Joseph O’Brien quits riding after ruling Aspen Colorado out of Cheltenham

The move had been widely expected as the record-breaking jockey had been turning his attentions more to the training side and is in the process of taking out a full licence.
O’Brien, 22, has been playing a key role in helping his father, trainer Aidan O’Brien, with a large string of horses recently, including JCB Triumph Hurdle favourite Ivanovich Gorbatov, from a base at Piltown, County Kilkenny, where the great Istabraq’s triumphs were originally masterminded.
