The race club's 'Tradie's Race Day' was set to take place from 12pm on Friday at Skellatar Park, however the club said the event would be rescheduled in consultation with NSW Racing.

"Please note that due to over 38 mm of rain falling last night, the Muswellbrook Tradies Race day scheduled for today, Friday November 26, will be postponed," Muswellbrook Race Club said.

"We will notify race stakeholders once NSW Racing comes back to us with a formal date or decision."
