John Dunlop calls time on training career after 46 years Twice winner of the Epsom Derby with Shirley Heights (1978) and Erhaab (1994), Dunlop, 73, also saddled three St Leger winners in Moon Madness (1986), Silver Patriarch (1997) and Millenary (2000). Snow Fairy most recently won the seventh Group One of her incredible career when landing the Irish Champion Stakes at Leopardstown in the hands of Frankie Dettori. Dunlop said: "I can confirm that I'll be retiring at the end of the current Flat turf season. There are several reasons behind the decision. I now have much reduced stable numbers and it is now less viable than it once was. My wife has also been ill for quite a while as well, so that has been a factor and I can also now live in the shadow of my very successful sons. I don't want to get involved at the moment (in talking about his career), it is a little bit too fresh. I talked to the staff this morning and my owners yesterday and today. It's very much fresh off the printing machine. His son Ed added: "It's difficult to know where to begin, he's been at the top of the tree for so long. He's trained two Derby winners, numerous Classic winners and has been champion trainer. He's been a great inspiration to me and my brother and we obviously wish him a long and happy retirement. It's going to be a sad day for not only the whole Dunlop family when his career does come to an end at the end of the season, but I'm sure all his staff and his owners.
