Young Vinnies invited teachers, parents and fellow students to join the 24-hour walk and runathon, Mrs Hills said, with students working together to make the most of the event.
She said "rugby boys were the master chefs" running the barbecue, making hamburgers and selling cakes, muffins, sweets and drinks to feed the walkers and the runners and there were spot prizes, music and a competition "to see how many laps people could run or walk".
"Students were invited to dress up for the occasion - and they did. We had frogs, giraffes, tigers, strange green creatures and an assortment of beautiful fairies," she said.
"Age was no barrier. The youngest walker was 13-month-old Mercedes, who was happy to hold the hands of her older Chanel friends as she toddled round the track. Her proud mother was present when she was given a spot prize for her efforts."
Mrs Hills said tents were used for participants needing rest and students had kept walking all through Saturday night until 1pm on Sunday. "I wouldn't be surprised if they slept for the rest of the day."
Chanel College principal Grant Miles said two students had completed 170 laps, and he was proud of their commitment and the charitable efforts of every participant in the charity event.
