5 of the 6 horses are named craiglea ***
5 of the 6 horses are from the same trainer.

The prize money for the race is :

Of $10,000.1st $6,500, 2nd $2,000, 3rd $1,000, 4th $500
Handicap, Minimum Weight 54kg, Two-Years-Old, Apprentices can claim.
QTIS600 Bonuses: First $14000, Second $4000, Third $2000, to qualified horses.

Whats a trainers cut of that ? I assume they get 10% or something ? Assuming they are all qualify for the bonus he could potentially make $2150 at 10% for 1 day at the races in a no hoper race.

Even if they don't qualify he could get 1000 at 10% cut.
