On the same card, Royal Pagaille enhanced his growing reputation with a superb 16-length victory in the Peter Marsh Handicap Chase, though trainer Venetia Williams would not be drawn on whether he may now line-up in the Cheltenham Gold Cup come March.
Dan Skelton’s Roksana was another to confirm her Festival credentials with a classy success in the Matchbook Betting Podcast Mares’ Hurdle at Ascot, beating 2019 Grand National runner-up Magic Of Light by eight lengths.
