SIBLING rivalry is the only thing separating the end of a brilliant summer of triathlon.

The Salamander Bay brothers finished 14th in their respective National All Schools Championship races in Redcliffe, Queensland recently - that was after both finishing sixth in their state-level qualifiers.

There's nothing separating us, it get's pretty competitive, said older brother Bryce, 16.

He and Morgan, 14, were both young for their age divisions at the nationals, which bodes well for their 2012 chances.

Bryce was the third competitor out of the 750m swim, ninth after the 20km ride and had slipped to 14th in the field of 46 by the end of five-kilometre run.

Given it was my first year at nationals I didn't really have any expectations so I was stoked with 14th.

I have one more year at school and I think I'd be looking to medal next year.

Bryce backed up his individual effort to do the swim leg in the teams event the following day, with his team taking out the national title.

The pair train twice daily, six days per week and can barely believe their own infatuation with the sport after just their second season.

You hear about guys training 26 hours a week and you don't believe it, then six months on there you are, you're right into it yourself, he said.

We would both love to make a career out of it.

That's a few years away yet and I'm not sure what that would involve, whether it means staying here or going overseas.

The pair are well and truly etching themselves a name in the sport after finishing with impressive results at the NSW Junior Series and under 23 pro tour.

Bryce finished seventh overall out of the state's best under 23 competitors and Morgan was second at the end of the 10-round junior tour, in which he could contest the same age group next season should he decide not to join the pro tour with his brother.
