This was part of the whole festive fun feel to the event, he said.
"Some people will still be racing, but it's trying to foster that whole social wellbeing and environment, to get out when it's normally quite miserable in winter."
Farmer said the race had sold out within four weeks of opening. The event's second release of entries had also sold out, and it was anticipated there would be 1200 participants.
He encouraged people to come along to support the runners and check out the live DJs.
He said there was plenty to see and do, such as the Treewalk at the Redwoods.
