Some may bear a grudge, but not Kane Radford. He's put his non-selection for the Beijing Olympics well behind him and is even more determined to prove he should feature in the London Olympic swim squad.
Radford, 20, flies out to Shanghai tonight as a member of the State AquaBlacks competing in the Fina World Swimming Championships this month.
The championships begin with the open water events from July 19 to 22 with the pool events from July 24 to 30.
Radford contests the 5km open water event on July 22.
"Reaching the London Olympics is the main goal," Radford said.
"Beijing I've put behind me. It happened and I'm now looking forward to the now."
The 5km open water swim is Radford's speciality. He took second at this year's New Zealand championships and knows what he has to do to get first.
"I've no particular tactics at this stage,' he said.
"I know I have to swim the right way. I want to set the pace, save as much energy as possible until I really need it. It's a touch mat to finish in the water so you have to time [your strokes] just right or you can miss on on places."
That was his downfall at the nationals in Taupo this year. With 500m to go it looked as if the title was in the bag, but the last 200m turned into a washing machine and it was Bryn Murphy who hit the mat first.
Radford, who is swimming between 70km and 80km a week, has no expectations of where he will place.
He's yet to experience the heat and humidity Shanghai will offer the swimmers.
He knows the field will contain the usual opposition - he raced the Australian open water championships earlier this year and has also raced overseas in the past.
"I've raced most of the guys before ... I see it as a stepping stone to keep moving upwards. It can only be a good thing."
After the world championships he will turn his attention to the New Zealand Open Water Championships and London selection.
Radford flies out at 11 tonight.
