Under the bright lights of Las Vegas Elite men and women battled for a $30,000 purse in the Aussie inspired Super Sprint Tri Grand Prix.

American Olympian Gwen Jorgensen grabbed the women's title and with it the US National title. Aussie Peter Kerr took the men's race and Eric Lagerstrom earned the US National title in an exciting sprint for the second place.
