You've heard of the tough mudder challenge- now you can do the ruff mudder challenge!
There's just TWO more weeks left to get registered and get you and your dog at the outing of the year in Cairns.
The K-9 challenge will be held over two days at Cannon Park this year, and it's set to be one of the best days of your life.
If you don't want to get muddy, or just want to laugh at your friends taking part, then it's free entry for you.
Organiser Phill Reuben says he wanted to bring something different to Cairns, following the success of the Kryptonite Challenges.
"Anyone, any dog can enter, but please don't enter two dogs if you can't control them on your own."
"Teams are very welcome, and dogs can be any size, just as long as everyone's having a good time."
Don't worry, you won't head home muddy, there'll be a free wash off area you and your pooch can head over to before jumping in the car.
Saturday 30th March will see runs from 7am to 9am.
Sunday 31st March will be all day, from 8am to 3pm.
