Gr.1 Melbourne Cup (3200m) winner Dunaden has died after a paddock accident at Overbury Stud in England aged 13.
Owned by Qatar Racing, Dunaden won the 2011 Melbourne Cup for Sheikh Fahad Al Thani and returned to Australia the next year to claim the Gr.1 Caulfield Cup (2400m).
He was trained in France by Mikel Delzangles and was ridden to his Melbourne Cup win by Christophe Lemaire who was a late replacement for suspended Australian Craig Williams who rode him the following year to his Caulfield Cup victory.
"It is with great sadness that we announce triple Group One winner, Dunaden, winner of the 2011 Melbourne Cup, sadly died at Overbury Stud yesterday due to complications following a paddock accident" Qatar Racing said on Twitter.
At his next start following his Melbourne Cup success, Dunaden won the 2011 Gr.1 Hong Kong Vase (2400m) with Williams aboard.
