Greg Bennett (born 2 January 1972, in Sydney, New South Wales) is a motivational speaker, corporate trainer, and entrepreneur.

Bennett started eighty-two ITU World Cups, won six, and was on the podium twenty-three times.

Bennett represented Australia at thirteen World Championship Triathlons, three World Duathlon Championships with a silver medal in 2002, two Goodwill games, and qualified for two Australian Olympic teams.

Bennett won the Life Time Series for three consecutive years: 2006, 2007, and 2008.

Bennett placed second in the 2009 Life Time Fitness series even after being hit by a motorist in August 2009 after a training ride in his hometown of Boulder, CO.[4] Bennett won the 2011 World Championship (no drafting) in Des Moines, Iowa, just shy of his 40th Birthday.

[5] Often heralded throughout their careers as the ‘world fittest couple,’ there’s little debate that the Bennetts were worthy contenders of that title during their 16 years as Married Professional Triathletes.
