For 25 years the Julia Creek Dirt n Dust Festival has been churning out triathletes ready for Australia's toughest sprint triathlon, but none are as tough as the competitors in the Julia Creek Junior Triathlon.

Competitors as young as four years old battle it out in a race that rivals its big brother.

These mini-triathletes are gearing up to kick off the Festival this Friday afternoon.

Dirt n Dust Committee President Stephen Malone says that holding the event during the school holidays ensures the Festival remains an event for the whole family.

"The Dirt n Dust Festival really is a family affair, especially for some families, whose kids run in the Junior Tri while the parents tackle Australia's tough sprint tri in the South 32 Senior event," Mr Malone said.

"We hold the Festival during the school holidays to encourage families to head out west to experience Outback Queensland. It also gives kids a healthy activity to burn up all that school holiday energy."

This year the Dirt n Dust Festival ran workshops for schools along the Overlander's Way in preparation for the Junior Triathlon.

"We visited most of the schools between Townsville and Mount Isa," Mr Malone said.

"Running workshops with the students on team building and fitness. We had a seasoned athlete who spoke to the kids about the upcoming triathlon and taught them valuable skills around triathlon transitions, as well as tips for the different legs.

"The aim was to get them excited about exercise and the upcoming event. They can then bring those skills to the event and compete."

He said the workshops succeeded in generating renewed interest in the race, with nearly 100 juniors registered, up from last years numbers.
