The Lambourn-trained racehorse Many Clouds has collapsed and died after winning a race at Cheltenham today.
Many Clouds, trained by Oliver Sherwood, has won both the Grand National and Hennessy Gold Cup.
Sherwood has described him as a "horse of a lifetime".
Just after reaching the winning post, the 10-year old collapsed and died from a suspected heart attack.
It sent the stunned crowd into silence and left the Lambourn trainer emotional: “He's been the horse of a lifetime and I always said he would die for you and he's died for me and the team today doing what he does best."
