two.

Without the promotion, case A below would pay 3/1 (4.00), a return of €40. [Odds formats](https://beforeyouinstall.com/guides/odds-formats-explained/) explains the notation.

**In short:** BOG pays the bigger of your price and the starting price.

## Worked example

Example only, with invented prices.

**Example: €10 stake with BOG terms, returns include the stake. Source: our own calculation, invented prices · checked 7 November 2026**

| Case | Price taken | Starting price | Paid at | Return |
|---|---|---|---|---|
| A: price drifts out | 3/1 (4.00) | 5/1 (6.00) | 5/1 (6.00) | €60.00 |
| B: price shortens | 5/1 (6.00) | 3/1 (4.00) | 5/1 (6.00) | €60.00 |
| C: price unchanged | 4/1 (5.00) | 4/1 (5.00) | 4/1 (5.00) | €50.00 |

**In short:** In cases A and B the promotion pays €60; in case C it changes nothing.

## Where the condition shows

ASA Code 4.37–4.38, as summarised in our country brief, expects the conditions of a guarantee to be available before you bet. Which races, bet types and cut-off times a BOG promotion covers: Not checked.

Two neighbouring terms matter. See [starting price](https://beforeyouinstall.com/guides/starting-price-meaning/) and [void bet and Rule 4](https://beforeyouinstall.com/guides/void-bet-and-rule-4-meaning/) for what happens when a runner is removed.

**In short:** Check the terms before the bet, not after the race.

## A name, not a promise

The word guaranteed here is part of the promotion's name. It describes how the price is set. ASA Code 10.12(k) bars promising a win, so this site uses the word only inside the promotion's name.

We do not compare operators' BOG terms on this page. For place bets on the same races, see [each-way](https://beforeyouinstall.com/guides/each-way-meaning/).

**In short:** BOG protects the price; it never promises an outcome.

## How we checked

**In short:** Only the dated items above were checked; everything marked Not checked is still open.
