Leading Flat racing trainer David Loder has announced he will retire at the end of the season.
Loder earmarked Dubai Millennium as a potential star
The Newmarket trainer cited health problems as the main reason behind his decision to call time on a distinguished 13-year career.
Loder, 41, initially intended to bow out of training in 2003 after a lean spell but improved results encouraged him to prolong his career.
He said:"I have found it difficult to do the job as well as I'd like."
Desert Prince, winner of the Irish 2000 Guineas, Prix du Moulin and Queen Elizabeth II Stakes in 1998, was among the best horses Loder trained but he enjoyed huge success with his juvenile runners.
Loder also handled Dubai Millennium as a two-year-old when he was named Yaazer and it was the trainer who picked him out as a future star.
He told the Racing Post: "From 60 yearlings in the yard, my pin landed on the right one.
"I suggested him as the colt who should be named Dubai Millennium."
Loder said he had suffered health problems since being hospitalised by a virus in France.
"Training is stressful and triggers it off and it will be better for me to take a step back," he said,
"My doctor advised me to cut down on stressful things in life and training is full-on. You either do it properly or not at all.
"Looking back, I should have stuck to my guns two years ago when I said I'd retire. But my ego got the better of me. There will be no going back this time."
