UN De Sceaux is clear favourite in the ante-post market for the two-mile £150,000 Racing Post Arkle Challenge Trophy Chase at Cheltenham, for which there are 45 entries.

The seven-year-old was unbeaten over hurdles but fell on his chasing debut at Thurles in November when looking the certain winner. He made no mistake next time out at Fairyhouse on December 12th, when successful by 12 lengths. He runs on Sunday in the Grade 1 Frank Ward Solicitors Arkle Novice Chase at Leopardstown against fellow Cheltenham entries Clarcam and Gilgamboa.
