Contestants from Sport Otago prepare for the Night ‘n Day Rainbow Run in Alexandra. The run on Sunday is based on the colourful celebration of the Indian Holi Festival. Participants run and walk a 5km course around Molyneux Park, being brightly decorated as they go. The colour is provided by a nontoxic powder which washes away easily. Children 12 and under must be accompanied by an adult. Ticket details from sportotago.co.nz.
