George Boughey has further reflected on the life-changing experiences provided by Bow Echo (Night Of Thunder) following the retirement of the unbeaten colt on Tuesday due to an injury to his left fore fetlock. I didn't think a horse like Bow Echo would come along quite so soon. Boughey added of the injury which brought the curtain down on Bow Echo's career, “It was obviously upsetting news yesterday for a lot of people – he's captured the imagination. “I do everything in the best interests of the horse to stop an injury that could be catastrophic happening. Bow Echo retires unbeaten in six career starts and having registered a hat-trick of Group 1 victories this season, becoming the first horse since Frankel in 2011 to win the 2,000 Guineas, St James's Palace Stakes and Sussex Stakes.
