The winner of the competition was Tamilore Awonusi from Kilkenny College. He completed the slogan "Ian and the C4 Cactus are such a great match because..." with "both are one of a kind". It was chosen as Madigan's overall favourite from the many entries received.
Tamilore and nine of his friends attended a training session with Madigan at Blackrock College recently where they had the opportunity to train one-on-one with the rugby star.
The group also enjoyed a Q&A session with the player at the event, where they picked up some handy hints and tips for improving their own game as members of the Kilkenny College rugby team.
