Sceaux stands out in Arkle list Hot favourite Un De Sceaux heads a list of 19 horses to stand their ground in the Racing Post Arkle Challenge Trophy at the Cheltenham Festival next Tuesday. Willie Mullins' charge is a general 4-7 chance ahead of the race but he has not scared off many rivals, with the likes of Paul Nicholls' Vibrato Valtat, the Nicky Henderson-trained Josses Hill and Gordon Elliott's Clarcam still in the mix. Mullins has extra strings to his bow in Vautour and Adriana Des Mottes, while Mick Channon's Sgt Reckless is another of the leading home hopes. Melodic Rendezvous finished seventh in the Champion Hurdle last year but may try his Festival luck over fences. God's Own was a Grade One winner at Punchestown last May and may bid to add a Festival win to his CV. Chris Pea Green, Cold March, Court Minstrel, Dunraven Storm, Sail By The Sea, Smashing, Ted Veale, Three Kingdoms, Top Gamble and Turn Over Sivola are also still in the mix.
