Best Odds Guaranteed Explained

Best Odds Guaranteed can quietly boost your racing returns for free. Here's how BOG works, where it applies and how to make the most of it.

Updated 18 August 2026.

Best Odds Guaranteed (BOG) is a common promotion — mainly in horse racing — that pays you the bigger of the price you took or the Starting Price. Used well, it's free value. This guide explains how it works and how to use it, complementing what does each-way mean?.

How BOG works

With BOG, if you back a horse at 4.0 in the morning and it starts at 5.0, you're paid at 5.0; if it drifts to 3.0, you keep your 4.0. You get the better of the two prices automatically.

It removes the downside of taking an early price, which normally risks the price lengthening.

Where it applies

BOG is standard in UK/Irish horse and greyhound racing with many bookmakers, usually on win and each-way singles, subject to terms and time windows. Check the specific conditions of each promotion.

It rarely applies to exchanges, which work differently.

Why it's valuable

BOG lets you take early value confidently, knowing you'll still benefit if the price drifts. That pairs perfectly with hunting positive closing line value and betting early.

It's a genuine, free edge — one of the few promotions worth actively seeking.

Making the most of BOG

Prefer BOG bookmakers for racing, take early prices you think are value, and factor BOG into your comparisons. Note that account restrictions sometimes remove BOG for sharp accounts.

When following horse racing tipsters, BOG can help you realise closer to their advised prices.
