For much of the year they travel the world, following the triathlon circuit. In the last year alone they have competed in Japan, Australia, France, Hawaii, the Virgin Islands, Bermuda and throughout the U.S. and Canada. They won't say how much money they earn, but it's substantial enough that they can afford a business manager.

"It's a great lifestyle," says Sylviane. "But it's not very safe. If you get injured, you can be out (of action) for months and make no money at all. I know this can't go on forever. You have to take care of your money for the future."

Not to mention make money. Toward that end, the twins, who are part of a talented Pioneer Electronics team, will chase the $7,000 first-place prize in Monday's first Heritage International Triathlon, which will begin at 7 a.m. at the Utah Lake State Park and finish at the BYU track and field stadium.

Some are calling the field for Monday's race the best of this year's triathlon season so far. The field will include Scott Tinley, Scott Molina, Mike Pigg, Richard Wells, Andrew McNaughton, Hanssen, Baker and Cannon, among many others. And of course there will be the Puntous twins, who, even if no one else shows up, always have each other to push them to the finish.
