The management team at Down Royal Racecourse has announced its intention to run next Tuesday's St Patrick's Day race meeting behind closed doors.
The decision has been made in response to the announcement of nationwide measures to combat the spread of the coronavirus.
Emma Meehan, chief executive of Down Royal Racecourse, said: "We apologise for any inconvenience caused. However, the health and safety of racegoers is our priority.
"Only runners, riders and trainers will be in attendance, with turnstiles closed to racegoers.
"Ticketholders will automatically receive a full refund within 14 working days."
