Wayne Osbourne knows he'll be a marked man at this week's blokarting national championships.
The 56-year-old Aucklander, who is a self-employed builder, has won pretty much every race he has entered in the past 12 months.
Osbourne won last year's New Zealand championship, the North Island, South Island and North America championships and he capped it off with a win at the world championships at Ivanpah Dry Lake in April.
"It's has been a dream run really," said Osbourne. "I have really enjoying competing and, yeah, of course it's always fun to win."
This week he is looking forward to the competition in his super-heavyweight division.
