Ben's father Paul was full of praise for what the Tough Kids event was teaching his son and other students.
"It gets kids to have a go essentiality at something fun and they'll probably surprise themselves sometimes at what they are able to do," he said. "It will spur them on, so they think 'I can do more than I thought I could'."
Organiser Kerry Meehan said this year was the biggest in the three years the event had been running with organisers agreeing to take an extra 500 entries.
Organisers were hoping to raise between $6000 to $8000 for Breath HB from entry fees, and food purchases at the event.
"We found asthma is quite an issue with some of the kids who come along," Ms Meehan said, "One of our main concerns was a lot of kids were finishing the race, and needed an inhaler but either didn't have it there or didn't have one at all."
Ms Meehan said 100 per cent of the money spent on food at the event would also be going to Breath HB thanks to Rapid Release, who were supplying food free of charge.
About a third of the schools would be competing for the first time this year, like the 99 from Taradale Intermediate school. It would also be the first year for up to 100 students from Mahora School.
A school representative said: "It's a different opportunity for the kids. It's another experience outside the classroom where they can challenge themselves."
Others, like Hastings Intermediate School have been competing every year since the event began, said deputy principal Shane Foster. "The variety of challenges it provides, it's fun but it's still good competition. It's always good to offer something different for the kids."
