Run a Muck Perth, formerly known as Stampede in the Valley, is a 5km obstacle course race, held at the picturesque Belvoir Estate in the Swan Valley in Western Australia.
This event has been replaced with the Swan Valley MUDFEST.
Competitors will be "at one with nature" while tackling muddy, dirty obstacles. There are twenty obstacles in total, with a distance of 5km across the whole course. There is no time limit on the course, enabling people of all ages and abilities to complete it at their own pace. This race is about enjoyment and having fun rather than breaking any land speed records.
The kids event is open for children aged 6 to 10 years. They can stay on course for 45 minutes so can do as many laps as they like. One parent is allowed to accompany a child at no cost on the course.
