A year after setting the bike course record in Kona, Australian Cameron Wurf is confident he can be a factor on the run as well.
Everyone knows Cameron Wurf can out-ride the best - now he's out to prove he can run with them as well.
The Australian will be an intriguing factor in Sunday's (AEDT) Hawaiian Ironman triathlon world championships.
A year ago, in his first attempt at the race as a professional, the former professional cyclist blitzed the 180km bike leg in a course-record time of 4hr 18min 54secs.
That gave him the race lead for the start of the marathon run.
But given the former Olympic rower had only seriously targetted Kona for a few months, it was no surprise that he faded to 17th.
Wurf had ramped up his preparations this year, competing in six Ironman-distance triathlons.
Most top professionals will only do one or two before Hawaii.
But there is method to this madness, with Wurf teaching his body how to run on tired legs.
After only managing a 3:19 at Kona last year, Wurf has run a couple of sub-three hour marathons in Ironman events.
If he can marry that running improvement with his scorching bike talent - and limit his losses in the opening 3.8km swim leg - Wurf could become a contender.
"It's been a 12-month focus for this and everything has gone to plan, so I'm ready to go," Wurf said.
"The fact I wasn't running well wasn't because I was doing anything else wrong, it was just I wasn't conditioned.
"I wasn't a good enough runner off the bike.
"We backed ourselves that it would come together after a block of work like that ... we're on the right rack."
Wurf's sporting career was going nowhere in January last year - he no longer had a pro cycling contract and was looking at doing something with his economics degree.
But a 10pm phone call turned his life on its head.
It was Australian coach Tim Kerrison, who works for the Sky cycling team, asking him to come to the Gold Coast and train with Tour de France champion Chris Froome.
By the next afternoon, Wurf had flown from his Tasmanian home and after talking with Kerrison, quickly reignited his sporting passion.
He decided to aim again for the Hawaiian Ironman, having finished it once before as an age grouper, despite a foot fracture.
"Last year was sort of the first year for me back after two years in the wilderness, not really knowing what i wanted to do," he said.
"It just took a very unexpected turn, to where we are now."
