"In fact, I did my first standard distance triathlon at the New Zealand champs in Auckland a few weeks ago and felt quite happy."
The standard distance at the worlds in Canada involves a 1.5km swim, a 40km cycle leg and a 10km run and Steward is comfortable about all three disciplines.
"My strengths are probably a balance between all three disciplines. They just require different training regimes than my usual endurance racing and I'm happy with where I'm at leading up to Canada. Of course, you don't get to this level without an awful lot of support."
Steward has been helped by work colleague Dan Morrissy for his swim legs, former World cycling bronze medallist Gary Anderson, Diane Arbuckle for overall training and chiropractor Greg Miles to ensure his body remains intact.
"My family have also been staunch supporters and without all that help I wouldn't have made it this far. This is not an individual effort," Steward said.
His son, Lloyd, is also an accomplished athlete and competed at last year's Coast to Coast.
"I chose not to do the Coast to Coast this year preferring to concentrate on the worlds in Canada instead. Again, there are different training regimes required."
At 56, Steward is in the middle of his age group and knows there are numerous quick athletes in this group.
New Zealand selectors have chosen four athletes in each of the age groups.
