Loder To Quit Training David Loder has announced he will retire from the training ranks at the end of the season.The Newmarket handler has cited health problems as the main reason behind his decision to call time on a 13-year career.Loder initially intended to bow out of training in 2003 after a lean spell but improved results encouraged him to prolong his career.However, the 41-year-old has underlined that this time his decision is final.He told the Racing Post: 'I´ve had one or two problems with my health and have found it difficult to do the job as well as I´d like.'I was hospitalised in by a virus in France and I´ve never completely got rid of it. Training is stressful and triggers it off and it will be better for me to take a step back.'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.'Retirement has been in my mind for a while - this isn´t an overnight decision.'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.'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 added: '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.' ?
