"Suddenly, after announcing this, we've got more than 30 students who are committed to doing as many laps as they can, up to the golden 100, and hoping that individuals, businesses, organisations and the like will get in behind them," he added.
People were jumping on board with the best pledge as of last week $1 for every lap up to 100 laps.
"We also have some sponsors saying they will join the kids on the walk."
It will all be happening tomorrow afternoon, starting at 12.30pm. Pledges and donations will be welcomed at the school office (phone (09) 408-2671) and there's more on the school's Facebook page.
