Australian sprinter Anna Meares says she will draw on the enthusiasm of a young team in her attempt to beat GB rival Victoria Pendleton in London.
Meares, 28, one of only two Olympians in Australia's track squad, is trying to win a medal at a third Olympics.
"I'm not saying anything personal against Vicky," Meares said. "We're both competing for that gold medal and unfortunately only one of us gets it."
She will compete in the individual sprint, team sprint and keirin events.
"This is a young team," said Meares. "With youth comes enthusiasm, motivation, desire - and that is contagious for me."
