This year's annual 5km Colour Run, dubbed 'the happiest 5km on the planet', brings the magic and mayhem of a Rio carnival to Joburg's streets complete with stilt walkers and balloon shapers. Participating in this un-timed fun run along with thousands of other people is an opportunity to raise money, and express your individuality for a good cause. Each 'Color Runner' receives a race pack which includes a T-Shirt, headband, a bag of coloured powder to throw over yourself, friends or even complete strangers, temporary tattoos and your race number.
