As London 2012 approaches, RTÉ Sport and Cadbury have teamed up to offer you the chance to win one of hundreds of prizes.

To be in with a chance to win, all you have to do is select your favourite Irish Olympic moment from a shortlist of four: Ronnie Delany’s 1500m gold in 1956; John Treacy’s marathon silver in 1984; Michael Carruth’s welterweight gold in 1992; and Sonia O’Sullivan’s 5000m silver in 2000.
