But offering her extra hope for Monday is that her reputation as a "chronic, addictive, obsessive, over-trainer" has been tempered by no Ironman activity since late last year.
"The body is not fatigued," she said from Auckland yesterday as she prepared for the first event of the triathlon festival, the Aquathon (1km swim, 5km run), in which she later earned an age-group bronze medal.
Her unofficial coach Ken Maclaren said there was no discernible difference between Hollington's swimming and cycling now, to 20 years ago when she was an elite athlete.
"She's in great shape. She's in great form. She's got a good chance to win this and add it to the long distance [title]."
Several other Hawke's Bay athletes have podium chances with perhaps the most in-form being Bridget Lodge in the 25-29 age-group, and Naomi Fergusson in the 30-34 age-group. Both lowered the VLK Friendly Dental Long Course Duathlon record during the winter, before "The Alinator" came back from a winter in Europe to put her name in the book.
"You never quite know who's turning up," Hollington said of the World Champs.
