Irish jump jockey Andrew McNamara is to retire from race riding to become a trainer.
He won the Queen Mother Champion Chase at the 2006 Cheltenham Festival on Newmill and the 2008 Irish Champion Hurdle with Sizing Europe.
The 6ft jockey said his retirement was due to being "plagued" by back trouble, not the injuries to his relatives.
McNamara, said: "Between my height and keeping my weight right, I am now moving on to what I always wanted to do - training."
His other big-race victories among 15 Grade One wins included the 2007 Irish Hennessy Gold Cup on Beef Or Salmon and the 2010 Irish Grand National aboard Bluesea Cracker.
McNamara will ride for the last time at the Tramore Festival this weekend.
