Stawell-based jockey and trainer Linda Meech will be segregated from the rest of the racing fraternity as part of an unprecedented initiative to ensure the industry survives the COVID-19 pandemic.
Twenty-five top jockeys will not be allowed to race outside of race-days and will be asked to isolate themselves as much as possible.
Racing Victoria formed the group, in association with the Victorian Jockeys Association, to allow racing to continue should a rider be diagnosed with coronavirus.
Horsham jockey Dean Yendall opted out of the group.
Meech addressed the isolation after riding Shea Eden-trained Alsvin to victory in race one at The Valley on Friday night.
"I think I've got a few lonely weeks coming up. Hopefully they get this virus under control and we can get on with our lives. But we've got all our practices in place," she told racing.com post race.
Meech also rode Trent Busuttin and Natalie Young-trained Inverloch to a second-place finish at Saturday's Mornington Cup, before riding at a Ballarat meet the following day.
All races - including next month's Stawell Cup - are closed to the public until April 13 to slow the spread of the coronavirus.
Racing Victoria may yet implement more measures, after the state government announced it would begin to shut down all non-essential activity over the next 48 hours.
Racing Victoria chief executive Giles Thompson said unprecedented measures had to be implemented to ensure racing continues.
"As we have stated repeatedly, these are unprecedented times that require unprecedented actions to achieve our goals of protecting the health and wellbeing of industry staff and participants; and ensuring that our programmed race meetings can proceed," he said.
The isolated jockeys will not be allowed to ride trackwork, trials or jumpouts and are also not permitted to travel to race meets with any jockey outside the group.
The group was also encouraged to stay at home as much as possible.
Melbourne Cup winners Craig Williams and Damien Oliver are among those to have agreed to the initiative.
"The segregation of our riders into groups is all about providing the industry with options should a rider be diagnosed with COVID-19," Mr Thompson said.
"In simple terms, this is another insurance policy to help the industry keep ticking along whilst many other sports have been forced to suspend competition.
"I want to take this opportunity to again thank all within our industry for their understanding and cooperation in these unique and trying circumstances.
"Make no mistake, we must all work together as an industry if we are to succeed in keeping racing going within Victoria."
Extra jockeys' rooms will be made available to the 25 riders. Multiple sets of scales will also be used for weighing-out and weighing-in to segregate the jockeys.
