Ninety students from 15 Wanganui district schools competed in the Toughen Up challenge at Mitre 10 MEGA on Saturday, September 13.
The challenge was a warm-up for the Mitre 10 Mega Tough Kid event to be held at Cooks Gardens on October 31.
Event manager Rachel O'Connor said the school teams competed in wheelbarrow races, apple bobbing, nail banging and target throwing races.
"Each team had an adult parent or teacher who had to sit in an ice bath until all team members had completed the challenges.
"They were there for five to 10 minutes depending on how fast the team was.
