On top of the usual spring riches, jockeys and trainers will be riding for extra prize money in the Spring Racing Carnival Premierships.

But the bigger winners will be the 11 charities associated with the riders and trainers.

The leading jockey and trainer will pocket $25,000 while their nominated charity will collect the same amount.

The young gun rider, a jockey under 26 years of age, will take home $5000 matched by a donation to their charity.

Along the way a $1000 donation will be made to the charity of the leading jockey and trainer at each of the 12 racedays, commencing with Saturday's Underwood Stakes meeting.

The final meeting at Sandown on November 14 will see $2000 donated to the charity of the leading jockey and trainer.

Dwayne Dunn defeated Damien Oliver in the inaugural Spring Racing Carnival Premiership for jockeys last year while David Hayes and Tom Dabernig won the trainers' prize.

Oliver exacted revenge later in the season when he claimed a 10th Melbourne jockeys' premiership, relegating Dunn into third.

"I did get a little bit square in the jockeys' premiership with Dwayne and I said to him I'd swap the twenty-five thousand for the jockeys' premiership, but he wasn't too forthcoming with that," Oliver said.

Points will be awarded on a 3,2,1 basis with Group One races and the Group Two Zipping Classic attracting double points.

The Caulfield Cup, the Cox Plate and the Melbourne Cup will have 12 points up for grabs the winning jockey and trainer.
