Afterwards, the children will be presented with medals back at their school assemblies, while each entry received goes into the draw for that pupil's school to win a $400 voucher for sports equipment.
The other prize givings will be held following the race at Moutoa Gardens, with the prospect of a free sausage sizzle.
There is no "walk up" for entries, which can still be made right up until the evening of December 8, with the marathon walkers being first away at 6am, followed by the runners an hour later and the other categories roughly 30 minutes apart, with the Kids run setting off at 12.30pm.
Conder said there would also be new race packs this year, while all events will be professionally timed by the 'The Timing Team'.
"All we're trying to do is make the race bigger and better," he said.
