Apolon De Charnie shocked the Cheltenham crowd with a 50-1 victory in the JCB Triumph Hurdle.
Trained by Willie Mullins and ridden by his son Patrick, the four-year-old was aiming to keep the trophy in the Closutton stable after Poniros struck at 100-1 on what was his hurdling debut 12 months ago.
Though not quite as overlooked in the betting, the Edward Ware-owned gelding was still a surprise first head across the line, with 5-1 chance Maestro Conti behind him and Minella Study (7-1) in third.
