Thousands of people are expected to attend Racing Rotorua's flagship race day - the Campbell Infrastructure Rotorua Cup.
To be held at Arawa Park tomorrow, the $75,000 cup event will be entering its 70th year.
While the horses will be the main attraction, TRAC marketing sponsorship and events manager Don Paterson said there would also be plenty of entertainment for the crowd, including children.
"There's a good selection of different rides, bouncy castle and a magic show as well as live music in between the races with a couple of local musicians including Diane Tibble," Mr Paterson said. "It's mainly about the horses. Rotorua only gets one cup day a year."
Also on offer will be a $250 bet competition. Participants need to take a selfie photo in front of the winning post for race four to be in the draw. Further details are on the TRAC Facebook page.
