Kids had some fun taking on the water slide at the seventh annual Portobello Paddock Pursuit.
Organiser Lyn Pope said about 590 competitors, the most so far, braved showers to attend.
Entrants had a bath in a slime pit of water and soap flakes, followed by a water slide run by the Portobello Volunteer Fire Brigade after a muddy obstacle course.
Mrs Pope said she understood more than $3000 had been raised for Portobello Community Inc.
The money goes to community groups on Otago Peninsula.
