The British Horseracing Authority (BHA) has agreed to alter the controversial whip rules that were introduced last month.
Riders are still limited in the whip's usage, the rules now allowing them to strike the horse only seven times in flat races and eight times in a jump race.
They will now however be able to use that allocation at any point in the race and could still lose prize money if they exceed the allowance.
The move comes after discussions with a selection of riders and the Professional Jockeys Association (PJA) on Monday.
The new ruling becomes effective as of this afternoon's racing.
