However, one still escapes his grasp and it's arguably the most important to him.

That race is the ultimate Huskisson Triathlon, which returns to Jervis Bay for the 16th year this weekend.

"The preparation for this year's race has been great," Lewis said.

"I have ticked off every session the best I can and will have no doubts come Sunday that I have done everything I could do."

The St Johns alumnus has competed at the annual Husky event every year since 2011 - with this year marking his sixth long course race.

"My plan for Sunday is to do everything I can in the swim to make it out with a solid pack of athletes," the 28-year-old said.

"I have worked extremely hard on my swim and really want that hard work to show on Sunday.

"If I can make that happen, then I believe I can be in the mix for my best result."

If the Jervis Bay Triathlon Club professional triathlete is to do so, he will have to overcome the strongest field Huskisson has seen in years.

That field includes professionals Leigh Anderson, Scott Bayvel, Sam Betten, Jarrod Harvey, Simon Hearn, Lachlan Kerin, Caleb Noble, Kieran Storch, Edward Vining (all Queensland), David Mainwaring, Tim Reed, Tim Van Berkel, Joel Woolbridge, Josh Woolbridge (all NSW), Levi Hauwert, Levi Maxwell, Fraser Walsh (all Victoria), Blake Kappler (Western Australia), Steven McKenna (South Australia), Adam Rudgley (ACT) and Trent Thorpe (New Zealand).

"This is by far the strongest Husky field I have competed and seen in my lifetime," he said.

"It's great to have all of Australia's best on the start line for the national championship."

If Lewis was able to cross the line of the 1.9km swim, 90km bike and 21.1km run course in first, he admits he would be over the moon.

"It would mean the world to me to win this race," he said.

"It's honesty my number one goal to achieve as a professional athlete above anything else.

"However, I have to be realistic and say I think my time will still be two to three years away.

"I'm really looking to having a strong performance and to keep building my career race by race."

The 13 professional women who will be lining up on Sunday include NSW's Amelia Watkinson, Courtney Gilfillan, Helena Hayes, Renee Killey, Moya Johansson and Penny Slater, Queensland's Ellie Salthouse, Kirra Seidel, Kylie Simpson and Shannon Sutton, Victoria's Laura Armstrong and Grace Thek and South Australia's Chloe Lane.
