Bowden, in defending her 2000 title, also broke her own run course record, clocking a 3:01 marathon to best last year's 3:06. Her 9:00:18 put her more than a half-hour ahead of her closest competitor, Australia's Belinda Granger, who came home in 9:32.
Granger's finish moved her up two spots on the podium over last year's fourth-place finish. Behind her was Australia's Yoko Okuda in 9:34, a student and first-year pro who notched a great improvement on her 30th place finish here last year.
Aussie Joanne King, one of the pre-race favorites, finished in fourth in 9:37 with fellow Aussie Susan Peter, a 38-year-old pro who works as a teacher, came fifth in 9:40. Ironman vet Jan Wanklyn of Australia was eighth in 9:48.
Stadler biked away from the field with a 4:42 bike split, then ran 2:58:15 to seal the win in 8:30. Behind him was Ironman veteran Jason Shortis of Australia, who finished in 8:41 to take second place. Shortis has finished fourth, sixth, and third in the race and now achieves his highest spot on the podium. He was also the only man besides Stadler to post a sub-3:00 marathon, going 2:58:22.
In third was Canadian Garrett MacFadyen, now training in Australia, in 8:45. MacFadyen was eighth in Australia last year, and fourth at Ironman Malaysia in January. Rounding out the top five were Belgian Marc Herremans in 8:47 and David Meade of Australia, winner of the Sri Chimnoy Peace Triathlon in February, in 8:49.
American Tim DeBoom made an early exit from the race after reportedly overheating in his wetsuit.
