Former National Hunt star Master Oats has died today at the age of 26, after suffering a heart attack in his field.
The gelding was best known for winning the Cheltenham Gold Cup in 1995, when ridden by Norman Williamson. Master Oats won a total of 10 races in his career.
After finishing fifth in the 1997 Grand National, he was retired - but continued to enjoy life as a hack and hunter.
His trainer Kim Bailey confirmed the news on Twitter today, paying tribute to his former charge: "A hero to me, his owner and a great racehorse. He had a wonderful happy retirement."
