The event was postponed last week and again on Wednesday because of wet weather and convener Mick Enright, of Alexandra, said it was the first time in at least 20 years that had happened.
The temperature reached 23degC yesterday, sending spectators and supporters to the shaded areas around Molyneux Park.
The top athletes from the day have the chance to take part in the Otago Primary School Athletics later this month.
