Best Odds Guaranteed Bookmakers

Take a price on a race and if the starting price ends up bigger, you're paid at the bigger one. Every bookmaker below runs a version of it — but the qualifying rules, the caps and the exclusions vary. This compares them on their own live terms rather than just listing names.

Things worth knowing about best odds guaranteed

It applies to race-day bets, not ante-post
Almost every bookmaker starts the guarantee at a set time on the morning of the race. A bet struck weeks in advance at a big price is an ante-post bet and normally sits outside it.
It doesn't make a bad price good
BOG protects you against a drift; it doesn't protect you against taking a short price in the first place. Comparing the price before you bet still matters more.
Watch for “selected players”
Several operators reserve the right to apply it only to some accounts. If the terms say selected players or selected races, check it's showing on your betslip before you rely on it.
