238. During a two in three race, an amount of 10% of the purse is attributed to the owner of the horse that is declared the winner.
The rest of the purse is divided equally among the first 2 or 3 heats, as the case may be, unless the conditions for participating in that race provide otherwise.
Where it is necessary to have a fourth heat for a horse to be declared the winner of the race, the purse for that fourth heat is 10% of the amount reserved for the owner of the horse that is declared the winner in the race and it is taken from that amount.
Decision 96-07-24, s. 238.
