Best Odds Guaranteed

On all UK and Irish racing

Best Odds Guaranteed has landed at Grosvenor Sport and is now available on all racing bets placed on UK and Irish racing on the day of race!

Simply take a price on any horse and if the starting price of your selection is bigger than the odds you took – we’ll pay you out at the greater odds.

So, if you have backed a horse at 2/1 in the morning but that horse wins at a starting price of 4/1 – you’ll be paid out at 4/1.

What’s more, if your horse is well backed and wins at a lower starting price, for example 6/4, you’ll still receive the 2/1 you locked in earlier. It’s a win-win situation!

With the extra winnings paid out at the same time as your bet is settled and all in real cash, that’s a whole lot of extra value on your racing bets.

Check our racing pages and remember, from now on you’ll be placing your racing bets with Best Odds Guaranteed.

Grosvenor Review

Best Odds Guaranteed is a sure-fire favourite, and it’s available right here on all UK and Irish Racing.

We don’t want you to pay the price for getting in there early. So, if you bet on a horse the day of the race and the starting price is bigger, we’ll pay out at the higher odds.

For example, if you back a horse at 2/1 but it goes off at 4/1, we’ll pay you out at 4/1. And if you back a horse at 4/1 and the odds come in to 2/1, you’ll still get 4/1. It’s a win-win situation.

So for great value on horse racing betting and Best Odds Guaranteed daily, Grosvenor Sport’s the place to be.
