TRIATHLON: By the size of Grace Pollock's smile, you wouldn't know the young girl had just swam 100m, rode 2km and ran 500m.

The primary school student won the first place medal in the under-9s age group at the Royal on 99's Double Tri event on the weekend, joining triathletes between 7-70 years of age.

Joined by fellow young athletes, Grace spoke to the Western Star about seizing victory in her third triathlon event.

"The swim is my favourite part,” she said.

"I had a lot of fun, and can't wait to do my next one.”

Setting themselves apart from other rural triathlons, The Royal on 99's Double Tri was a success.

On Saturday, the event kicked off with the first sprint triathlon, before competitors backed it up for the same legs on Sunday morning. Later on, the roads and pool were cleared for junior competitors to take the scene.

Maranoa Triathlon and Multisports Club president Meg Lyons said the event set Roma apart from other triathlons in Queensland.

"We wanted to see what could make us different,” Lyons said.

"So we decided if people were going to travel out for this event from Toowoomba or Brisbane, we wanted to make it worth it for them.

"They cover the same amount of distance as an Olympic distance, they just get that extra challenge of doing a leg on Saturday afternoon and one on Sunday.”

Lyons said it was encouraging to also see such keen interest from junior triathletes.

"Kids love a team event, a lot of them are from team sports, so they get their mates together and just have a go. Triathlon is individual, but you still kind of feel like a team,” she said.
