If crawling through mud, running just under 5km and jumping over fire is your idea of a good time, you're part of an elite group of people called 'Warriors'.
Some of these warriors live and work in the Clarence Valley, and can be seen running long distances, carrying tyres and pushing utes in their spare time.
It's all in preparation for the Warrior Dash, which will bring thousands of fitness freaks from across Australia to converge on Kilcoy, Queensland, this Saturday.
Personal trainer and head warrior Craig Nipperess said his legion was ready for the challenge.
"We've been preparing for a few weeks now," Nipperess said.
"In addition to our regular workouts we've been doing extra work by pushing vehicles and interval running."
The force of 17 warriors will take on the challenge, which will involve a long-distance run with 11 obstacles.
Nipperess said they incorporated the terrain around Grafton into their training regime.
"We travelled around the area to replicate the challenges we're going to face at the Warrior Dash," Nipperess said.
"We trained by using the lie of the land and used a few obstacles along the way."
Incorporating the old adage of "never leaving anyone behind", the warriors plan on getting through the course as one.
"Our aim is to make sure everyone gets through the course in one piece," Nipperess said.
"We're estimating for it to take an hour, but it all depends on what happens on the day."
If you thought the training and the threat of jumping over fire had turned them off - well you can guess again.
Nipperess and his crew of warriors are already looking for another challenge to conquer.
"We're already looking into next year," Nipperess said.
"Preferably around the east coast, but it depends what's on and when."
