Mernda’s Rhiannon Wilson is on a mission to prove she is tough enough.

Ms Wilson has signed up to take part in next weekend’s Tough Mudder event at St Anne’s Winery in Myrniong.

It will be the first time she has tackled the course, which sees participants test their mental and physical stamina over a challenging 16-kilometre obstacle course while often deep in mud.

Ms Wilson said she signed up to challenge herself. “I recently got into fitness and wanted to do something for myself,” she said.

“It was my challenge to myself to see how far I have come.”

Tough Mudder is on October 28-29.
