Horsham's Holy Trinity Lutheran School and Ss Michael and John's Primary School, Warracknabeal Secondary College, Warracknabeal's St Mary's Catholic Primary School, Stawell West Primary School, Donald High School and St Arnaud Secondary College will all compete in the event in November.

Holy Trinity team co-ordinator Chris Surridge said the students were training three times a week for the event.

"The primary school students will race in the human powered vehicle for 14 hours and do a presentation to judges," he said.

"Also this year we have the EEV, energy efficient vehicle, which our year seven team is racing for 24 hours.

"The students are excited and nervous at the same time."

Mr Surridge said 45 students from years five to seven were involved.

"Students are doing physical training during the week, plus lunch-time meetings to prepare for the presentation," he said.

"They will present to the judges about what they have been doing and all the educational stuff that goes with it.

"It's not just about the race there is a focus on sustainability and technology."

Mr Surridge said the school had participated in the event for the past six years.

"We started the first time with 14 students and a ute now we have trucks, buses and 45 students and we have entered primary and secondary teams," he said.

"It gives the students a challenge. It is about building self-esteem, confidence and team work.

"I like seeing the personal growth in the students and, to be honest, it is something that gets in your blood a bit."

Mr Surridge said the community had also got behind the team.

"We get a lot of support from businesses that help with donations and sponsorship, which is fantastic," he said.

The challenge will be at Maryborough from November 20 to 23.
