Today Ben Gouldsbrough will be climbing walls, hurdling water, and leaping through tyres to prove his school is the toughest.
The 12-year-old will be competing against 2500 other students from 45 Hawke's Bay schools in the Mitre 10 Mega Tough Kids event.
Ben said he knew what to expect from the 26-piece obstacle course after competing last year, enjoying the hill climbs, slides, and running through water the most.
"It taught me you can't give up and you need to keep trying," Ben said.
Ben, with 89 other Hastings Intermediate students, will be competing together for their school, and against one another for spots in the school's sports academy.
