Ladbrokes Coral is set to extend its best odds guaranteed offer on all UK and Irish racing to its betting shops.
The firm has decided to offer its online promotion in shops to help tackle the fixed-odds betting terminals (FOBT) stake cut, which is set to take place from April 1.
Until today, best odds guaranteed bets were for online selections only - but this will now be introduced in shops.
For example, if a punter backed a horse at 10/1 and saw these odds drift to 12/1 at the start of a race, the punter would automatically be paid out at the bigger price if the bet was a winning selection.
Ladbrokes Coral will be launching its extended promotion via social media, in the press and in its betting shops.
Gala Coral Group PR director Simon Clare said: "This is the biggest racing offer ever to hit the high street and is a clear signal of our intent as we face up to a new era for betting shops from April 1.
"There is no question a seismic change in our betting shop business is going to occur when the FOBT stake restrictions come into force. But we are now taking pre-emptive action with the launch of this significant betting shop offer."
