Ballarat's Riding for the Disabled and McCallum Disability Services are among those hoping to be randomly drawn and allocated a greyhound in this year's final.

Riding Develops Abilities in Maryborough and Ararat's Manna Gums Nursery and Wood 'n' Crete are also part of the draw.

The draw will take place at about 5.15pm on Wednesday via a private zoom link for all 22 groups, eight of which will be paired with a dog.

The winner will receive $10,000, while the other seven groups collect $2000 each.

First run in 2003, the annual Great Chase is a state-wide event which traditionally sees groups that care for the disabled enjoy free days out at their local greyhound racetrack, where they receive meals, showbags and are allocated greyhounds for the day.

The better-performing dogs win prizemoney for their group, with almost $650,000 distributed to Victoria's disability sector so far.
