HERVEY Bay Pony Club member Deziree Roos has left no stone unturned in the limited time she has had to prepare for the Pony Club Australia National Championships.
The Beaudesert rider has endured long, 18-hour working days, a self-imposed six month alcohol ban and three-hour round trips to the pool in an effort to make sure she's ready for next week's Toowoomba comp.
Roos will compete in the tetrathlon and as part of the quiz team.
"I definitely won't go bad but I don't expect a gold," the 22-year-old said.
"It has been tough. I've been trying to swim twice a week and I've doing boot camp and riding. Hopefully that's keeping me fit."
The tetrathlon will include running, swimming, shooting and showjumping, and will run from Monday until Thursday.
Roos said her weakest leg would be the run, while her beloved Thomas would help power her through the riding phase.
It is on Thomas she won gold at the Pony Club of Queensland Equitation and Showjumping State Championships in Maryborough in April. She will be joined in the team by fellow Hervey Bay rider Madison Hose, who will compete on APH Swashbuckler in eventing.
