Brendan Sexton, Australia. Age at the Olympics: 27
Brendan Sexton announced himself as a podium contender for the Olympics when he finished second at the Mooloolaba World Cup last year, fourth at the Sydney leg of the World Triathlon Series and then won the Monterrey World Cup—three breakthrough performances after years of injury and a horrific bike crash in 2009. Although he faded towards the end of last year, he’s one of the few athletes on the men’s circuit with the top-end run speed needed to compete with the Brownlees and Javier Gomez. Now the issue is getting on the Australian Olympic team—so far the only man who has a guaranteed spot is Brad Kahlefeldt.
