Jan Frodeno, Germany. Age at the Olympics: 30
We haven’t heard much from Frodeno since he won gold in Beijing in 2008. But Frodeno proved four years ago that his résumé going into the Olympics means nothing, as he came out of nowhere to outsprint Canada’s Simon Whitfield, New Zealand’s Bevan Docherty and Spain’s Javier Gomez for gold. He placed 10th at the Olympic test event in 2007 in Beijing, one year before the 2008 Beijing Olympics. His place at the London Olympic test event last year? 11th. Perhaps that’s a sign of things to come. That he’s also a great sprinter bodes well for him, as ITU triathlon has a tendency to come down to the final meters, especially on flat courses like London.
