In an unfortunate incident, Danielle Otter, a swimming teacher who broke both her ankles while competing at The Stampede, an obstacle course race in Australia. As a result of her horrific injuries, Otter, 44, is unable to walk normally.

Otter claimed she was injured when her legs became entangled in a slip and slide obstacle at a race organised in 2014. She has filed legal action against the operators of the Stampede, a 5 kilometre and 10 kilometre mud-soaked event, similar to the popular obstacle race Tough Mudder.

The Stampede featured a series of obstacles, court documents show, including a “slip n slide”, which involved competitors slithering at speed down a hill covered with water-soaked plastic sheeting before plunging into a mud pool at the bottom.

Ms Otter claims that after an attendant told her it was her turn to slide down the hill she became tangled in a hole that had developed in the sheeting.

“The plaintiff’s legs went into the hole at speed causing her to break both ankles,” the writ said.

Law firm Maurice Blackburn is acting on behalf of Ms Otter and has claimed that the operators of the Stampede were negligent in not properly securing the sheeting and alleged that there was no regular inspection of the sheeting.

According to the court documents, Ms Otter required surgery to repair her broken ankles, which has left her unable to walk normally. She has not returned to work as a swimming teacher since the injuries.
