More than 50 students and staff at Hallam Senior College hit the treadmill as part of a 24-hour walkathon fundraiser.
The personal development class raised $350 for Heavy Metal, which runs mens behaviour change and anger management groups.
Over the day-and-night event, the team ran 134 kilometres.
Seventeen of the students stayed up during what was described as a long, hard night.
The college is also screening the powerful family-violence documentary Call Me Dad.
The film delves into a local Heavy Metal mens behaviour change group, and how men are challenged to change their violent ways.
It screens at Hallam Senior College on 1 November, 7pm, followed by a Q&A with counsellors David and Jacqui.
