Hundreds of people will be covered in colour when they take part in a Wanganui Collegiate School World Vision fun run.
The Colour Dash will be 4km long and at various distances coloured powder will be launched at the participants.
It is all about raising money for World Vision as the 40 Hour Famine approaches, this year focusing on raising funds to fight famine in South Sudan.
Year 13 student Ethan Gillespie, 17, is a key organiser of the event.
"It's a fun run over 4km, every kilometre is an achievement so at these stages you will get colour powder thrown at you to celebrate.
