Bevan Docherty, New Zealand. Age at the Olympics: 35
Like his good friend Simon Whitfield, Bevan Docherty has two Olympic medals: bronze from Beijing in 2008 and silver from Athens in 2004. But unlike Whitfield, he lacks gold, and he’s been vocal about his intentions to earn it this Olympic cycle. Although his performance on the World Triathlon Series has been spotty of late, he did win the Edmonton World Cup last year, placed second at the brutal Auckland World Cup, and he won the Sydney leg of the World Triathlon Series in 2010 before abandoning the rest of the season due to overtraining. And like Whitfield, Docherty knows how to race and show up big on the big stage. Don’t count him out.
