“We waited with bated breath for the results as we were only 20 points ahead before the relays. Our team was fantastic on the day and winning the girls aggregate and junior boys shield was fantastic. However when the winning school was announced our team was ecstatic.”

Mr Longbottom said the whole school was proud of what the students had achieved.
“We have waited five year to hold up the shield again, but it was well worth the wait,” he said.
