Hosted by UK Running Events, the iflatable 5K course was held in north Leeds at the weekend.
It featured a total of 32 gigantic obstacles for competitors to try, along with five "pumping music zones" to motivate runners around the course.
Here are some of the best pictures captured by our photographer at Harewood House at the weekend.
