The increasingly popular event attracted its biggest crowd so far to Logan Park, as runners were pelted with colourful dye while completing the 5km fun run or walk.
Runners’ mostly white T-shirts turned red, blue, purple and green, as did their faces, hair, arms and legs.
The run attracted about 2200 people, a figure Sport Otago business development and events manager Michael Smith said had risen from 1500 last year.
The event was growing naturally, and had been well marketed, he said.
The weather forecast for the day — MetService was predicting temperatures over 20degC — also helped.
The event was a fundraiser for Sporting Chance, a Sport Otago initiative that provided basic sports equipment and financial assistance for children affected by financial hardship.
Mr Smith said the need to hold the event within Logan Park without closing or crossing roads — which would have required traffic management and cut into funds — meant there were "bottlenecks" early on.
The large numbers exacerbated that situation.
The run will be held in Alexandra and Oamaru next month, and in Balclutha in November.
