Newtownards cyclist Martyn Irvine believes he can win a medal for Ireland in the Omnium event in London.
Irvine faced a huge task to qualify for the Olympics but achieved his goal by breaking into the top eight in the European rankings.
"I've been training with a medal in mind. It's all about putting together my best races on the day. And If I can accumulate my best six races, I'm well able to be standing on the podium in London."
